Troubleshooting LUNs

To ensure that the LUNs are available to all controllers:

NOTE: A common issue can be a preceding or trailing space. To view the IQNs of the controllers, via the NAS
command line enter the command system maintenance luns configuration iscsi-view.
2. Ensure all hosts are part of the host group in the MDSM.
3. Ensure all virtual disks are mapped to the host group in the MDSM.
4. Verify from the NAS command line that the correct IP was entered as the discovery IP for the MD storage array.
To view the iSCSI discovery IP, enter system maintenance luns configuration iscsi-view.
To change the iSCSI Discovery IP, type system maintenance luns configuration iscsi-set -
iSCSIDiscoveryIPs <iSCSI Discovery IP> None None where, <iSCSI Discovery IP> is
the iSCSI port IP of the MD storage array.
