CLPR list
The figure below shows the CLPR list, which is located in the upper-right corner of the Cache
Residency window. Use the CLPR list to select the CLPR containing the desired CUs and LDEVs.
The cache information for the selected CLPR and the CUs and volumes belonging to the selected
CLPR will appear in the Cache Residency window.
If you administer more than one CLPR, use the CLPR list to select a CLPR by name and number. If
you administer only one CLPR, the CLPR list displays only the CLPR that you have access to and
does not allow you to select other CLPRs.
For more information about cache logical partitions, see the HP StorageWorks XP24000/XP20000
Disk/Cache Partition User Guide.
Pre-staging checkbox
The figure below shows the pre-staging checkbox that is located in the upper-left corner of the
Cache Residency window. The pre-staging checkbox is used to enable and disable the pre-staging
function for Cache Residency.
•
The Pre-staging check box allows you to enable and disable the pre-staging function:
◦ If you select the Pre-staging check box and click Apply, a Yes/No confirmation displays.
To perform a Cache Residency operation followed by a pre-staging operation, click Yes.
To perform only the Cache Residency operation, click No.
◦ If you clear the Pre-staging check box and click Apply, only a Cache Residency operation
is performed. If you select this check box later and click Apply, a Yes/No confirmation
displays. A Yes click performs only the pre-staging operation.
The Pre-staging check box is selected by default. The Pre-staging check box is unavailable when
the Pre-staging Mode is set to No for each cache extent.
The Pre-staging check box can be selected only when you are logged in to Remote Web Console
as a storage administrator. If you are logged in as a storage partition administrator, it cannot be
selected.
CU:LDEV tree
The figure below shows the CU:LDEV tree, located in the upper left area of the Cache Residency
window. The CU:LDEV tree lists the LDEVs that are available for Cache Residency operations. The
LDEVs are identified by LDKC number, CU number, and LDEV number (such as, “LDEV 00:01:48”
is LDEV 48 in CU 01 in LDKC 00). An LDEV number ending with (“#” mark indicates that the LDEV
is an external volume (e.g., 00:00:01#).
Only the volumes belonging to the selected CLPR are shown. Volumes that are reserved for Auto
LUN and Compatible PAV alias volumes are not displayed, because those volumes are not available
for Cache Residency operations.
