Description
Selects the mode for the data to be added to Cache Residency cache:
Bind: Sets the bind mode. Bind mode is not available to external volumes
whose cache mode is set to Disable (which is the mode that disables the use
of the cache when there is an I/O request from the host).
Prio:Sets priority mode.
Once you have requested a Cache Residency operation, the mode options are
unavailable. To change the mode for a requested operation, cancel the requested
operation and request the operation again with the desired mode selected.
Enables or disables the prestaging mode for the requested operation:
Yes: Enables prestaging mode.
No: Disables prestaging mode.
The Prestaging Mode options are unavailable when the Prestaging check box
is unchecked.
Once you have requested a Cache Residency operation, the Prestaging Mode
options become unavailable. To change the mode for a requested operation,
cancel the requested operation and request the operation again with the desired
mode selected.
Enter the starting and ending addresses for the data to be placed in cache,
specified in LBAs for open-systems LDEVs, and in CC HH numbers for
mainframe LDEVs.
For OPEN-V LUs, logical areas are defined in units of 512 blocks. If you enter
0 or 1 as the starting LBA and a value less than 511 as the ending LBA, Cache
Residency automatically changes the ending LBA value to 511.

address (From and To) fields are cleared.

When checked, the operation can be applied to multiple LDEVs. When
unchecked, the operation is applied to only one LDEV.
This feature does not allow you to select and cancel an individual Cache
Residency data area specified for an LDEV. You must perform a Release
operation to cancel an individual data area.
