Unable to mount the existing LUN

[rvkrish25]

Hi All,

We are facing a critical problem, we have 2 EXSi 5.5 U3b which manage by V-Center

Unfortunately V-Center is one of the VM in 2 EXSi

Problem = We have 2*2 TB=4 TB of LUN mapped to 2 EXSi, Yesterday 3 VMs went inactive state rest of the VMs are active if we browse the LUN it show empty nothing available

I do the SSH of 2 EXSi and try to mount

/vmfs/volumes # cd xxxxxxxxxxxx

EXSi reply : -sh: cd: can't cd to xxxxxxxxxxx

I try to force mount # esxcfg-volume -m xxxxxxxx

Reply :  no matching volume xxxxxxxx found!

We are able to see the active FC adapters the links are up, we try to do "ADD STORAGE" in VSphere but it as for format so we canceled.

At last we decided to reboot the 2 EXSi so we have shutdown down all the running VMs and reboot once EXSi active but no luck we done "RESCAN" still in same problem state.

PLEASE ADVICE ME THE BEST SOLUTION TO HAVE MY EXISTING LUN WITHOUT ANY ISSUE.

Thanks

Venkat

Hi
At the moment the most important thing is to avoid panic-actions.
The range of problems that fit your description ranges from "only partitiontable missing" , "some files missing" upto "all gone"
Before you do anything provide a vmfs-header-dump - see
https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwi68oS1o8zNA...
Compress the result and provide a download.
With that data I can give you safe advice ...

Hi,

Thanks for your reply.

We found LVM header file corrupted vmware support team says we can not recover only option to restore backup
