Dedicated Hot Spare vs Global Hot Spare

Hi,
Is there an order of preference in which a spare is "put into service" (a drive fails)? Here's my TS430 w/ RAID 500 card:
Two arrays:
SATA RAID 1 with dedicated hotspare for OS/boot
SAS RAID 10 with global hotspare for SQL 2008
I was unaware that one could not assign a single dedicated hotspare to a RAID 10 array. It appears that RAID 10 dedicated spares can only be assigned to each Span of the RAID 1 - this makes a total of 6 drives.
Since there isn't room in the hotswap bay for 9 drives, I have made the spare SAS drive as a global spare.
Can I assume if one of the SATA RAID drives fail, it looks at the dedicated hotspare assigned to the array 1st or solely? I know that I can not mix the SATA and SAS drives across an array, but I suspect that the SATA RAID will look at the dedicated hotspare only.
Thanks!

> Should I leave a drive out of the raid setup to create a Hot Spare?
Should you? That's up to you to decide based on a number of factors including how long you're prepared to run with a failed drive in thebox, how much storage you need (if you can afford to lose one (or two) disks' worth of storage).
> Hot Spare?are automatically added if a drive goes down right?
Correct. If a drive fails and you have a hot spare then the RAID automatically initiates a rebuid on the spare. This can take some time, especially for large arrays, during which time you risk losing your data should another drive fail.
If you don't have a hot spare then you need to manually replace the drive. This adds an extra amount of time to the window where you risk losing data, ranging from minutes (you notice straight away and have a spare disk sitting on a shelf) to days (you're away on vacation and don't notice).
FWIW, in all the XServe RAIDs I've run for years I've had one single disk failure.

Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array. The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use. I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets. I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets. I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet.
To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
Anyone care to share thoughts/perspectives? Thanks
Bill

Thanks for the speedy feedback Harm - I appreciate it.
I was thinking RAID level 3 as well.
Of course, it's always something! I purchased the Caviar Blacks by mistake - which are non-TLER. I will work with EggHead to return the ones I purchased and replace them with RE4 versions as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives - I suspect WD is way beyond that now anyway with current builds.
I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller. When I benchmark them I'll post the results in case others are curious.
Thanks again....off to EggHead!

C210 M1/M2 LSI 1064E only seeing 4 of 5 drives

I have several UCS C210 M1 and M2s, each has 5 x drives installed (72 gb). I interrupt the boot process via cntrl-c to configure the LSI 1064E RAID controller but it's only showing 4 of the 5 installed drives. I can see all 5 drives via the CIMC inventory option.
Why am I not able to see all 5 drives?
Also have one other question on IM RAID option. I am setting up two RAID arrays each with 2 drives and want a hot spare for them as well. Does each of them need it's own dedicated hot spare? or can 1 hot spare drive be available for both arrays?
Thanks,
Todd

You will want to review whether your C210 has a SAS Expander or SAS Extender. These are daughter cards plugged in the back of the drive bay and receive the connection from the array controller. By default, a C210 will have a SAS Extender. The SAS Expander is an upgrade available at the time the C210 is ordered, it is not available as a field upgrade.
The SAS Extender can provide connectivity to 4 drives per SAS cable connected to it. The 1064 only has support for one cable and is limited to 4 drives when used with the SAS Extender. The 9261 has support for two cables and is limited to 8 drives.
The SAS Expander and support up to 16 drives with a single SAS connection.

Living in Spain

Hi Guys. Am spending some months in Spain and will be taking a Macbook Air. The house where i'm stying does not have a phoneline (!). What is the best way to go online? Does a dongle work? Should it be bought in the UK or in Spain? How do the relative costs work out?
Thanks all
Scobie

