PV 124t with BackupExec - TAflag[12] Unsupported Format

August 2, 2013, 3:45 pm

Hello all,

I setup the PV 124t with no problem, loaded it with tapes, and have been fighting with it to accept the tapes I am giving it are compatible, they are LTO 3 tapes, they work in other tape drives I have installed, so the tapes are in working order.

Anytime I try to do anything with them I get them TAflag[12] Unsupported Format  error on the PV itself, Symantec reports its translation of the error as "incompatible storage media detected in robotic library" so the PV is certain these tapes are unsupported.

I do not have this drive on the network, do I need to get it online so I can gain access to the web interface or is there another way to troubleshoot the drive?

Thanks.

Powervault MD3000 stuck with solid amber "reset state"

Hello,

My MD3000 array seems to be stuck in some sort of a (limbo?) reset state as per Dell manuals.

The only useful bit of information I can find says "Steady amber: Power is on and enclosure is in reset state.".... all other status lights are green (both controllers, battery, power.. etc.!)

Please could anyone suggest or confirm what this "reset state" is? Also, how does one get out of this solid amber reset state.

Best,

MD

I have a virutal server guest that is only getting 8MB/sec when I copy to its Data drive. The data drive is a VHD held on my MD3220i access via iSCSI.

 

If the hosts access the iSCSI I get approx 50MB/sec.

 

I haven't enabled jumbo frames as yet.

MD3200i Raid Controller Host Port configuration failing

I'm trying to change the IP address of Raid controller module 0, port 0.  Every time I try I get "Error 1007 - Could not communicate with the Raid controller module in slot 0 to complete this request.

I was able to change the IP address of the modules management port.  I am also able to change the IP address of module 1.  Further, I have swapped the two modules and get the same error.

Network cable is plugged in, port shows "connected".  Switch shows connection.  Baffled.

Anybody?

MD3000i appears to be only using 1 controller

We have been having some issues lately with disk performance in our VMware cluster. Our setup is as follows:

  • 3 Dell R610's running ESXi 5.1
  • 2 Juniper gigabit switches with 3 VLANs (1 for management, 2 for iSCSI)
  • 1 dual controller Dell MD3000i
After troubleshooting for a while, I found I could use SMcli to monitor the performance of the SAN. Upon doing so, the results were somewhat surprising as it looks like one of our controllers seems to be completely inactive. I have taken a screenshot of the results: (Ignore the name of the storage array. It was previously used in a XenServer setup)
My question is, how do I get it to where both controllers are acting as a pair for best performance. I would think there should be some way to have the VMware hosts take the quickest path to either controller to get to the disk, is there not?
Any help would be greatly appreciated as this has stumped me for quite some time and searching the internet hasn't gotten me very far.

MD3000i firmware issue.

Hi, I've been working with an md3000i and I've been running into an odd issue when trying to update to the newest firmware revision.  Everything seems to function perfectly on the controllers, everything is marked as good and get a blue led after the initial startup.  Now the issue is when looking at the firmware versions the controllers list as having 26.50.00.00.  I've looked around online and I've found no reference to this firmware version anywhere.  Now when attempting to upgrade using the cross generation upgrade utility the firmware file doesn't show up when selecting compatible firmware files and when going to all files and selecting the firmware file that way says it's not compatible and gives no more options.  As I said it appears to be functioning perfectly fine aside from this off the wall firmware version and the inability to upgrade.

Thanks in advance for any help as most of my online research hasn't found anything all that relevant to what I'm seeing.

PE-T610 with RD1000 Slow Performance

Hello,

The performance on our RD1000 has degraded significantly. We use the internal RD1000 on our SBS 2011 server to backup using Backup Exec 2010 R3. Assuming the performance issue might be caused by Backup Exec I proceeded to test by just copying files across using Explorer and found that I was getting about avg. 8 MBps. 

After some searches I found some documentation that gave instructions to re-install the RD1000 driver/software. I did this and rebooted the server to no avail.

ATA Channel 1 states Ultra DMA Mode 4.

