Back up Server to new Raid 5 Configuration

I have recently had my drive fail on my server, luckly I back it up everynight. I decided to upgrade to a Raid 5 system, so got myself a 256gb Samsung Pro drive as the main drive, and 2 500gb Toshiba drives for the raid system. I set up the raid in my Bios,
and all seemed good, backed up the image I had stored, and no errors, but when booting the screen goes black, and just reboots. I thought iit must be something to do with the Raid config, so went back to the original setup, installed the image directly to
the ssd and it worked fine.
so, my question is, what do I need to do to get the backup to work on the Raid config, as I need to get this working.
Thanks in advance...

So you are trying to do a restore of an Image to a new set of disks.
1 disk is a 256gb and there are 2 500gb drives?
What is the raid configuration? (RAID 0, 1, 5)
When you restore the image, which disk are you restoring to?
After the restore, at what point does it reboot?
Is the BIOS set to boot from the Raid Controller?

But I verified the admin ID does have full access to the folders. furthermore it belongs administrators, domain Admins, enterprise admins,
What gives? what additional privilege I need to give to the login ID, I tried in vain adding to Virtual machines but got rejected. I also could not locate anything like virtual machines in the active directory,
Btw I finally managed to create a new VM wi/ VHD but still can't create new vhd

These actions are not performed in the security context of the user. The Local System / computer account of the Hyper-V Server is what needs the access, not the user.
Also, many AV products will cause these problems if the exclusions are not set properly, as they block the hypervisor from doing its job.

Send the Configuration via TFTP server to New Router/Switch

Dears,
I need to apply a policy that for any new router or switch installation, specific configuration will be sent to these devices through one centralized TFTP server which comply with our configuration and rules, this is to avoid any miss configuration from the team and control the junior network Engineer to add any wrong configuration that can effect the network, is this possible? And how?

Hi,
I dont think is there any mechanism but yes to secure you can configure on router that tftp source interface for tftp server cofniguration upload and download into router or on server.

HT4313 once it has rebooted and entered the installation, i get the message "it cannot be installed on this computer", i have created a new Raid Set, ive zeroed out the disks, only 10.6 or 10.5 server is allowed

I can see the restart button mentioned, but i cant get past the message that it cant be installed when it has booted up with the 10.6.4 server installation disc.
So far:
Copied installation cd to a hard drive and booted from it.
Created new raid set (RAID 5)
Zeroed out information on disks
10.5 server had no trouble installing
10.6 sl had no trouble installing
I used to have 10.6 server installed on the intended mac pro.
However i need to reinstall and it is not possible.
Any help would be very much appreciated

Where did you get the 10.6.4 install disk? Did it come with some other machine?
I ask because it sounds like that's the case - and it may only work with the machine (or, at least, model) it was shipped with.
However, if you have another 10.6 Server install disk, even an older version, just go with that and run Software Update after it's installed. The chances are you don't really want 10.6.4 anyway, right, but something later.

Clear RAID card configuration!

Hello All-
Thank you in advance for your help. I have a Mac Pro (8 Core (2.93), 16GB ram) and I have a RAID card with 4x1TB hard drives that I am trying to put into a RAID 5. The computer fell asleep when building the RIAD off the OS X live disk and became completely unresponsive. I let it sit for a few days, and finally decided to start over.
I tried running the Delete RAID option on the RAID Utility, but after a few days of letting that sit, it does not seem to be doing anything.
I have pulled all the drives, removed their partition tables and formated, but when I put the drives back in, the RAID card still sees the RAID array.
Is there a way that I can reset the RAID card? Or am I missing a step?
Any ideas would help. Thank you very much!

For those of you who find this topic in search of a solution to the same problem, here is my latest achievement. I too played the waiting game of nearly 48 hours waiting for my 4 1TB drives to complete the transition from the factory single drive RAID setup to RAID 5 (just got this MacPro last week). I then couldn't cancel it and when booting to the OS disk as am able to in all my other server RAID configurations, the system pretty much locks up on disk retrieves.
My next thought was to delete the RAID set, that too sat for an hour and I finally decided to kill the power and start over. I booted to the DVD again but this time I had removed all 4 drives from the RAID card. No RAID configurations came up in RAID utility so I plugged one back in (hot swap, right? right.) and it showed up. I created a RAID set with it only, wiped the RAID configuration information off it by creating this new RAID set and when it was done creating the new set, I deleted it. I then plugged drive 2, 3 and 4 completing the same process for each. Once all 4 drives were back in the system and the back migration configuration was removed, I created a new RAID 5 set and it was done in less than a minute. So, this was going really well and I created a new Volume. It is running now and hopefully will complete by morning (about 10 hours from now). I'll post back once it is done, but hopefully the information thus far may help someone who has a corrupted RAID set to easily remove it and start over. I won't have my system boot back up with data in tact, but this is a fresh install and that was not important to me now. If I had imaged the server either by means of TimeMachine or disk image, then restoring it would be the next step.
Good luck!
Rob

Why Doesnt the Time Capsule show up my New Raid Setup External HD?

