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> <disk>

/dev/sg11  7 0 1 0  0  /dev/sdl

<scsi_id> is VD(DID?) 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

BBU status values

Check here for more confusion

• 0: OK
• 8: charging or not full, unclear
• 16: cachevault?
• 32: manual learn requested
• 40: learning?
• 112: discharging for learning cycle?

BBU status values

Dec	Binary	Hex	Description
8	1000	0x08	charging?
16	10000	0x10	discharging?
32	100000	0x20	Learn Cycle Requested
64	1000000	0x40	Learn Cycle Active
1024	10000000000	0x400	Replace battery
2024	100000000000	0x800	Total failure to communicate with BBU
2152	100001101000	0x868	??

Get smart status of disk

/dev/bus/0 -d sat+megaraid,14

Where 14 is disk ID (DID), not Slot number

Set disk to JBOD

If disk still in an array, first delete that :) Looks like disks should be in state UGood

storcli /cx[/ex]/sx set jbod

If that fails try:

storcli /c0 set 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

Failure 255 Operation not allowed.

Disk still in an array?

Output

UGood F

Disk contains foreign config, clear with

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

Set bootable

storcli /c0/e10/s0 set bootdrive= on|off

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
