Ix4-300d: JBOD expandable without rebuilding volume / data loss

In the german Lenovo forum there is the following questiion, which I can not answer:
Assuming an ix4-300d filled with 1,2, or 3 drives as JBOD (no Raid). Can it be expanded by adding other blank drives without the need to start from scratc, to say loosing all data because of rebuilding the volume.
'just plug in empty drive, reboot and let it run'

Hello wolliballa,
I still highly recommend backing up critical data before doing any RAID migrations or expanding an array just in case something goes wrong in the process.
With the ix4-300d, you can expand a NONE ( JBOD ) array to newly added disks without wiping data. To do this, you would navigate to the "drive management" page in the web interface after booting the unit with the added drive(s), then click on "settings" at the top of the drive management page. Within the drive management >settings page you should see a "add disks to existing storage system" check box. If you check that option all new disks would be added to the existing JBOD array.

Ix4-300d JBOD as truly independent disks

When I first bought the ix4-300d, I instlaled just one drive. I just tried installing a second drive, but I cannot get the two drives to show up as two truly independent drives, just one volume. I want to choose the drive in whch I can store the data on. It doesn't look like this is possible. Can the firmware be upgraded to have this ability?

I would not put too much hope on this.
As far as I have seen the ix4 -series never has been designed for supporting more than one volume ( either JBOD or Raid). You could try with iSCSI-Configurations, but I never have seen that alive yet.

IX4-300D - Raid rebuild stuck?

Hi,
When I arrived this morning at work I found that my NAS (IX4-300D) was doing a RAID Rebuild
I can ping the NAS but I can't access via web interface, storage manager or SSH.
I tried pressing the "Display control buttons" to try to see some info, but i'm stuck at the massage "Support access is enabled" since I add SSH enabled, the dipslay only shows that message.
The problem is that I don't now if the raid rebuid is working, if its going to take long, or if its simply stuck.
Can I hard reboot ths NAS? Should I wait longer?
The rebuild is going for more then 1h30min but I can't be shure because it may as well started during the night.
I did not received any drive error massage.
The NAS has 4 drives with RAID 5 setup.
Can you please give me some light of what to do next?
UPDATE: After +1h or so the Disk Activity led stopped (it was flashing before) but the System Status led is still flashing.
Thank you

Thanks for the response.
I've been exchaging email with someone of the suporte team.
I hade to turn off the NAS, after booting everything seams OK, although I havent check all the data.
The suport asked me to send them a dump files, but i'm not been able to get it, its takes a long time and i've lost the session a couple of times.
I tried to keep the session opened by using the web interface from time to time, and after 2hours it was still processing the file, had to left work so don't know if in the meanwhile the file was created, but i dont think so.
I've sent them another email, but since its the weekend I will probably only get an answer next monday.
Meawhile if I can get this questions answered it woul be great:
I notice that the system only has 42mb on "/" could it be a problem?
Where does the dump file goes? Can it be genarated by terminal?
Thanks

Lenovo ix4-300d - Data protection is being reconstructed gets stuck.

Hi experts,
After a power loss my Lenovo IX4-300d went on a "Data protection is being reconstructed" phase. This process never ends because it gets stuck at a certain % that changes every time I power on the IX4, at this point it becomes unresponsive and I have to unplug the power cord. I´m using RAID 5, so theoretically there is more than one drive failing. I am not an expert of course, just googled this, I don´t even know if its right.
In the other hand there is nothing stating a HD failure in the logs or the system status of the IX4.
So, how can I identify which drivers are failing in order to replace them?
Could this be a logical failure and be fixed by formatting the drives?
Any additional comments or recommendation? I am able to access my data while it´s "reconstructing" so I am moving my things out of the nas.
Thanks
EG

You can try rebooting with one drive removed at a time. If you are having one drive fail you should be able to boot with it missing. You should also check to see if you are still in warranty and call tech support. They will be able to assist in diagnosing the issue and replacing drives if needed.

