You shouldn't try trust command without checking logs by some MSA specialist. If you have contract with HPE then log a support case with HPE

How vd01 went to offline state?

You can also check system events and find out if any drives having any hardware errors. If all drives health ok then you can run the below command,

#trust enable

#trust vdisk vd01

# show vdisks

You can also share the MSA logs with me in private chat and I can check the same.

Keep in mind that you shouldn't execute trust command multiple times on a vdisk otherwise drive metadata will get corrupted and no one can recover data from the vdisk.

 

Hope this helps!

Re: SAN (P2000 G3 iSCSI) Vdisk Raid5 offline

Bundle Version: TS230P008

It looks like this MSA running with very old or expired or inactive firmware so there is no gurantee that Vdisk will come up or not.

Three drives at location 1.2, 1.11 and 1.12 shows big number of recovered errors which looks bad as well.

Anyway you can try the below commands,

#trust enable

#trust vdisk vd01

# show vdisks

Once vdisk came up. Take data backup. Then plan for downtime and stop Host IO or disconnect Host from MSA. Then upgrade MSA controllers to latest version TS252P005

Upgrade Path -> TS230 -> TS250 -> TS252

www.hpe.com/storage/MSAFirmware 

 

Then you may have to plan and replace faulty drives one by one.

 

Hope this helps!

I forgot to mention that you need to physically re-seat drive at location 1.10 then only you can try the commands that I have suggested because 1.10 now missing and that is the last drive for which vdisk went to offline state

If even after re-seat 1.10 not coming up then there is no way to recover this vdisk

Vdisk was made with 11 drives in RAID5. Right now only 9 drives present. As you know RAID5 can't sustain more than one drive failure. Here two drive missing which are 1.6 and 1.10 so vdisk in offline state as this is RAID failed. We don't need 1.6 anymore but If we re-seat 1.10 as that is having latest data so We can try recovering this vdisk as that time we will have 10 drives in vdisk which is meeting RAID5 criteria which will help to recover the vdisk but again it depends upon in what condition 1.10 is. If controllers not able to read data from 1.10 then data recovery not possible.

1.6 failed on 30th Dec 2017 but no one replaced it.

 

Hope this helps!

it s not working :

 

# trust enable
Success: Command completed successfully.

# trust vdisk vd01
Error: Command failed.

Re: SAN (P2000 G3 iSCSI) Vdisk Raid5 offline

Is 1.10 now detected by controller?

As told you before there are multiple drive having issue which will not allow to recover the vdisk

You can log support case with HPE if they can recover

 

Hope this helps!