I purchased a new enclosure for a RAID 1 setup (2, 1TB hard drives) and plugged it into my MacBook PRO to use disk utility to set up. The setup was fine. I then plugged this unit into the Time Capsule UBS port and it shows up on the airport application (2, 923gb drives) but does NOT show up on the network - which is what I want it to do. I know the USB port on the TC works because I have a small portable hard drive, plug that in and it shows up. I then unplug it, plug in the RAID and it does not show up on the network but does show up on the airport application.
I hope someone can help me with this.

PS: I have a second question about partitioning this RAID 1 set up but not sure if this is the correct place to pose that question. basically, I want to partition this RAID 1 into 3 partitions; one for Time Machine, one for superduper clone image, and one for misc. extra space. Perhaps you can guide me on where to post this question.

Anytime you change networking hardware, it is always a good idea to perform a complete power recycle of your networking components.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

RAID Level Configuration Best Practices

Hi Guys ,
We are building new Virtual environment for SQL Server and have to define RAID level configuration for SQL Server setup.
Please share your thoughts for RAID configuration for SQL data, log , temppdb, Backup files .
Files RAID Level
SQL Data File -->
SQL Log Files-->
Tempdb Data-->
Tempdb log-->
Backup files--> .
Any other configuration best practices are more then welcome .
Like Memory Setting at OS level , LUN Settings.
Best practices to configure SQL Server in Hyper-V with clustering.
Thank you
Please Mark As Answer if it is helpful. \\Aim To Inspire Rather to Teach A.Shah

Hi,
If you can shed some bucks you should go for RAID 10 for all files. Also as a best practice keeping database log and data files on different physical drive would give optimum performance. Tempdb can be placed with data file or on a different drive as per
usage. Its always good to use dedicated drive for tempdb
For memory setting.Please refer
This link for setting max server memory
You should monitor SQL server memory usage using below counters taken from
this Link
SQLServer:Buffer Manager--Buffer Cache hit ratio(BCHR): IIf your BCHR is high 90 to 100 Then it points to fact that You don't have memory pressure. Keep in mind that suppose somebody runs a query which request large amount of pages in that
case momentarily BCHR might come down to 60 or 70 may be less but that does not means it is a memory pressure it means your query requires large memory and will take it. After that query completes you will see BCHR risiing again
SQLServer:Buffer Manager--Page Life Expectancy(PLE): PLE shows for how long page remain in buffer pool. The longer it stays the better it is. Its common misconception to take 300 as a baseline for PLE. But it is not,I read it from
Jonathan Kehayias book( troubleshooting SQL Server) that this value was baseline when SQL Server was of 2000 version and max RAM one could see was from 4-6 G. Now with 200G or RAM coming into picture this value is not correct. He also gave the formula( tentative)
how to calculate it. Take the base counter value of 300 presented by most resources, and then determine a multiple of this value based on the configured buffer cache size, which is the 'max server memory' sp_ configure option in SQL Server, divided by 4 GB.
So, for a server with 32 GB allocated to the buffer pool, the PLE value should be at least (32/4)*300 = 2400. So far this has done good to me so I would recommend you to use it.
SQLServer:Buffer Manager--CheckpointPages/sec: Checkpoint pages /sec counter is important to know about memory pressure because if buffer cache is low then lots of new pages needs to be brought into and flushed out from buffer pool,
due to load checkpoint's work will increase and will start flushing out dirty pages very frequently. If this counter is high then your SQL Server buffer pool is not able to cope up with requests coming and we need to increase it by increasing buffer pool memory
or by increasing physical RAM and then making adequate changes in Buffer pool size. Technically this value should be low if you are looking at line graph in perfmon this value should always touch base for stable system.
SQLServer:Buffer Manager--Freepages: This value should not be less you always want to see high value for it.
SQLServer:Memory Manager--Memory Grants Pending: If you see memory grants pending in buffer pool your server is facing SQL Server memory crunch and increasing memory would be a good idea. For memory grants please read this article:
http://blogs.msdn.com/b/sqlqueryprocessing/archive/2010/02/16/understanding-sql-server-memory-grant.aspx
SQLServer:memory Manager--Target Server Memory: This is amount of memory SQL Server is trying to acquire.
SQLServer:memory Manager--Total Server memory This is current memory SQL Server has acquired.
For other settings I would like you to discuss with vendor. Storage questions IMO should be directed to Vendor.

