1 In the AMW, select Storage Array Change Cache Settings.

The 

Change Cache Settings window is displayed.

2 Select or enter the percentage of unwritten data in the cache to trigger a 

cache flush in

Stop flushing.

4 Select the appropriate Cache block size.

A smaller cache size is a good choice for file-system use or database-

application use. A larger cache size is a good choice for applications that 

generate sequential I/O, such as multimedia.

5 In the Enter Password dialog, type the current password for the storage 

array, and click 

OK.

When an MD1200 series expansion enclosure is connected to an MD3200 

series storage array for the first time, an enclosure ID number is assigned and 

maintained by the expansion enclosure. This enclosure ID number is also 

shown in the MDSM.
To change the enclosure ID numbers: 

1 In the AMW, select the storage array, and select Storage Array 

Change Enclosure ID.

2 Select a new enclosure ID number from the Change Enclosure ID list. 

The enclosure ID must be between 0 and 99 (inclusive).

3 To save the changed enclosure ID, click Change.

You can change the order of the RAID controller modules and the expansion 

enclosures in the Physical pane to match the hardware configuration in your 

storage array. The Physical pane that initially appears is a default view that 

may not match your storage array. The enclosure order change remains in 

effect until it is modified again.