Ix4-300d iSCSI disconnect Windows 2012R2

Hello Everyone,
I just recently purchased (3 days ago) an ix4-300D and updated it to the latest patch. I have 4 x WD 3TB Disks and they are configured with a raid 0 configuration. I then have 2 NICs (not bonded) and using the second port for the iSCSI LAN (192.168.100.100, Jumbo Frames 9000) and the 1st port for accessing the device (192.168.1.100). I carve out 3 TB iSCSI LUN (with CHAP) and give it a name. My Windows Server sees this (under the 192.168.100.X network) and I"m able to bring it online, mount it, format it and use the LUN. I then start copying about 2.5 TB of Data off an ix2 back to this Ix4 and about 1/4 through the copy, the iSCSI disconnects and the actual unit is frozen., It won't respond to web interface on the 192.168.1.x LAN either. I have to actually unplug it and then plug it back in for the unit to respond. I know that iSCSI works on the Window Server as I replaced a custom NAS Server using OpenFiler and worked for over 2 years w/o issues/reboots or anything else. The only thing that has changed is the NAS box (the ix4-300d). Can anyone think of anything I could be doing wrong? What to check? I am thinking it is a bad unit but I want to check everything first.
I will say the only thing that *could* be out of line (but is VERY doubtful is the problem) is that 3 of the WD drives are 3TB Reds and 1 is a 3 TB Black. I'm going to remove the black drive and redo the entire unit to see if that resolves the problem but I doubt it will. I know the Reds are "certified".
I have already removed the Jumbo Frames just in case (though the windows networking card supports Jumbo Frames 9000 since the old SAN was working with these w/o issue).
Thoughts anyone???

Hello CPXGreg
Using a mixed disk array can cause instabilities, so I do recommend that you try using the unit without the WD Black disk for at least testing.
Next, there are various factors that could cause or contribute to a firmware lock like this. Usually this is caused by media server crashing, which then escalates to a full firmware lock. I recommend checking that media server has been turned off for now and any unused protocols. If the unit still locks up I recommend that you contact LenovoEMC support to have a dump report from the unit reviewed. This way we can check what may be at the root of the issue.

Upgrading HDs on ix4-300D

Hi there, I have a ix4-300D with 4 x 2Tb HD on R5, I would like to know if there is a procedure to upgrade the hard drives to new ones of more capacity without loosing the actual configured raid, I mean, not needing to pivot the data, and if this procedure exists, how safe it would be. One way or another, I want to upgrade to 4 x WD60EFRX or WD50EFRX, are those drives supported ? do I need any firmware upgrade? thanks

Hello lean296
The WD50EFRX 5TB disks can be used on the ix4-300d, see the updated approved drive list here. You would need to be at least running a 4.x.x firmware, it is highly recommended to be using a 4.1.x firmware though.
As for the upgrade process, you technically can replace one disk at a time an allow the unit to boot and reconstruct after every disk replacement, however this will only use your previous disk's capacity. To be able to utilize the full capacity of the new disks you should follow this guide and backup/copy your data before begining.

Lenovo ix4-300d and 4 Hd 6 tb red

Hi first of all sorry for my english,
I have 4 Nas ix4-300d,
3 with 4 green 3 tb Hd they work perfectly never have any problem in 3 year. I work in raid 0 because
I duplicate the files in other HH and I want the maximum of space available.
the fourt one I bought 3 days ago and I try to install 4 6Tb red wd inside it in Raid0 here is the problem...
I can't create shares becouse of this message :
"The selected function is not available due to the state of the pools"
So I look on the internet and see that maybe I can't work in raid0 if the disk is bigger than 4 TB (CRAP)
then I try to put Raid 5 ( the only I can choose beside Raid 10 ) but in 36 Hours the data recostruction
is only 19 % with 0 files on it.......................
Can someone Help me please?
Can someone give me some advise?
Did you know a Nas that work in Raid0 with 6tb and 8 tb disk?
Ty in advance.