The iPhone supports tethering a Mac as do multiple Adroid devices and dedicated hot-spot servers. To use your cellphone in Spain it will need to be internationally GSM compatible and most likely unlocked and then you can subscribe to one of the Spanish cellular companies to get a compatible SIM. Check with your cellphone vendor to see if you current cellphone is internationally GSM compatible and if it supports LTE and if you need to unlock it for international compatibility.
If you have had your cellphone for the requisite amount of time (40 days with T-Mobile, the end of your contract for other carriers) and you have a current contract with your USA cellular company, they will unlock your phone with no hassle. Some carriers will make exceptions to unlock your phone before the requisite time if you say you will be traveling internationally.
3G is somewhat OK for tethering but 4G-LTE is much better. If you do not have 4G-LTE compatible cellphone or hot-spot device I recommend you get one for your prolonged stay in Spain. This may be a great opportunity to upgrade to an iPhone 5/5c/5s. I am upgrading from my AT&T unlocked iPhone 4 to a 5s for this reason. The iPhone 4s is GSM internationally travel compatible but I don't think it supports LTE.
According to http://www.apple.com/iphone/LTE/ Spanish companies that support LTE are

Black bar along the right side and the bottom of the screen- DV5-1007ca

I have DV5 1007ca running Vista Home Premium 32-bit.My computer seems to suddenly think my monitor is a different size. I have a 3-inch black bar down the right side of the screen and about a 1/4 inch black bar along the bottom. My windows are still fully functional and completely fill the portion of the screen that is active. There is no loss of image, it's just framed by the black bars. If I do a Print screen and paste it into a document, the black bars are not there. It's as if the computer thinks the screen is a different physical size. This situation is present all the time, even when starting up. This is what I have done so far: -adjusted screen resolution settings = no change-rolled back my display drivers = no change-re-updated my display drivers = no change-rolled back my BIOS = no change-re-updated my BIOS = no change-System recovery = no change I searched posts here and elsewhere but the results were inconclusive. A couple of posters reported a virtually identical problem and were told they needed to replace either their screens or their graphics cards. Unfortunately, none of those posters ever reported back so it was unclear whether or not the issue was resolved. I doubt it is the screen since screen problem symptoms usually involve bits of screen not working and parts of the display being lost. My screen seems to be working fine, it just thinks it's smaller than it is. The graphics card is highly suspect. What's funny is that a little while ago, I started up my computer without changing anything and all was well for about a week and then it went back to the same old issue. Any helpful advice would be appreciated. This issue is driving me nuts!

I found a real solution that is hardware related. I was given a laptop with this exact same problem for free since my friend thought it wasn't worth paying to repair a 3 year old laptop, and was dead for almost a year (I think they manufactured these in 2008, but HP has almost no specs or info about them, specially ours; DV5T-1100) I have the solution to this problem, and is a solution not found almost anywhere using Google, and HP support doesn't want to tell you, simply don't know, or would make them look bad. I was able to fix it myself by using a rework station (basically a dedicated hot air gun) that I used to "reflow" the graphics chipset's connection to the board (keep reading, because this method may vary on result details). This simply means that I opened the laptop, removed the copper heatsink connected to the fan to expose both the micro-processor, and the faulty graphics chipset, and started cutting soda cans, or thick tin foil to cover the areas AROUND the graphics chipset, and leave the graphics chipset exposed so that the really hot air would concentrate only on TOP of the graphics chipset. Then, I put the device on 220 degress, with the tip of the gun 2 inches over the chipset, and circled the gun around heating that sucker for 5 minutes, then I did a 3 minute rest to cool off, and a final 5 minutes reheat again. Luckily enough it WORKED!, and it has been working for almost 10 months with heavy use. HOWEVER... doing a "reflow" like this on a micro component isn't reallt a proper fix. Sure you may get lucky, and I read of instances where the fix lasted for years, but also just months. This is because the problem is the old solder that connects each "ball" point under the chip to the motherboard may have a micro ultra tiny imperfections and misconnections on a few or many of the connected points cause by a long period of overheat of the chip due to both, a very bad heatsink, and heatflow of heat inside the laptop, and also (and usually) really bad maintenance on the user's part by having a really dirty and dusty vents, overuse, and blocking the ventilation exhaust of the laptop itself over time. A proper fix of this chip issue is another process called "reballing", where they actually properly overheat that particular chipset so much using IR heat, and an expensive machine, to "loosen" the solder of all connections and remove the chip itself to both, clean the old solder on the chip, and the old solder left on the motherboard, and actually REPLACE all solder with new lead solder. However, this process has to be very precise (hence the machine), and it maybe costly, and there's also the fact that MANY scammers out there either never really do a true reballing, ans just do a reflow to scam you, or don't have the experience to do a proper reball of the chip. So whose at fault here? Uneducated users that neglect learning how to properly maintain a laptop off its main enemies (dust and heat) no matter how good the hardware heatsinks may be, or is it poor hardware design by the manufacturer, where other brands or even other families of series off the same brand have actually better noticeable hardware design than these DV series that are so notorious to overheat easier than others out there? Well, I don't know, but I do know that you should be VERY careful having these laptops repaired and be scammed, because hey! Even so called "refurbished" or even so called "brand new" entire motherboard out there on Ebay are just bad reflow jobs with little to no warranty on them on purpose, to only last a few months on purpose. So, watch out, and THINK! before spending money on a beat up poor donkey.

