Under the linux system, the disk is replaced, but for the HP array card, the common MegaCli, storcli and percli can not get the disk information. At this time, the special tool ssacli is needed.

View raid card information (including controller status, Cache status, battery status)
# ssacli ctrl all show status
View raid details
# ssacli ctrl slot=0 show config detail
View raid status
# ssacli ctrl slot=0 ld all show
View all logical drive information of slot 0 array A
# ssacli ctrl slot=0 array A ld all show
View all physical drive information of slot 0 array A
# ssacli ctrl slot=0 array A pd all show
View hard disk
#ssacli ctrl slot=0 pd all show status / / view the physical hard disk status #ssacli ctrl slot=0 pd all show / / view the physical hard disk
Create raid10
# ssacli ctrl slot=0 create type=ld drives=1I:1:3,1I:1:4,2I:1:5,2I:1:6 raid=1+0
Create a raid5 array with disks 3, 4 and 5
# ssacli ctrl slot=0 create type=ld drives=1I:1:3,1I:1:4,2I:1:5 raid=5
Create raid1
# ssacli ctrl slot=1 create type=ld drives=1I:1:1-1I:1:2 raid=1
Delete raid
# ssacli ctrl slot=1 array B delete forced
Cache:
To view cache information:
# ssacli ctrl all show config detail | grep -i cache
Turn off physical disk cache
# ssacli ctrl slot=0 modify drivewritecache=disable
Open Logical Disk Cache
# ssacli ctrl slot=0 logicaldrive 2 modify caching=enable
Enable raid write cache without battery
# ssacli ctrl slot=0 modify nobatterywritecache=enable
Set read / write percentage
# ssacli ctrl slot=0 modify cacheratio=10/90
indicator light:
Turn on the led light of array B disk
# ssacli ctrl slot=0 array B modify led=on
Turn on the led light of disk 3
# ssacli ctrl slot=0 pd 1I:1:3 modify led=on
