30 Performing Compatible PAV Operations
NOTE: To cancel the alias included in another CU group, switch the CU group by step 1 and the follow
step 2 to step 5.

Considerations for Defining the XP1024/XP128/XP12000/XP10000 Devices to the
Host System
For XRC, do not intermix the 2105 or 2107 for XP12000/XP10000 controller emulation type with other
emulation types within the XP1024/XP128/XP12000/XP10000. If the
XP1024/XP128/XP12000/XP10000 has existing XRC volumes and you want to implement Compatible
PAV, complete the following steps to change to 2105 or 2107 emulation:
1. Stop all jobs and delete all XRC pairs.
2. Change the DKC emulation type of all CHA packages in the XP1024/XP128/XP12000/XP10000 to
I-2105 or I-2107 for XP12000/XP10000.
3. Restart jobs and re-establish XRC pairs.
NOTE: Compatible PAV operations require that one SSID be set for each set of 256 LDEVs.
Definition of XP1024/XP128/XP12000/XP10000 Base and Alias Devices
The unit address mapping for base and alias devices must be defined to the host operating system and
must match the address mapping defined at the Command View management station or XP Remote Web
Console. If the mappings do not match, serious failures can occur during data processing. The following
shows examples of mappings between base devices and alias devices.
(A) x00-x3F:Base (B) x00-x3F:Base (C) x00-x7F:Alias (D) x00-x3F:Alias
x40-xFF:Alias x40-x7F:Alias x80-xFF:Base x40-x7F:Base
x80-xBF:Base x80-xBF:Alias
xC0-xFF:Alias xC0-xFF:Base
