HOWTO

Virtual Devices

storcli /c0/v1 set name=myname

note: do not confuse VG with DG

Create mirror

storcli /c0 add vd type=r1 drives=15:8,12

Create RAID 10 device

storcli64 /c0 add vd type=r10 drives=252:4-7 pdperarray=2

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


Identify disks

lsblk -dno name,hctl
# 0:0:24:0

Third number is the DID from storcli /cX show



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
  • 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

VD settings with SSD

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

Error messagess

Description = physical disk does not have appropriate attributes

Does it happen to show DG as "F"? try 

storcli /c0/fall show

and 

storcli /c0/fall delete

Also set to UGood

Description = operation not possible for current RAID level, Cannot create configuration with 1 span

You might want to check for pdperarray