Hello Nico84
1. The ix4-300d will probably be able to use 6 TB HDD's if only 2-3 were installed and depending on the protection mode( 2x 6TB disks RAID 0, 3x 6TB disks RAID 5). However the limitation your are running into is that the the ix4-300d's Marvell Armada XP 1.3GHz MV78230 processor is only 32 bit and has the 16 TB ceiling.
2. The ix2-dl and px class devices can officially support 6TB HDD's in RAID 0 or NONE.
3. Please check with these retailers/resellers about lenovoEMC devices in your region. Where to Buy
4. With any 32 bit system the capacity limit for a volume is 16 TB. With the ix4-300d the max supported is 4x 5TB disks in RAID 5, this would roughly yield a 15 TB volume.
What you are attempting with the 4x 6TB HDD's in RAID 5 would roughly yield a 18 TB volume, which is above the 16 TB volume ceiliing for the unit's processor.
Again using 3x 6TB HDD's should theoretically work in RAID 5 and yield about a 12TB volume. If you were to use just 2x 6TB HDD you should theoretically be able to have a 12TB RAID 0 array. Both of which would be under the 16 TB cap.
If you are fully intending on using 4x 6TB or larger disks, then a px class unit will need to be used.
I hope this better explains the situation you are having.

Ix4-300d addiing hdd issue

Hi!
I started off with 3x3tb in RAID5 and now upgraded with a 4th disk of the same model. Extension went smoothly, and I see the new size in the Drive Management (as well as the header bar), however the shares still report the old size. Already tried rebooting but didnt bring the expected success
My guess is that some storage pool would need extending, but I didnt find any such option anywhere. Any help appreciated

Ix4-300d stuck at 75% boot

I had to move the nas box to a different room during the intial 5 RAID initialization, and the ix4-300d didn't appear to like that. Since I had no data on the box I went ahead and "clean" the disks using the instructions in the knowledge base, and attempt to set it up a second but it is still stuck at the 75% boot percentage.
It has aquired an IP address on my network, and is pingable but the webpage isn't working, and the only port that is open when I ran a port scanner against the ip address is port 111.
Is the internal operating system stored on internal flash, or the SATA disks in the bring your own disk model?
Solved!
Go to Solution.

Hello Stonedturtle
Are you having this issue on a ix4-300d unit? If you are, please check/try the following. If this is regarding the px6 unit on your other thread, please follow the instructions I left on that thread.
Power down the unit, re-seat all disks that are in the unit, power back on.
If the unit continues to hang @75% for more than 5-10 minutes, it could be one or more of the hard disks causing the process to halt. Try booting the unit without disks to see if the " device not ready..." message appears on the LCD and web UI.
If the unit can boot on it's own, try insering disk #4 into bay #1 and disk #1 into bay #4, leave disk 2 and 3 in the same bays while powered off and then try booting again.
If the unit does not boot on it's own without disks, please contact LenovoEMC support in your region about a firmware imager.

Migrate from Raid 1 to Raid 5 with IX4-300D

I am considering to buy a IX4-300D.
But what I would like to know: I might consider starting up with 2 drives in RAID-1, and later down the road buy a 3rd drive to upgrade my to RAID-5.
Can this be done on the fly, meaning I can just put in the 3rd drive, and I can upgrade to RAID-5 without data loss?
(Yes, I should certainly have a backup before doing that, but I would like to get around to create a new RAID-5 and having to copy back the data from the backup)
And will I be able to upgrade my 3 drive RAID-5 later to 4 drives?
Solved!

Have not tried / seen this yet. All lenovo pieces with raid 5 had 4 disks in, although theoretically it would work with 3, see http://en.wikipedia.org/wiki/RAID

Migration from PC to Mac without losing application data (savegames etc.)

Hello everyone,
I am migrating from from my old Windows PC onto a MacBook Pro, and I'm having difficulties with iTunes and my iOS devices (iPhone 4, iPad 1). Maybe someone here can help me out, I'd be ever so grateful.
I set up iTunes on my MBP yesterday and logged in to my account. I replaced the empty iTunes Media folder with my old one (which contains all my music, videos and applications) via an external hard drive.
First problem: it wouldn't import these files into my new library automatically. Just showed me an empty library I think I imported the entire iTunes Media folder manually yesterday via "Add to folder". The status right now (after some experimentation) is old iTunes Media folder copied, but nothing imported (that is, I have an empty library).
When I connected my iPhone and tried to synch, I first had to authorize the MacBook for the iPhone. So far, so good. However when I tried to synch iTunes warned me that if I synch, all data on the iPhone will be removed and replaced by the data from my new local library (which is, of couse a copy of my old library, but doesn't store application data like savegames).
I tried to do it via "transfer purchased items from iPhone", which took forever, but yielded the same result: a warning that all data on the iPhone would be erased.
So the question is: How do I connect my iPhone and iPad to iTunes on my new Mac without losing application data like settings and savegames? And why is this so complicated and intransparent? I should be able to just copy my media, say "authorize this Computer, then add iPhone to the registered devices" and then proceed like nothing ever changed.
I searched the net until three in the morning yesterday, but couldn't find anything that sounded safe enough to give it a try.
Thanks in advance and best Regards,
Nate
PS: I do have the backup-folders from my old PC on a USB stick - are those going to help?