Action "mode" in PSE5

Is there an "Actions" Palette in Photoshop Elements 5? I purchased this to be able to touch up my underwater photos. A book by a couple specifically mention this but is it only in the full photoshop? Also, I cannot find the Adobe Studio area on the website.
Thank you.

Thanks. This is what I figured after going through the main screen and the manual does not mention actions. But since latley manuals are pretty light, I thought I would ask.
The actions I was looking for was an easy fix for underwater photos. As you may knowm they are severely skewed to the blue especially for snorkelers who can't get down too deep and without a dedicated hot shoe flash. I use a Canon A70 and the flash is weak in this sitaution. I set the white balance as Canon suggests.
I have been using either histogram layers but I am a little weak on layers. What seems to work real well is to use auto level, then auto color correction and auto contrast. I guess that would be something similar to what an action would do anyway.
Thanks for the replies.

Building A CUCM lab with SNOM 710 IP Phones

Hi there, this is very basic but since I am just getting to know about IP telephony and CUCM, If any one can guide and help me with configurations and procedure for the following tasks,
I have downloaded a free demo copy of CUCM 8.6 which i intend to use in lab for practise purposes, I have got 4 SNOM 710 SIP Phones and a cisco 2960 switch to work with, i need to enable telephony between them and also enable all the features which I can.
My question is what steps should i do on CUCM after installing it as a VM on my Vmware workstation or else dedicating a spare server which I have , installing ESXi on it and then creating a CUCM VM.
What services and features I need to enable on cucm and how do i register these phones and users to enable calling.
What configuration do I need to do on the switch and the phones.
Is there any way that i can get a free copy of Unity connectcion to enable voicemail in the same environment.
Waiting for Help.
Thank you

Hi Shaik,
As far as I know , u require the licenses may be DEMO.
Since u have installed the CUCM, you can check the same under Call Manager Administration----System --licensing Report.
If phones are in same network with CUCM, you can assign static IP addresses or go for DHCP option assigning tftp option 150 with CUCM IP address.
else you can for Data and Voice VLAN config on the switch and do inter VLAN routing on L3 device.
regds,

The ideal hardware setup / arrangement for After Effects?

Hello there,
Looking to buy some new hardware and am hoping to find some advice on the ideal hardware config for making After Effects scream. I find this questions is sorely lacking answers on the Internet beyond the basics of 'boot from an SSD' and the like... So I am hoping someone can answer these questions once and for all.
Two things I am after:
1. Fast working performance in AE. So when I move a layer about I am able to see it move smoothly in real-time as I drag it about with my mouse. Right now I get either stuttered movement when moving larger layers about, or the image begins to pixelate/drop res to such a horrible extent that I can not see what I am doing. The problem extends to when I am working with a large project file, with many layers, I get nasty lag when attempting to move about in the timeline, opening comps, etc. Everything starts to move quite slowly once I go past a certain number of layers. What upgrades will speed this element, the day to day working rather than rendering, up the most?
2. Faster rendering. Though this is not as key as point number 1.
I am guessing this performance will he helped by a beefier graphics card and more/faster RAM? I currently have a GTX 660ti 2GB and am upgrading to a GTX980 4GB, so hoping that will improve this.
I also have 64 GB of 1600 speed ram that AE happily consumes so think that base is covered. My CPU is a 3930k that is slightly overclocked. It gets maxed out when multicore rendering is happening but not otherwise. I've heard turning hyperthreading off in the BIOS can actually help AE performance?
I am booting/running AE from an SSD (Samsung 840 Pro), and have set my media cache to another dedicated SSD (Samsung 840 Pro). I run/keep my project files on yet another SSD and have other drives holing media.
My drive config plan is this:
- Boot from one 240GB SSD.
- Project files and current working media on 2x 1TB SSDs in RAID 0 (backed up)
- Further media storage on 2x 3TB HDDs in RAID 0 (backed up)
Now I am wondering if I can simply use the 2TB of SSD goodness as both the location for my AE media cache AND my project files/working media? Or am I better off having three fast and seperate storage locations? 1 for the boot, 2 for the project files and media, 3 for the cache?
Otherwise I am running AE on a Hackintosh 3930k CPU overclocked slightly, 64 GB RAM, Sabertooth X79 mobo, 660ti graphics card.
All comments/advice links much appreciated. Apologies if this has already been addressed elsewhere but I have yet to find a detailed response and only generalized comments such as 'use a fast drive for your media cache.'
What I would really like to know is the BEST drive configuration, the questioned detailed above...And what will increase the speed and quality of my real-time workflow in AE the most. Quickly navigating projects without lag, opening detailed comps with many layers, and moving large images around without lag or pixelation.
Thank you!

