How to re add the disk on the LUN

[shinrei82]

Hi guys,

 

I have my xpenology DSM 5.2-5592 Update 4 running on ESXI 5.x with 3 disks in a LUN (RDM). After some manual reboot (xpenology and esxi), the xpenology does not want to power on.

 

The log en ESXi said:

Cannot open the disk '/vmfs/volumes/.../4To_WD40EFRX2D68WT0N0.vmdk' or one of the snapshot disks it depends on. 19 (No such device)

 

This disk still exist "...T0N0.vmdk":

 

/vmfs/volumes/54b2b2dd-e3dc7654-xxyy-fcaa14227183/RDM # ls -al

total 1032

When i check on the Xpenology configuration, the disk 2 seems NOT to be part of the LUN. The disk 3 and 4 are in a LUN. I have deleted it and try to re add but esxi does not recognize the file "4To_WD40EFRX2D68WT0N0.vmdk".

 

Anyway, the disk is deleted and i could boot up in a degraded volume

 

I will check this disk on the bios tomorrow. But what do you think?
