How to Determine Your Cache Module Type

To determine your cache module type (version type and number of megabytes),

enter the SHOW THIS_CONTROLLER or SHOW OTHER_CONTROLLER

command at the CLI> prompt as appropriate.

Note

The original HSJ40 array controllers shipped with Version 1 read cache

modules. The HSJ30, HSD30, and HSZ array controllers all ship with

Version 2 read cache modules.

You must have HS operating ﬁrmware Version 1.4 or greater to operate

with a Version 2 read cache module. The Version 2 read cache modules do

not operate with ﬁrmware prior to Version 1.4. However, Version 1 read

cache modules operate with all versions of HS operating ﬁrmware.