for After Effects advice, Eric on the forum here can give you the best info. However, I have seen him say many times that AE is MEMORY INTENSIVE,....the more, the better. You HAVE 64GB...that seems very adequate for most workflows.
The OTHER thing he says is that other than Ray-Tracing, the GPU is HARDLY used at all.....CPU speed and number of cores are a BIG factor in AE performance.....your 3930k overclocked should be adequate....the MORE OC, the BETTER.
Next is the drive system....you have NOT described EXACTLY what you are doing NOW....you mentioned what your PLAN is,but for , right NOW you said : " I run/keep my project files on yet another SSD and have other drives holing media. "
HERE is where you MAY be doing something that may....or may NOT.....be causing slowdowns.   With AE it is RECOMMENDED to use a dedicated drive for the "Global Performance Cache"...the HIGHER the speed of this drive, the BETTER, as AE STORES already "rendered" frames, ( for "previews", of course), on it so it DOESN"T have to RE-RENDER ALL the frames all over again every time you make a change to your work !!! So, in YOUR case : your OS drive is great...Samsung Pro models are the BEST...you have the 840 Pro ,which is only SLIGHTLY behind the 850 Pro in performance. ANOTHER 840,or, 850 Pro would be GREAT as the " Global performance cache drive" AND would also be the place to put ALL previews,Cache files, media cache files for Premier Pro,too. The overall speed and less latency of the SATAIII SSD will surpass the performance of a 2 disk RAID 0....even a 3 disk RAID 0.
Next....the speed at which you SERVE UP the video files can be important in preventing a slowdown.....ESPECIALLY if using large, uncompressed files. Here, you have options.....it is NOT necessary to put your project files on a SEPARATE drive from your media...you just want to make sure that the drive with your media and project files is as fast as the OTHERS in your system ! SO, you COULD use a THIRD SSD as a "working drive" for ACTIVE projects only.....a 1TB SSD perhaps...Crucial M550 is CHEAPER than the Samsung and as good as the 840 pros. As the CAPACITY of SSDs are small...you would MOVE all media and completed project files to HDDs for archiving and storage....the use of RAID with your existing HDDs would NOT be needed for this function.
Another option would be to take FOUR quality 1TB HDDs...( the Seagates are selling for $44 right now), and create a RAID 0 off the motherboard to have a large 4TB capacity AND speed similar to the SSDs!   WARNING !!! the odds of ONE drive failing are BIG....you would immediately lose ALL your data !! HOWEVER....if you back up that RAID 0 RELIGIOUSLY....you would have NO worries. One way to do THAT is to buy a 4TB ENTERPRISE level 7200rpm HDD....Seagate has one with a 128 MB cache that does over 200MB/sec. for just over $300.
Even with all this covered, there are MANY factors which can CHOKE a fast computer....the CODECS you are using have a HUGE bearing on performance. The VERSION of After Effects is important...NEWEST versions have the BEST performance with features like the "global performance cache", etc. The use of "third party plug-ins" can CRIPPLE a machine if these are NOT written to take advantage of "hyperthreading",OR, are "32 bit" and HUMBLE your machine because AE is NOW 64 bit!!
Make sure you have Windows fully updated and the newest drivers for your video card. Then , make sure your Windows POWER SETTINGS are set to MAXIMUM PERFORMANCE when"plugged in"....the DEFAULT Windows settings...even under "high performance" has setttings that will THROTTLE your GPU and CPU if you don't change them.....I found THAT out the hard way!
Finally, make sure , in AE settings, you have set the"memory allocation" correctly...there is a formula regarding how much to assign on a "per CPU core basis". There ALSO is a selection to make for "allowing multiple frames" to be processed...make sure THAT is set correctly.
Good luck !!     I hope this helps!

