Howto remove a dead LUN from a strorage?

Hi all,

We have a dead marked lun on our ESXi 4 server

Runtime Name: vmhba35:C0:T3:L2

Device: naa.60003ff346387d08b2ed695b49734c4f

Device Display Name: MSFT iSCSI Disk (naa.60003ff346387d08b2ed695b49734c4f)

Adapter: vmhba35 Channel: 0 Target: 3 LUN: 2

Adapter Identifier: iqn.1998-01.com.vmware:esx4-170601be

Target Identifier: 00023d000001,iqn.1991-05.com.microsoft:rtg-nas01-vmware-target,t,1

Plugin: NMP

State: dead

Transport: iscsi

Any chance to get ride of it. I tried esxcfg-rescan -d vmhba35 but is still there.

Any idea?

Andreas

this dead lun left looks like vSphere limitation;

how about to run esxcli corestorage claiming unclaim --type device --device naa.60003ff346387d08b2ed695b49734c4f?

usually dead lun left due to dead iSCSI session, this dead session looks like unable to cleanup;

no more idea, but reboot should clean up

The problem has gone after waiting a while Smiley Happy The ESX has detected it and removed the dead device after waiting one phone call (40 minutes)

Thanks for your help.
