38 Preparing for External Storage XP operations
You must set the IO Suppression mode to Disable to use the mapped external LU for Continuous Access
XP operations. For a Continuous Access XP configuration example, see ”Using external LUs for
Continuous Access XP operations” on page 39.
• TrueCopy for z/OS
You must set the IO Suppression mode to Disable to use the mapped external LU for TrueCopy for z/OS
operations.
• Continuous Access XP Journal
You must set the IO Suppression mode to Disable to use the mapped external LU for Continuous Access
XP Journal operations. For a Continuous Access XP Journal configuration example, see ”Using external
LUs for Continuous Access XP Journal operations” on page 40.
• Universal Replicator for z/OS
You must set the IO Suppression mode to Disable to use the mapped external LU for Universal
Replicator for z/OS operation.
• Business Copy XP
You must set the IO Suppression mode to Disable to use the mapped external LU for Business Copy XP
operations. For a Business Copy XP configuration example, see ”Using external LUs for Business Copy
XP operations” on page 41.
• ShadowImage for z/OS
You must set the IO Suppression mode to Disable to use the mapped external LU for ShadowImage for
z/OS operations.
• Snapshot XP
You must set the IO Suppression mode to Disable to use the mapped external LU for Snapshot XP
operations. For a Snapshot XP configuration example, see ”Using external LUs for Snapshot XP
operations” on page 42.
• Compatible PAV for IBM z/OS
You must set the IO Suppression mode to Disable to use the mapped external LU for Compatible PAV for
IBM z/OS operations.
• Volume Security
You must set the IO Suppression mode to Disable to use the mapped external LU for Volume Security
operations.
• Volume Retention Manager
You must set the IO Suppression mode to Disable to use the mapped external LU for Volume Retention
Manager operations.
• LUN Security XP Extension
• You must set the IO Suppression mode to Disable to use the mapped external LU for LUN Security XP
Extension operations.
• If you previously mapped the external LU and set the VMA of LUN Security XP Extension in that
volume, the previous VMA setting is overwritten when you map the LU again. However, if LUN
Security XP Extension is not installed when you remap the LU, you cannot map the LU with the VMA
setting.
• SNMP
Information about the mapped external LU and external port is displayed.
• Configuration File Loader
• You can set the path definition for external LUs (add, delete, or change paths).
• You can set the command devices on external LUs (add or delete the setting).
• CHA mode, host group, and WWN settings for external ports are not supported. When an external
LU is mapped through that external port, the topology setting is not available.
NOTE: Some mainframe products might be marketed under different HP names and are not supported at
this time. Contact your HP account support representative for the latest support matrix.
