HOWTO
Add new/replacement disk
Show all should tell you s(Slot), dg, array and row, then:
storcli /c0/e32/s12 insert dg=0 array=0 row=0 storcli /c0/e32/s12 start rebuild
Locate a disk
storcli /c0/e8/s2 start locate
Show rebuild status
storcli /c0 /eall /sall show rebuild
Drive mappings
sg_map -x
Output: /dev/sgXX <host_number> <bus> <scsi_id> <lun> <scsi_type>
/dev/sg11 7 0 1 0 0 /dev/sdl
<scsi_id> is VD in storcli output, this is not always same as DG :)
TODO find out where that '7' comes from
Alarm
Silence alarm
storcli /c0 set alarm=off
BBU
Show time
storcli /c0 show time
Get BBU status
storcli /cx/bbu show all
BBU start learn
storcli /cx/bbu start learn
BBU status values
Check here for more confusion
- 0: OK
- 8: charging or not full, unclear
- 16: cachevault?
- 32: manual learn requested
Get smart status of disk
/dev/bus/0 -d sat+megaraid,14
Where 14 is disk ID, not Slot number
Set disk to JBOD
If disk still in an array, first delete that :)
storcli /cx[/ex]/sx set jbod
If that fails try:
storcli /c0 jbod=on
this might/should set all unused drives to jbod
Else look at:
storcli /c0/e9/s0 start erase simple
or if that fails
storcli /c0/e9/s0 start erase
this takes a while, check with
storcli /c0/e9/s0 show erase
FAQ

storcli /c0/fall del
Virtual Devices
NRWBD
NR=No Read Ahead WB = Write Back D = Direct IO
Cache settings
read ahead
usually on, pointless i reads are very random
write back
Faster, assumes you have BBU
FAQ
List controllers
storcli show all
VD settings with SSD
NO read ahead, write through
storcli /c0 /v2 set wrcache=wt
No read ahead
storcli /c0 /v2 set rdcache=nora
Changing cache settings
storcli /c0 /v1 set wrcache=wt|wb|awb storcli /c0 /v1 set rdcache=ra|nora
ErrMsg: use /cx/cv
There migh be a "cachevault"?
storcli /c0/cv show status
