Preparing to transition SAN boot LUNs on HP-UX hosts with FC configurations
Before you transition a SAN boot LUN on an HP-UX host with an FC configuration, you must record the name of the 7-Mode LUN on which HP-UX is installed, the SCSI device name for that LUN, the Agile naming convention, and the WWID.
-
From the console of the 7-Mode controller, display your 7-Mode LUNs to identify the LUN name on which the “HPUX11v3 March 2014” operating system is installed:
lun show
-
Obtain the SCSI device name for the LUN:
sanlun lun show -p
In this example, the transition LUN is bootlun_94. The SCSI devices for this LUN are
/dev/dsk/c14t0d0
,/dev/dsk/c27t0d0
,/dev/dsk/c40t0d0
, and/dev/dsk/c31t0d0
.ONTAP Path: f8040-211-183:/vol/vol_183/bootlun_94 LUN: 0 LUN Size: 100g Host Device: /dev/rdisk/disk6 Mode: 7 Multipath Provider: None host vserver /dev/dsk path path filename host vserver state type or hardware path adapter LIF ----- ------- ---------------- ------- ------- up secondary /dev/dsk/c14t0d0 fcd0 fc4 up primary /dev/dsk/c27t0d0 fcd0 fc2 up primary /dev/dsk/c40t0d0 fcd1 fc1 up secondary /dev/dsk/c31t0d0 fcd1 fc3
-
Identify the WWID for the LUN on the host:
scsimgr get_info -D SCSI_device_name |grep WWID
In the following example, the LUN WWID for device
/dev/rdisk/disk6
is 0x600a09804d537739422445386b75556:bash-2.05# scsimgr get_info -D /dev/rdisk/disk6 | grep WWID World Wide Identifier (WWID) = 0x600a09804d537739422445386b755564 bash-2.05#
