Hello, I need some help since I cannot see my datastore anymore.
I have a server Dell Poweredge with PERC H310 controller. This server had three SATA 4Tb configured as RAID5. This virtual disk was being seen from ESXi as a datastore named "DATI".
A couple of weeks ago one of these disk being degraded. I had some trouble finding SATA replacement, so I decide to move to SAS disks.
I bought 3 SAS Dell disk (4Tb). These are the operation I did in order to migrate the VM from the old datastore to a new datastore.
-put the defective SATA disk offline
-remove all SATA disks
-insert the three new SAS disks
-restart the server
-create a new virtual disk with SATA RAID SAS named DATA1
-put one of the SAS disks offline and remove it (so two bay are available)
-insert the two SATA disks still OK, accepted as foreign
-now I can see two virtual disks (SATA and SAS) both 7Tb
-start ESXi and create a new datastore with the new SAS virtual disk
-copy 5 VM machines to the new datastore (lot of time spent here...)
-unregister VM from old datastore DATI and register these VM on datastore DATA1
-start these 5 VM: all VM (Windows server, some 2008 one 2012 with Veeam Backup&Replication Suite) started an successfully working
Now I was ready to complete the migration from SATA to SAS, so I decided to remove these old SATA drives. So I:
- shutdown ESXi server
- removed the two old SATA disk and mounted the third SAS disk (so this RAID5 can be completed)
- power on server, enter in PERC controller and put this third disk online
- restarted the server and started ESXi
Now the trouble: datastore DATA1 disappeared in web console. I can see the disk as storage:
In the output of the command esxcli storage filesystem list I can see the disk:
unknown.vmhba1-unknown.2:0-naa.6b083fe0e9e63c0023b10b410d2f4655

When I enter in the /vmfs/volume directory I see something but I'm not sure what is this link:
I don't want to do it all over again. Please could you tell me how can I have this datastore available in the ESXi ?
Thanks a lot.