I was fighting this battle the past few days myself; but actually it is REALLY easy now. See here:
http://www.macworld.com/article/146958/2010/03/moveitunes_windowsmac.html
Then, once iTunes was on the Mac, I did this:
1. On the Mac rename ...\iTunes\iTunes Library.itl as ...\iTunes\iTunes Library
2. On the Mac delete ...\iTunes\iTunes Library Genius.itdb (Apparently the PC & Mac versions are not compatible - iTunes will just rebuild it later)
3. Launch iTunes and immediately press & hold down the Option key until a dialog opens asking you to Choose a library. Navigate to the folder/drive you've copied from the PC and open ...\iTunes\iTunes Library.
(thanks to turingtest2 for the above steps)
That was it. Did it yesterday evening. All playlists, libraries, everything copied fine. No problems; no broken links. Perfect.

What is the proceedure for replacing a hard drive (after failure) for RAID 5 with IX4-300D?

I have the IX4-300D with 4 hard drives (identical Seagate drives) using RAID 5.
Someday a hard drive will fail and I and I have to replace it. I read through the users manual briefly and I didn't see any documentation on how to perform a hard drive replacement and not lose any data.
So here are my questions:
1) I know per the instructions that Lenovo prefers using identical hard drives. Let's say in 2 years, 1 hard drive fails. Most likely, the same model Seagate hard drive will not be available. So will using a replacement hard drive by the same manufacturer with similar specifications work?
2) Will the front panel (or the software) tell me which hard drive has failed?
3) What is the proceedure for replacing a hard drive after a failure occurs? I read that the IX4-300D is not hot-swappable. So do I just power the IX4-300D down, replace the hard drive, and turn it back on?
Solved!
Go to Solution.

Hi exceptionalht,
It is best to replace the hard drive with one that is the same manufacturer, rotational speed, and capacity, so it does not have to be exactly the same model.
The front panel should show which drive has failed. If not you can check the web interface to find out.
That is the basic procedure for replacing a hard drive. You can see a more detailed instructions here: Installing hard drives in an ix4-300d

I need confirmation, please help me! (about adding new hdd on my ix4-300d)

Hello,
I buy recently a Lenovo ix4-300d, I have installed one hdd seagate 2To (ST2000VN000).
I saved many documents on it..
Today I want to install 2 others hdd WD 1To (WD10EZEX).
After reboot a message tells me I need to erase all data on the news disks before I can use it, so I confirm, all seems ok.. After that a message appear on the left "2 disks unused".
Now (step 3 page74 on the .pdf guide) I need to check the box "add drives to storage system" and click confirm to activate the news disks, so I do, but I have this message:
"Vous devez supprimer les données existantes pour pouvoir modifier la configuration du disque.
Cochez cette case pour continuer."
(in english "You must erase existing data for change the disk configuration" or something like that)
I don't want to loose all the data on my first hdd already in use.. ..and the 2 others news disks are empty.
So, there is my question:
if I check the box and click continue what "existing data" will be erase??
existing data on all hdd?? Or just on the new one??
nb: Sorry for "my english" but there is no french section in the forum, and the assistance don't answer me by email, and on the phone there is an answerphone tells me "for help if you don't have the error number code, you must go on the forum, bye.." .. .. I hope my question is understandable.
Thanks

Hello tictictac
Sorry that you experienced data loss, however it was preventable if a backup had been made as recommended.
From the screen shot you sent it looks like the drives were already added to the existing array after the first drive overwrite request. With the array being made up of mixed disk models and none of the disks showing any green stipes indicating overwrite selection, I can not say for certain what caused all the disks to be wiped. I suspect that is was taken as a RAID change and all disks were wiped from there.
For future reference please check the device support page to see the guides, FAQ's, and download the full user manual( in French here ) and check with LenovoEMC support in your region.

