Enabling a disk for Extended Copy Service operation

 To enable a disk for Extended Copy Service operation

1. Install the Hardware Assisted copy license.
2. Enable the Ecopy features in the array. This procedure is vendor-specific.
3. Install the vendor ASL that supports the Ecopy feature. contact VITA@veritas.com for vendor ASL information.

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
