STORAGE - NetApp - Unable to assign serial number to LUN

         STORAGE - NetApp - Unable to assign serial number to LUN

While attaching the LUN to an igroup which has the host iscsi initiator target set sometimes you might run into a problem wherein the LUN doesnt get attached to the igroup hence not allocating the block based space to the host.

This can be rectified by setting up the counter on your NetApp system --

On your Filer head

Run the following command -

# priv set diag

# lun sn-counter show

This will shoe the current value of the counter.

This would display the countyer set for generating the serial numbers.

#lun sn-counter set -t

This will reset the counter to default.

Once done try to allocate the LUN once again and you should be good to go.

Thank you..
