1. Record the name of the array with failed or new hardware (current destination) and the name
of the current source array in a log such as the one shown in Table 6 (page 112). For example,
the array with new hardware is named HSV01 and the current source array is named HSV02.
Refer to this table during the procedure as needed.
2. If running controller software versions prior to 6.1xx on the current source array, resume all
DR groups.
3. Delete all DR groups that have had a relationship with the failed hardware.
4. Install the replacement array and configure as necessary (for example, disk groups)
5. Re-establish communication between the source and new destination arrays. Add the new
array to the SAN, enable the ISLs, or place the arrays into the same zone.
6. Perform one of the following:
• If the replaced array configuration was captured with HP Storage System Scripting Utility
(called the utility), execute the script ConfigName_step1A on the new hardware, and
then proceed to Step 11. See the HP Storage System Scripting Utility Reference for
instructions. ConfigName is a user-assigned name given to the utility script at the time
of creation. See “Backing up replication configuration” (page 126).
• If you are not using a utility script for recovery, initialize the repaired or replaced array
using the information you recorded in Table 6 (page 112). See the HP P6000 Command
View User Guide for initialization instructions.
NOTE: To preserve existing zoning, assign the new hardware the WWNs of the failed
hardware.
7. Add the disk groups on the new hardware.
8. Add the hosts for the system with new hardware.
9. Create the non-DR group virtual disks.
10. Present all non-DR group virtual disks to their hosts.
11. Perform one of the following:
• If the source array configuration was captured with the utility, execute
ConfigName_step2 on the source array. ConfigName is a user-assigned name given
to the utility script at the time of creation. DR groups are re-created with the utility if they
were performing as the source when the configuration was captured. This step may take
some time to complete.
This action includes the following assumptions:
◦ The new array has the same type of hardware as the array that failed.
◦ All host WWNs are still the same.
