•
Volume: Port - GID (host group number) - LUN of the selected volume.
If the pound or gate symbol (#) is added to the end of the device ID (00:00:3C #, for example),
the LDEV is an external volume. For details on external volumes, see the HP XP24000/XP20000
External Storage Software User's Guide.
If an X mark is added to the end of the device ID (00:00:3C X, for example), the LDEV that
the number indicates is a Thin Provisioning virtual volume. For details on virtual volumes, see
the HP XP24000/XP20000 Thin Provisioning Software User's Guide.
•
P-VOL Fence Level: Select the fence level for the new pair(s). The fence level determines the
conditions under which the MCU will reject write operations to the P-VOL. Never is automatically
set for an asynchronous pair. See
for further information on this
option.
◦
Never: The P-VOL will never be fenced.
◦
Data: The P-VOL will be fenced when the MCU cannot successfully execute an update
copy operation for any reason.
◦
Status: The P-VOL will be fenced only if the MCU is not able to change the S-VOL status
to suspended when an update copy operation fails.
•
Asynchronous Parameters (async only):
Error Level: Error level for the new pair(s): Group or LU.
•
The Cancel button cancels the settings you have made and closes the Change Pair Option
dialog box. The Set button sets the parameters and closes the Change Pair Option dialog box.
To set the parameters on multiple volumes at once without changing individual parameters per
volume, make the box for parameters that you do not want to change blank. Only the parameters
that you input will be changed.
