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 DG in storcli output

TODO find out where that '7' comes from

storcli /c0 set alarm=off

write back

Faster, assumes you have BBU

FAQ

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
