[ovirt-users] Storage Domain ISCSI Inactive

[aditya hilman]

Hi Aharon,

Yes, I remove the lun from the storage.
The problem already solved, but a little bit confuse about the iscsi
session on rhev-m.
I create new lun and rhev-m recognize the new LUN properly
But when I delete the previous lun, the rhev-m still showing the lun but
the lun marked as unavailable lun.
For solving the "cache" issue on the rhev-m, running "iscsiadm -m session
-u" and relogin with "iscsiadm -m node -l".
The issue is when I relogin the iscsi target on rhev-host, the running VM
would be paused.

There any other method to "clear cache" the lun on rhev-m ?