Raid- Understanding "Hot Spare" and Windows reinstall - Final Steps

Hello all,
If you follow couple of my other recent threads here you will see I have a warning of a failing drive in my 4 tb raid (4 x 1TB raid set.)
Also for an unrelated reason I am also needing to reinstall Windows 7. (and of course my Adobe Master collection CS5)
I ordered a 5th drive to serve as "Hot Spare" and it will be arriving sometime today from Amazon.
I want to make sure I do the above "final steps" properly, in the correct order.
I am basing my "final steps" based on Harm's advice on another thread:
>>>
You can never be too safe with data, but if you follow the hot-spare, extend raid set and rebuild sequence, it is not necessary. Your data will be reconsructed automatically. That is the reason you use a raid3/5.
Your log file is a definite show of a serious disk problem. Replace it, create a hot-spare, extend your raid set and rebuild (it should be done automatically) and you are ready to roll
>>>>
(As a precaution I have done a backup of my raid, to an external drive)
So once my new hard drive arrives today from Amazon, I will, in the following order:
1) Replace failing hard drive. (Do I need to power down the computer to remove the failing hard drive and replace it with the hot spare? Or can I leave the computer powered on so that the raid software can continue its CONSISTANCY CHECK while II do all of the steps to rebuild the raid --- see note at bottom of this post...)
2) Create hot-spare
3) Use the Raid controller software (Areca) to EXTEND HOT SPARE
4) Rebuild raid (it should be done automatically)
THEN, after I confirm that the raid is working okay, I will
5) Reinstall Windows 7.
THe below step is what I am not entirely clear on:
6) I assume since the raid has already been rebuilt {before I did the windows 7 reinstall) I can do a very straightforward "reconnect" to the already working raid. In other words, I would reinstall the Areca raid software (using the Areca cd) and identify the raid and windows 7 will recognize the 4 tb raid as my raid drive.
I am tracking the delivery of my new hard drive and it is at least 5 or 6 hours away from arriving from Amazon.
**** CONSISTANCY NOTE: I the meantime I am having the Areca web based controller software do a CONSISTANCY check of the raid.
It is half way through the check and has found 144 errors so far. The consistancy check is rather vague about what it is doing. But can I assume that it is finding the errors and will automatically fix them.
Or do I have to do something to fix the errors once the consistancy check is finished (This is one reason why I would like to avoid powering down during the rebuilding of the raid.) Or will creating the hot spare, etc interrupt the consistancy check, meaning I must finish the consistancy check completley before rebuilding the raid.
Or should I abort the consistancy check and do that after I reinstall windows. (If possible I would like to do that so I can get on with the editing of my current project!!)
WHEW!

6.6.5 Check Volume Set
To check a volume set from a RAID set:
(1). Click on the “Check Volume Set” link.
(2). Click on the volume set from the list that you wish to check.
Tick on “Confirm The Operation” and click on the “Submit” button.
Use this option to verify the correctness of the redundant data in
a volume set. For example, in a system with dedicated parity, volume
set check means computing the parity of the data disk drives
and comparing the results to the contents of the dedicated parity
disk drive. The checking percentage can also be viewed by clicking
on “RAID Set Hierarchy” in the main menu.
Directly from the Areca 1600 series Manual. I would let that finish.

