This tool is a proprietary one created by HP. It can do both reporting and management.
\n3.2.1. Quickstart guide<\/p>\n

List all controllers:<\/p>\n

server:~# hpacucli controller all show<\/p>\n

Smart Array 6i in Slot 0 ()<\/p>\n

List arrays on controller in slot 0:<\/p>\n

server:~# hpacucli ctrl slot=0 logicaldrive all show status<\/p>\n

logicaldrive 1 (33.9 GB, RAID RAID 1+0): OK
\nlogicaldrive 2 (136.7 GB, RAID RAID 1+0): OK<\/p>\n

I don’t know why it reports RAID 1+0. This is regular RAID1 arrays.<\/p>\n

List physical drives on controller in slot 0:<\/p>\n

server:~# hpacucli ctrl slot=0 pd all show status<\/p>\n

physicaldrive 1:0 (port 1:id 0, 36.4 GB): OK
\nphysicaldrive 1:1 (port 1:id 1, 36.4 GB): OK
\nphysicaldrive 1:2 (port 1:id 2, 146.8 GB): OK
\nphysicaldrive 1:3 (port 1:id 3, 146.8 GB): OK<\/p>\n

Summarized status:<\/p>\n

server:~# hpacucli ctrl slot=0 show config<\/p>\n

Smart Array 6i in Slot 0 ()<\/p>\n

array A (Parallel SCSI, Unused Space: 0 MB)<\/p>\n

logicaldrive 1 (33.9 GB, RAID 1+0, OK)<\/p>\n

physicaldrive 2:0 (port 2:id 0 , Parallel SCSI, 36.4 GB, OK)
\nphysicaldrive 2:1 (port 2:id 1 , Parallel SCSI, 36.4 GB, OK)<\/p>\n

array B (Parallel SCSI, Unused Space: 0 MB)<\/p>\n

logicaldrive 2 (136.7 GB, RAID 1+0, OK)<\/p>\n

\nphysicaldrive 2:3 (port 2:id 3 , Parallel SCSI, 146.8 GB, OK)<\/p>\n

Controller policies (write cache, disk cache, battery), only interesting lines kept:<\/p>\n

Smart Array P420i in Slot 0 (Embedded)
\nSerial Number: *SERIAL*
\nController Status: OK
\nFirmware Version: 3.54
\nCache Board Present: True
\nCache Status: OK
\nCache Ratio: 25% Read \/ 75% Write
\nDrive Write Cache: Disabled
\nTotal Cache Size: 512 MB
\nNo-Battery Write Cache: Disabled
\nCache Backup Power Source: Capacitors
\nBattery\/Capacitor Count: 1
\nBattery\/Capacitor Status: OK<\/p>\n

Cache is ok, Battery is too. Write cache disabled if battery back isn’t enabled, that’s ok.<\/p>\n

Check and enable cache for all arrays:<\/p>\n

Check current state:<\/p>\n

root@server:~# hpacucli ctrl slot=0 ld all show detail<\/p>\n

Smart Array P420i in Slot 0 (Embedded)<\/p>\n

array A<\/p>\n

Logical Drive: 1
\nSize: 136.7 GB
\nFault Tolerance: RAID 1
\nStatus: OK
\nCaching: Disabled<\/p>\n

Enable caching:<\/p>\n

root@server:~# hpacucli ctrl slot=0 ld all modify arrayaccelerator=enable<\/p>\n

Enable disks’ write cache:<\/p>\n

root@server:~# hpacucli ctrl slot=0 modify dwc=enable<\/p>\n

Warning: Without the proper safety precautions, use of write cache on physical
\ndrives could cause data loss in the event of power failure. To ensure
\ndata is properly protected, use redundant power supplies and
\nUninterruptible Power Supplies. Also, if you have multiple storage
\nenclosures, all data should be mirrored across them. Use of this
\nfeature is not recommended unless these precautions are followed.
\nContinue? (y\/n) y<\/p>\n

Warning is self-explaining I guess. Disks’s cache aren’t protected by controller’s battery. It’s up to you but I wouldn’t enable such features if your power supply isn’t protected.<\/p>\n

Modify cache ratio between read and write:<\/p>\n

root@server:~# hpacucli ctrl slot=0 modify cacheratio=50\/50<\/p>\n
