MSA Storage P2000 G3 FC - problem

Hi all


Recently we got some problems with one of our MSA2000

it looks like:

  The vdisk is not fault tolerant. Reconstruction cannot start because there is no spare disk available of the proper type and size.
  - Replace the failed disk.
  - Configure the new disk as a spare so the system can start reconstructing the vdisk.
  - To prevent this problem in the future, configure one or more additional disks as spare disks.

Success: Command completed successfully. (2014-11-14 09:36:56)

 

1)all LED indicators on the each one disk are "green"
2)what does it exactly mean "The vdisk is quarantined."
3)are these critical information above?
4)how to determine from command line which one exactly disk is FAULTY? (slot1 or slot2 or slot3... etc) - output of "show disks", "show disks encl" looks good
5)it is necessary to replace disk or something else we should do? (remember that all LED indicator are "green" and - output of "show disks", "show disks encl" looks good)
6)we haven't access to the both controllers of MSA 2000 through HTTP - only command line via telenet or SSH
7)I attached output of the commands: "show disks", "show disks encl", "show vdisks"
  from two different MSA 2000 - one from failure and one from good state
8)I searched events: [172]-none, [485]-only one:
  2014-11-10 21:08:36 [485] #B1999: P2000 G3 FC Array SN#00C0FF158487 Controller B WARNING A vdisk was quarantined to prevent writing invalid
  data that may exist on the controller that logged this event. (vdisk: , SN: 00c0ff15814d00003bb8de5100000000)  
  but it doesn't told me anything
  

If i can do anything more to clarify situation feel free to ask me
Thanks in advance for your help.


  Best regards

Re: MSA Storage P2000 G3 FC - problem

First problem in the first line:

 

Version: TS240P003

 

Currently we are at TS251P006-02.bin. There are so many fixes ...

 http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=4209076&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D%257CswItem%253DMTX_8253fde8ed454cdf9d477d29df%257CswEnvOID%253D4064%257CitemLocale%253D%257CswLang%253D%257Cmode%253D5%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vi...

 

 

next problem:

 

The vdisk is not fault tolerant. Reconstruction cannot start because there is no spare disk available 

 

"

quarantined

"

 

means more or less the LUN has failed, but maybe you can reactivate one of the "failed" disks somehow, so you have a single shot to activate the LUN again.

 

The SMU guide says:

A vdisk having a fault-tolerant RAID level becomes quarantinedif at least one of its disks is missing after
the storage system is powered up. Quarantine does not occur for NRAID or RAID-0 vdisks; if known-failed
disks are missing; or if disks are missing after failover or recovery.

 

Please read the chapter "Removing a vdisk from quarantine".

 

 QTOF means

Quarantined offline (QTOF): The vdisk is offline and quarantined because multiple disks are missing
and user data is incomplete.

 

Better discuss the issue with HP support, the system logs will provide more important information about what happened.


Hope this helps!
Regards
Torsten.
