Extend Cache slider: Adjust the slider to specify the capacity of cache memory you want to

allocate to each CLPR from the extended cache memory.
When you select one or more CLPRs in CLPR List in Subsystem, the scale is displayed and the slider

becomes available. The scale displays according to the capacity of the extended cache memory

and the number of CLPRs selected in CLPR List in Subsystem. For example, if you select 28 GB in the

Cache On-Demand in Subsystem's Extend box and select one CLPR in CLPR List in Subsystem, the

scale from 0 GB to 28 GB appears. If you select multiple CLPRs in CLPR List in Subsystem, the scale

displays with the greatest value that can divide equally (among the capacity of the extended cache

memory) by the number of CLPRs you have selected. For example, if you select 28 GB in the Cache

On-Demand in Subsystem's Extend box and select three CLPRs in CLPR List in Subsystem, the scale

from 0 GB to 9 GB is shown. Once you have decided the capacity of cache memory to be allocated,

and then re-select the CLPR in CLPR List in Subsystem to change the value of allocated capacity, the

scale is not from 0 GB but from the minus value of the decided value to the greatest value that can be

allocated. The slider knob is placed on 0 GB.

The Set button allows you to preserve the settings and close the Cache Detail pane.

The Cancel button allows you to cancel the settings and close the Cache Detail pane.

The following procedure provides steps for allocating extended cache mem­

ory to CLPRs. To extend cache memory using the On-Demand function, see

Extending Cache Memory Using On-Demand Storage Cache Function

.

1.

Select the desired incremental value (cache capacity) from the Extend drop-down list in the

Cache On-Demand in Subsystem section.

2.

When a confirmation pane appears, asking you to confirm that you agree to be charged for

access to the additional parity group, click OK to agree, or click Cancel to disagree

NOTE:

After you have set the allocating capacity of extended cache memory on the Cache Detail pane and

changed the value in the Extend box, another confirmation pane may appear if the newly set value

in the Extend box does not match the existing setting of the Cache Detail pane. If you want to allow

the existing setting of the Cache Detail pane to be initialized, click OK.

3.

Click Detail.
The Cache Detail pane appears (see

Figure 83

). The value selected in the Extend box is shown

in the Cache Pool's Extend column.

4.

Select one or more CLPRs for which you want to extend the cache memory in CLPR List in

Subsystem. The scale for the Extend Cache slider appears, and the knob becomes available.

5.

Drag the knob on the Extend Cache slider to the capacity you want to allocate to the selected

CLPRs.
The capacity of allocated cache memory is shown in the CLPR List in Subsystem's Extend column for

the selected CLPRs, according to the setting on the Extend Cache slider. The value in the Extend

column of Cache Pool decreases as much capacity as you have allocated to each CLPR. Cache Pool

and the selected rows in CLPR List in Subsystem change to blue bold italics.

6.

Click Set. The Cache Detail pane closes and returns you to the On-Demand pane.

Downloading Trace Files Using the FD Dump Tool

The XP Remote Web Console supports the FD Dump Tool function. The FD Dump Tool function enables

Storage administrators to download the XP Remote Web Console configuration information from the SVP

either onto a floppy disk or onto a hard disk drive. The downloaded information (trace files) can be

used by HP service personnel to diagnose problems related to XP Remote Web Console operations

for troubleshooting purposes.