Ix4-300d network interface going off-line

I just got a new ix4-300d to use as an iSCSI target in a relatively low-performance requirement file server.
I have used ix4-200d and ix4-300d in the past for iSCSI targets in disk-based backup scenarios wihtout issues.
I am having problems with this one, though. I am attempting to copy data to this new unit (with a VHD mounted from the iSCSI connection to the system), and while data seems to copy OK, at some point the network interface quits working somehow.
When this occurs, the unit still thinks that the interface is configured, and everything seems OK, I just cannot connect. Obviously, this causes my iSCSI initiators to die, and the VM hosted crashes hard. At that point, I have to restart the storage unit, and then reconnect my initiators, and then bring everything back online.
I've updated the firmware to the latest, but it wasn't that far out of date. I've found an article titled "Network storage device is not assigned an IP address" in the knowledgebase that points ot a problem with the software in the 4.0.2 series, and I was at 4.0.6, and am now current in 4.0.8. I am testing the process again, but wanted to check with the community to see if anyone has experienced anything similar and/or could offer some idea of why this interface quits working.
For what it's worth, the other units I have worked with were all in the 3.x series of software.
Thanks for any help/information anyone can provide.
Solved!
Go to Solution.

Hi chloeroxymax,
Do you have discovery enabled?
If not, check the box for "Enable discovery with iSNS" under the iSCSI settings and select "Use local iSNS server".
Then, on your iSCSI Initiator, go to the Discovery tab. Click "Add Server" under iSNS servers and enter the IP address of the NAS.
The device should show up under the Targets tab (you may have to click the refresh button)
On your other NAS devices, go to the iSCSI settings page and select "Enable discovery with iSNS" but select "Use external iSNS server" and type in the IP address of the ix4-300d NAS.
This may help things run smoothly. If the device is still disconnecting, I would recommend contacting technical support since this is a new device and you are covered by the warranty for support.

Time Machine couldn't complete the backup to "Time Capsule. The backup disk image /Volumes/Data/MacBook Pro.sparsebundle could not be created (error 60)"

We are Mountain Lion using Time Machine to backup to Time Capsule. When the backup tries to run, an error appears after a couple of minutes saying "The disk you inserted was not readable by this computer." Then an error shows up saying "Time Machine couldn't complete the backup to "Time Capsule.The backup disk image /Volumes/Data/MacBook Pro.sparsebundle could not be created (error 60)"
I low level reformatted the Time Capsule and that didn't fix it. I then tried using Time Machine on another computer to back up to that same Time Capsule and it worked- so I'm doubting it's the Time Capsule.
I've noticed that when Time Machine runs, that a folder called Data at /Volumes/ appears while Time Machine is trying to back up. I think it's making the sparsebundle to transfer to the Time Capsule.
However, after a couple of minutes- it comes back saying that the disk is unreadable.
I think it's something wrong with either creating the sparsebundle or opening the disk image that seems to be a part of the Time Machine backup process on the local drive.
I am able to create a disk image with Disk Utilitiy without any problem on that system. I've repaired the disk and disk permissions with Disk Utility and replaced the directory with Disk Warrior. I've trashed what preference files I could find and restarted. I've completely removed the backup destination from the computer and added it back again.
Help!
Thanks,
Neil

Yes, exactly. It makes one sparse bundle per Mac.
It's possible the TC's disk is too full for a new sparse bundle, or there may be some other problem.
Via the Finder, locate the existing sparse bundle (see the pink box in Time Machine - Frequently Asked Question #17 if you're not sure how to do that). See how large it is (plus how large anything else that may be there). If the total is very near the size of the TC, that may be the problem.
If not, a clue may be lurking in your logs. Use the widget in #A1 of Time Machine - Troubleshooting to display the backup messages from your logs. Locate the backup in question (probably the first one displayed), then copy and post all the messages here.
