Datastore not mounting after RAID rebuild from failed drive

[taspence]

VMWare ESXi 5.5.0 - I have an HP Server with a RAID 5 configuration that after replacing a (1) drive and re initializing the RAID, my datastore is now not mounting. I have two missing VM's. In the storage configuration I should have 2 datastores. Under datastores only one is showing. Under devices I I show two devices. naa.600508b1001c698c8f8380587e5cc212 is what I am after. If I rescan, it does not mount. If I go to add storage, choose LUN, and regardless if I choose VMFS-5 or VMFS-3 I get prompted with "this configuration will delete the current disk layout. All file systems and data will be permanently lost."

Running partedUtil getptbl /vmfs/devices/disks/naa.600508b1001c698c8f8380587e5cc212

I get

gpt

145875 255 63 2343487580

1 2048 2343481874 AA31E02A400F11DB9590000C2911D1B8 vmfs 0

Running partedUtil getUsableSectors /vmfs/devices/disks/naa.600508b1001c698c8f8380587e5cc212

I get

34 2343487546

Running esxcli storage vmfs snapshot list bring be back to the command prompt so I'm guessing its not viewing it as a snapshot

I have a hard time believing that the raid wiped my data with the rebiuld of just one drive in a raid 5.

Any guidance would be appreciated. Thank you.

During rescan, are you seeing any errors for the LUN <naa.600508b1001c698c8f8380587e5cc212> in vmkernel.log? Can you run the below command and share the output that is starting with the offset <00200000> until the start of next offset?

hexdump -C /vmfs/devices/disks/naa.600508b1001c698c8f8380587e5cc212 | less

Cheers,

Can you please provide some more details.

• What type/model of RAID controller do you use?
• How did you replace the disk (Hot-Swap, or with the host powered off)?
• In case of Hot-Swap, how long did you wait after removing the failed disk, and inserting the new one?
• What exactly do you mean with "re initializing the RAID"?

Anyway, since the partition still shows up, I'd suggest you try to contact community user continuum​ prior to trying anything that may make things worse.

If you create a VMFS header dump and send it my way I can probably assist you.

Thanks for you attention. Sorry for my english.

That does not look good.
Did you try to create a dump of the VMFS-partition ?
If this datastore has valuable VMs I would suggest that you call me via skype.