Where is hot spare status "stand by(5)"? Using "raidctl" command we get these lines:
head1 > raidctl get type=lsi target=profile ctlr=0
........<cut>...........
Total hot spare drives: 1
Standby: 1
In use: 0
........<cut>...........
Why SNMP can't get hot spare status? Where to report this issue? Thanks in advice.
Nerijus

Thanks.
To answer your question, the disk FW upgrade doesn't erase/destroy the data. However the disk FW upgrade can ONLY be done while there is NO IO activity, hence you need to stop the IO before proceeding with such upgrade.
As for the FW, it seems that your drive has the FW 0892 which is a newer FW than what your CAM version has (0791). The FW 0891 was supported with CAM 6.0 + patches. Starting from CAM 6.1.0_15 we introduced the FW 0B92.
The recommendation is to upgrade CAM to 6.4.1, then you will get an alarm because your drive will have 0892 whereas CAM brings 0B92, however you can plan a maintenance window at your convenience in order to upgrade the drive FW.

When to replace drives, and when does the hot-spare kick in?

Here's the situation: got an e-mail today from the RAID (no it wasn't a love letter), which alerted me to a ten-times repeated ERROR: 0x10, STATUS: 0x51 on drive 8
I then proceded to check through the log, and found from a while back (mysteriously I never received an e-mail even though it said it had sent one!) ERROR: 0x40, STATUS: 0x51
which were however only single/double incidents, not repeated 10 times like this latest error.
Despite these errors, the drives show up as "OK" in RAID Admin, and the hot spare drives seem not to have been activated.
The question is now, should I get these drives replaced ASAP, or if the RAID lists the drives as OK is everything fine and dandy? (not sure how to take a "non-recoverable error 0x40" and reconcile that with a drive status of OK)

Nobody's got any answers? Bummer! The Apple manual says really nothing useful about how to aAsSsSeEsSsS error messages and when to replace drives, etc.
It's nice to sell to people that a RAID-5 will keep the data safe, but that only works if one knows what to make of the error messages.
I shouldn't have to spend another $1k for a tech support contract, just to learn what things mean that should be explained in the tech docs...

PS: will someone tell Apple's PC watchdog that aAsSsSeEsSsS has nothing to do with aAsSsS? AaSsSsEeSsSsMmEeNnTt is a technical term, yet it wouldn't want to let me post the message because it contained aAsSsSeEsSsS! What's next? Soon we can't use the word RAID anymore, because it's refers to undesirable violence...
Someone please pick up a dictionary, in Tiger there's both a regular app and a widget to do so, so it shouldn't be that hard...

300 GB disk as hot spare for 146 gb disk in stk 6140

Hi,
Does any body know this for sure?
Customer plans to buy new tray with 300 gb fc disks.
Also hey have old tray with 146 gb disks.
They want to assign two 300 gb disks as hot spares for old 146 gb and for new 300gb disks.
Will it work?
If you can confirm that this works, does this depends on firmware revision or CAM version or something else?
Thanks in advance!

I have not seen this work but It's my understanding that hot spares are "array spares" and that a larger drive can be a spare for a smaller drive.

MD3200i Shutdown with a Hot Spare in operation

I have to shutdown our MD3200 to make some network modifications tied- iSCSI and vCenter (replacing a switch)
One of the MD3200 drives failed and the hot spare is being used (RAID 5).
Is it safe to bring down the Md3200 while the hot spare is in operation ?
thanks

Hello SJNAPL,
If the drive failed a few months back then it has most likely been copied to the hotspare. You should be able to use MDSM & go to the Physical Tab & select the hotspare drive & it will list the drive that it is covering.
Once you get your replacement drive and insert it into your MD3200i the MD will sense the drive & should start the copy back to the replacement drive. Now the time that it will take is hard to say as it depends on the size of the drive and how much activity is on the virtual disk.
Once the replacement disk has the data from the hotspare then the hotspare should go back to being a hotspare drive again & you can view this also in the summary window of MDSM& the Physical Tab as well.
Please let us know if you have any other questions.

Why is hot spare in use while disk state is Okay

In my Solaris 10 RAID-5 volume, metastat shows the hot spare in use, but all the disks' state is Okay. Why is this? I do suspect the first disk was bad at one time, and may have been pulled out and re-inserted in without issuing any solaris commands. Please help explain why, and how to recover from this situation. Thanks.

Thanks for the suggestion. Tried "metahs -e ...". "Hotspare isn't broken, can't enable".
Tried "metareplace -e ...", "d10: device ... enabled" It's currently in sync'ing mode. I guess drive 380 was pulled out and reinserted at one point without issuing the metareplace command.