About Raid 5 Configuration

Hi Sir,
Can You Please explain What is RAID-5 Configuration ??
What are the features of RAID 5 Configuration & Advantages of
RAID-5 Configuration.
Operating System is Windows NT.
We had Compaq Server, it has 3 Harddisk, if we remove 1 of the
harddisk which is not of Boot Sector, What will be happened
after removal of one of the harddisk ??
Please guide us,
Thanks.

Thanks so much, Camelot!
It didn't work at first, but it helped guide me to Google the right info.
I filled in the blanks with info I found here:
http://www.macosxhints.com/article.php?story=20080531040605723
In case others should come across this posting, here's what I did:
disktuil info /Volumes/RAID5
(to get the UUID)
vifs
then append:
UUID=63E14BC4-25D1-3140-B146-64B4CC4E7C28 /Users hfs rw 1 0
(Note: The lines ends with "hfs rw 1 0" instead of "hfs,rw")
vi /Library/Preferences/SystemConfiguration/autodiskmount.plist
(this was a new file)
and include the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>AutomountDisksWithoutUserLogin</key>
<true/>
</dict>
</plist>
If autodiskmount.plist already has some settings, make certain the AutomountDisksWithoutUserLogin key is <true/>
In my particular case, I had to rm my /Users symbolic link and mkdir /Users again.
Finally, restart.
Thanks again!

S20 *new* RAID config for retail Windows 7 install...questions

I’ve recently ordered a S20 and I have a few questions about my situation/configuration, if anyone has the knowledge and time, I'd really appreciate it.
I’ve configured the workstation to be shipped without an installed OS, a single SATA hard drive, and no optical drive. I have a new retail copy of Windows 7 Professional that I will install, two Seagate 1TB SATA hard drives that I will install in RAID1 configuration, and a new DVD multi-recorder ready to install. The drive that comes with the workstation will be used as well, but not as the boot drive. I wish to boot off of a partition on the RAID1 set.
I’ve looked into the hardware/user guides for as much information as I could find, but I’m not clear, and thus concerned, as to what I will need to do to get RAID setup with a boot partition and install Windows.
I see that there are three SATA ports for hard drives on the main board.
1) Can RAID be configured using ANY combination of these ports, and is the unused port still available for normal SATA drive hosting?
For instance, can I configure two 1TB hard drives on the first two ports and configure a third non-RAID drive on the third port?
I am now familiar with the BIOS RAID configuration utility from reading the guides.
2) How do I install an OS (Windows 7 32 or 64) on a new RAID partition, once it is configured, if my retail version of Windows doesn't have the driver?
For instance, can I provide the driver during installation via the Windows 7 setup?
I understand that there are also two SATA ports for optical drives on a separate controller (for five SATA ports total).
3) If I attach my DVD drive to one of the SATA ports intended for optical devices, will the system see it as a bootable device?
I need to make my DVD drive a boot device in order to install windows, so I'm hoping that the system will see it that way. I also hope that the SATA ports are labeled on the main board! (Optical 0, 1 / Disk 0, 1, 2) ???
If anyone has the time to help me with these three questions I think I will be more at ease. I worry about going off the path and ordering a blank machine, but I am adamant about a non-OEM OS.
BTW, I am moving to the S20 from a five year old IntelliStation M Pro which is the best machine I've owned so far. I also keep a ThinkPad X61 at my side. Really looking forward to the new workstation!
Cheers!

erik, thank you so much.
I was thrown off by the Marvell driver in the S20 download page, I think. Now I'm ready to go.
Come on Lenovo...

Kernel Panic when using a new RAID 5 array

I recently set up a new Sans Digital 5 disk 7.2TB hardware RAID 5 array that's connected to a Sonnet Tempo-X eSATA 4+4 PCI-X card which has been updated to the latest drivers. The same card supports a number of JBOD enclosures that run as mirrored RAIDs under SoftRAID 4.0. My system is a 2.7Ghz DP Tower.
Upon trying to copy to the new RAID 5 volume I encountered a kernel panic and system freeze complete with wailing fans. After a few system restarts and a call to Sans Digital I tried to connect the RAID via USB upon the recommendation of tech support. Rather than causing a crash while copying I received an error message in the copy progress window that said that some files were locked and the process could not be completed and the RAID was no longer mounted in the finder.
I called Sans Digital back and they said it was probably a defective enclosure. I have just received a new one and have put that into service. All seemed fine until, when I was 30GB into a 900GB copy, the system froze. I have also tried to copy fewer files (400GB) and still get a Panic. When the RAID is idle there does not seem to be a problem. The last time the problem occurred the copy progress bar hung but the system did not fully lock up. The LEDs on the front panel of the RAID enclosure were flickering rapidly but no data was copying from my other drive. I turned off the RAID and was able to use my mouse again and restart my machine with a normal restart.
My system is running OS 10.5.8. When the RAID is off my computer runs fine.
Not sure what to try next. Any help would be appreciated - Thank you.

