Enabling Extended Copy Service for Hitachi arrays
To implement extended copy for the Hitachi 9900 and 9900V arrays, use the following
command to create the two files, /etc/vx/user_pwwn_file and
/etc/vx/user_luid_file, that contain identification information for the disks.
# /etc/vx/diag.d/vxwwnluid
This command must be executed as root.
The user_pwwn_file file contains the disk access name and the port world-wide-
name (pwwn) for each disk in the array. For the Hitachi arrays, both the source and the
destination devices must have entries in the this file. The information for each disk in the
array is defined on a single line. The disk access name and PWWN are separated by a
single tab character.
The following are sample entries from the user_pwwn_file file:
c1t22d0 50060e800404040b
c1t23d0 50060e800404040b
c1t24d0 50060e800404040b
The user_luid_file file contains the disk access names and their corresponding
LUN numbers in the array. The information for each disk in the array is defined on a
single line. The disk access name and the LUN are separated by a single tab character.
The following are sample entries from the user_luid_file file:
c1t22d0 1
c1t23d0 2
c1t24d0 1
Removing disks
Note: You must disable a disk group as described in “Disabling a disk group” on page 199
before you can remove the last disk in that group. Alternatively, you can destroy the disk
group as described in “Destroying a disk group” on page 200.
You can remove a disk from a system and move it to another system if the disk is failing or
has failed.
