Managing SAN Devices and Multipathing in Oracle^® Solaris 11.3

How to Remove Fibre Channel Device

Before You Begin

You must stop using the logical unit device which you want to remove. For example, you can either unmount the file system or export the ZFS pool.

1. Become an administrator.

   For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.3.

2. Verify that the LUNs are reported as unusable in your system by using the following command.

   The removed LUNs are marked as unusable.

   # cfgadm -al -o show_SCSI_LUN
