Extended Copy Service Support for Hitachi 9900 and 9900V Arrays
To implement extended copy for the Hitachi 9900 and 9900V arrays, you must create the two
files, user_pwwn_file and user_luid_file, that identify the Hitachi disk identification
information. To create these files, run the vxwwnluid utility that is located in
/etc/vx/diag.d. There are no parameters for the vxwwnluid utility, and the command must
be executed as root.
• /etc/vx/user_pwwn_file
This 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 /etc/vx/user_pwwn_file file:
sde 50060e800404040b
sdf 50060e800404040b
sdg 50060e800404040b
• /etc/vx/user_luid_file
This 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 /etc/vx/user_luid_file file:
sde 1 sdf 2 sdg 1
Administering Array Support Library Packages
Base-VXVM provides Dynamic MultiPathing (DMP) support for new disk arrays in the form
of Array Support Library (ASL) software packages. You can obtain ASL packages for new
arrays from:
• The VxVM release in the veritas_enabled directory.
• The Storage Array Vendor’ s support site.
