ISCI LUN 1 Dissappears in storage

[MosheFriedman]

HELP !!!!!!!!!!!!!! I have three Iscsi Volumns (see Below info from Storage Adapters) which had Data (off a THECUS NAS SERVER). However LUN 1 got corrupted, and now shows 0.00 B Capacity (see below) and cannot be accesed in Storage!. Is there any way to reclaim the LUN!

Thanx

You have to check first on storage site, whether iscsi target for Lun 1 is up/enable or not. Probably your Lun 1 still there, but inexplicably disabled for unknown reason.

I believe, THECUS using ietd iSCSI like Synology NAS. If that the case and you able to ssh to your THECUS, run both commands as shown below to check all targets available for connection & current iscsi session.

$cat /proc/net/iet/volume

tid:7 name:iqn.2000-01.com.esx1.disk1

lun:0 state:0 iotype:blockio iomode:wt path:/dev/md3

$cat /proc/net/iet/session

Thanx, but there is NO SSH access to the Thecus Server, However I went ahead and changes the ISCSI identifier on the THECUS box (I changed the date), and deleted the static path from VSphere, rescanned HBA & lo & Behold the DATASTORE reappeared with all its data INTACT!

Thanks for the try