Hi-
I'd be interested to know if Sonnet has any comments regarding the issue.
In Utilities/Console/Logs, there should be some indication of what is occurring when the crashes occur.

I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device. But I have a Conceptronic router. Will Time Capsule work with this and how?

I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device. But I have a Conceptronic router.
1. Will Time Capsule work with this and how?
2. Can my printer USB be plugged in and then shared between the devices?
3. Can I create a network and how?
4. What happend when a visitor logs onto my existing wireless router?
I'm new to Macs (well a returning user having started with Mac Plus!!) and not very technical. Any help / advice will be much appreciated.
Ray

The key to what you seem to want to do is to be able to get Apple's Time Capsule router to "join" the network that your Conceptronic router. I believe that works with some third-party routers, but I've never seen a list of those that work in such a configuration and I have no experience with Conceptronic equipment.
You might be better off with a Network-Attached Storage (NAS) device instead of a Time Capsule.

K8N DIAMOND: New Raid array and old HD... I'm going crazy!!! Please

Hi guys
First, sorry for my poor english...
My problem is:
I bought two Raptor 36 Gb for my new raid array.
I have my old HD Hitachi 250 Gb connected on sata 1.
I connected my two raptor, on sata 3 and 4, I enabled all sata port and raid config for ports 3 and 4.
I restart PC, typed F10 and set a stripe array with two raptor. All run ok...
Restarted and boot with my copy of WinXP with SP2 and NF4 raid drivers.
Installation found my array and my Hitachi;
Hitachi with 4 partitions; C (os), D (driver), E (films), F (music)
I create one partitions on my raid array, and it takes I: letter... So I formatted and start to copy os...
Errors occurs when, restarting pc and resetting the boot to Hard disk (the order of booting is 1 - nvidia array, 2 - hitachi 250 gb), just before loading installation, It shows a black screen with an error: "there is an error in your hard disk bla bla bla.. try to control your connection or connect to windows help....bla bla..."
The Raid array works properly, infact I try to disconnect my Hitachi from sata port 1 and all installation works (I'm writing from Win xp on the raid array).
I tried to connect the hitachi on port 1 of silicon image controller.... same error..!!
I'm desperate... I have all my life on my hitachi...
I think that there's a sort of conflict in drive letter assignement... I cant find a solution ..
PLEASE HELP ME!!!

Glad it worked, I had a feeling it would.

One question for you.. on G: partition, there's a directory called "Windows", do you suggest me to format this partition??
You can format it if you want to free up space, but unless you moved things around the My documents folder and everything in it is on that partition, along with anything you might of had on the old desktop during that Windows install. You might have something you want there, I usually leave mine for a few month, and figure out if I have everything I need.
Quote
What I have to do, if I need to reinstall WIn XP on first partition of raptor array??
Things should be fine now as Windows marked the Hitachi drive as G. You should be able to reinstall without issue. But if you have a lot of sensitive info on the Hitachi, I would always disconnect the Hitachi if doing a fresh install. Once windows is done installing, hook it back up. But next time you shouldn't have to reconfigure NVRAID after disconnecting and reconnecting.

P2V of a Dell Windows server with HW Raid

Hi,
I've got a few very large WIndows 2003 Dell Servers to Virtualize. The problem I've got is that each of the Dell Servers has a hardware raid configured (using the device driver mraid.sys). If I perform a standard P2V of the Dell Server the Windows image fails to boot because it cannot find the 'C:\' Drive. To overcome this I pefromed a Linux DD of the Dell Server to an 'intermediate' standalone server that doesn't use a raid controller (standard SATA HDD), peformed a Windows repair and then did a P2V from this 'intermediate' standalone server to create the VM Image.
I don't want to modify the original Dell Server (the one with the HW Raid controller), just incase the P2V doesn't work.
Q: Can anyone suggest a better way of pefroming a P2V on a Windows Server that has a HW Raid controller (the device driver is the problem here).
BTW the P2V 'sees' the HDA Partition of the Dell Server. Alternatively is there a way to 'remove' the device driver mraid.sys and repair the VM Image?
TIA

If you have a My Oracle account (support) take a look at KB article 1122170.1
This is an article that addresses the same problem after virtualizing a HP server (hard ware raid). It has something to do with the MBR placement.
