Suspend Remote Mirror; Suspend Performance Read Cache - IBM System Storage DS3000 Programming Manual

Suspend Remote Mirror

This command suspends a Enhanced Remote Mirroring operation.
Syntax
suspend remoteMirror (primary [primarylogicalDriveName]
primaries [primarylogicalDriveName1 ... primarylogicalDriveNameN])
writeConsistency=(TRUE | FALSE)
Parameters
Parameter
primary or primaries
writeConsistency
Notes
If you set the writeConsistency parameter to TRUE, the logical drives must be in a write-consistency
group (or groups). This command suspends all write-consistency groups that contain the logical drives.
For example, if logical drives A, B, and C are in a write-consistency group and they have remote
counterparts A', B', and C', the command:
suspend
remoteMirror logicalDrive ["A"] writeConsistency=TRUE
suspends A-A', B-B', and C-C'. If you have a write-consistency group 1={A, B, C} and write-consistency
group 2={D, E, F}, the command:
suspend remoteMirror logicalDrives=["A", "D"] writeConsistency=TRUE
suspends both write-consistency groups.

Suspend Performance Read Cache

This command temporarily stops caching for all of the volumes that are using the Performance Read
Cache. While caching is stopped, host reads are serviced from the base volumes instead of from the
Performance Read Cache.
Syntax
suspend performanceReadCache [performanceReadCacheName]
Description
The name of the logical drive for which you want to
suspend operation. Enclose the logical drive name in
square brackets ([ ]). If the logical drive name has
special characters, you must also enclose the logical
drive name in double quotation marks (" ").
This parameter defines whether the logical drives
identified in this command are in a write-consistency
group or are separate. For the logical drives in the same
write-consistency group, set this parameter to TRUE. For
the logical drives that are separate, set this parameter to
FALSE.
