Goal

How to manually re-scan for SAN Fibre Channel (FC) Disk (LUN) and Tape Storage devices.

Note: Solaris needs to properly see a LUN before a particular application software, such as, multipathing or back up software, can use the LUN.

Same commands can also be used to determine what LUNs are currently being seen by Solaris.

To check for a specific LUN the FC storage target port World-Wide Number (WWN) where the LUN is presented from will need to be provide by customer.

If the FC storage target port World-Wide Number (WWN) is not seen by commands then that has to be addressed first. The FC Storage and/or FC Switch administrators will need to verify FC storage target port World-Wide Number (WWN) has been properly configured to be seen by the specific FC HBA port WWN.

Once the FC storage target port World-Wide Number (WWN) is seen by commands then the LUN number (in decimal not hex) will need to be provided by customer in order to check whether it is currently seen by commands.

If other LUNs are seen from same FC storage target port World-Wide Number (WWN) but not the LUN being checked for then issue is outside the server on the FC Storage.
