This blog describes the problem and solution for ISCI Locks on OpenFiler with ESX 4.X
To resolve this issue one must perform an lunreset on the effected LUN. Before you can perform a lunreset you must find out the device path of the effected LUN.
On the ESX host you execute the following command:
# esxcfg-scsidevs –l
The output appears similar to:
Device Type: Direct-Access
Size: 512000 MB
Display Name: Openfiler1 Store 06
Console Device: /dev/sdj
Vendor: OPNFILER Model: VIRTUAL-DISK Revis: 0
SCSI Level: 4 Is Pseudo: false Status: on
Is RDM Capable: true Is Removable: false
Is Local: false
You will see a block like this for each LUN.
Look in the output for the line that starts with Devfs Path. With this information we can perform the lunreset.
On the ESX host execute the following command:
# vmkfstools –L lunreset /vmfs/devices/disks/ Devfs Path
# vmkfstools –L lunrest /vmfs/devices/diks/t10.F405E46494C45400A75707865567D2E4B463A7D285F61565
