P440ar: Cache Status Permanently Disabled

[sinanpolat]

I am managing a ProLiant DL360 Gen9 server which has a P440ar RAID controller. I am using ssacli to manage the RAID storage.

I noticed the following error / problem:

=> ctrl slot=0 show status

Smart Array P440ar in Slot 0 (Embedded)
Controller Status: OK
Cache Status: Permanently Disabled
Battery/Capacitor Status: Recharging
=>

[sinan]$ sudo ssacli ctrl slot=0 show detail | grep -i cache
Cache Status: Permanently Disabled
Cache Status Details: Cable Error
Cache Ratio: 10% Read / 90% Write
[sinan]$

There is an Advisory document released by HP: http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c05302924

But I am not sure what to do next. Any suggestions?

Call HPE support.

Most of the times the replacement of the SSB (battery) will solve the issue.

Hello,

Replace the SS battery first, if the problem persists, you need to replace the control card. because the cache module is embedded.