Write Caching is enabled on the drive.

Compression is enabled on the drive.

Has anyone experienced this issue and found a solution? 

Thanks!

Rreceived RAS tickets T019 and T020, when looking inside the library, I could see that the -1 drive lable was peeling off. Suspect this is the cause of the calibrate errors.

What glue type should I use to re-stick the label back onto the tape drive.

MD3200i SODReboot lockdownmd

Hello,

I have a problem exactly as posted in this thread: http://en.community.dell.com/support-forums/storage/f/1216/p/19499337/20333114.aspx (Controller entering SODReboot lockdown state..) From the thread I understood that I need to run command lemClearLockdown from serial shell. But as the author of the topic I cannot log into the shell: after pressing Ctrl+Break in HyperTerminal and entering S nothing happens (no password prompt, cursor just moves to the next line).

So, could anybody help me and explain, how can I login into the shell to clear the lockdown state?

Performance for MD1200 vs local disks on PE R510

Hello,
I have a PowerEdge Server R510 connected to PowerVault MD1200 with SAS Cable 6Gb/s with PERC H800 controller (cache 1Gb NV).

On PE R510 I have 12x HD SAS Near Line 7200 rpm (connected to PERC H700 integrated), RAID 10.
On PV MD1200 I have 12x HD SAS Near Line 7200 rpm (connected to R510 with sas cable 6Gb/s with PERC H800 with 1 Gb cache NV), RAID 10.

On PE R510 I have a ESXi 5.1 U1 (installed on USB pendrive).
 

There are differences in performance between the two storage?
It's better local storage of server r510 or "outside" storage of MD1200?
Or the performance is equal?

Tnx in advance
Manuel

Moving current RAID drives *into* MD1000

Good day,

I have a poweredge 2900 that finally has died.

We would like to try and maintain the internal RAID5 (8x750GB) but the system board/chassis is dead. 

On idea was to move the disks and the PERC adapter to an MD1000 that we have 8 slots available.

Any idea on if this would be feasible. I.E. physically move drives 1-8 to the MD1000 and move the PERC adapter into the host machine.

Looking at the logs, all was well with the drives and Perc prior to the crash.

Second option would be buy a used PE 2900 and move the drives & controller to that. But this would be as a last resort

Thanks for any insight.

Dell PV TL2000 SNMP Community Strings and User Passwords

August 12, 2013, 1:44 pm

Has anyone else tried applying a SNMP Community String or User Password to their Dell PV TL2000 via the web management interface only to find out that the firmware (even the most current version which is C.00 / 3.20e) does not understand/accept any special characters in these two fields?

Was working on configuring the SNMP settings today on our tape library which we have had for 8 months now.  When I entered our typical READ ONLY community string name in the web interface, the system yelled at me.  The error was "Invalid community name! Only alphanumeric characters allowed.  Only 31 or less than 31 characters are allowed for the community name."  So I checked, and low and behold our community name was only 18 characters.  However, it has a special character in it; specifically a "?".  When I remove the special character, the system takes the community name just fine.

Same happens with passwords, however, the system doesn't even tell you that it did not accept the new password.  In fact, it doesn't tell you anything at all after clicking SUBMIT.  But if you use a password with special characters in it, it will now work; NO special characters and it works just fine.

I know this is only a tape library but come on Dell; any network security minded person will tell you that a combination of both upper and lower case, numbers and special characters should comprise your SNMP community strings as well as your passwords.  So why does the firmware NOT support it.

Finally, I opened a support case with Dell regarding the issue and was in essence told to blow off and that there was nothing that could be done.  OK....so what is the formal process to bring to the attention of Dell a Bug (which to me this is) in their system and that it should be corrected?

Hoping to hear back from a Dell Rep regarding this issue.  Thanks in advance for allowing me to vent.  Other than this issue though, this tape library with dual LTO6 tape drives in it is head over heels better than the current tape library the company was using when I got here last year; loving the TL 2000.

Sincerely,

Carey D.
