Hi,
I have a LSI Logic sata/sas raid running, is there a way to see
the state of
the volume, like optimal, degraded or resyncing?
There is sysutils/linux-megacli
Sorry about that. This is not megaraid its the mpt driver.
LSI SAS3041E-R PCI-e
mpt0: <LSILogic SAS/SATA Adapter> port 0x2000-0x20ff mem
0xd0210000-0xd0213fff,0xd0200000-0xd020ffff irq 16 at device 0.0 on
pci3
mpt0: [ITHREAD]
mpt0: MPI Version=1.5.19.0
mpt0: Capabilities: ( RAID-0 RAID-1E RAID-1 )
mpt0: 1 Active Volume (2 Max)
mpt0: 2 Hidden Drive Members (14 Max)
While I haven't found a way to actually configure the thing in
FreeBSD, the mpt
driver does make some information available via sysctl:
[sp...@uniweb ~]$ sysctl -a|grep dev.mpt
dev.mpt.0.%desc: LSILogic SAS/SATA Adapter
dev.mpt.0.%driver: mpt
dev.mpt.0.%location: slot=8 function=0
dev.mpt.0.%pnpinfo: vendor=0x1000 device=0x0054 subvendor=0x1028
subdevice=0x1f09 class=0x010000
dev.mpt.0.%parent: pci2
dev.mpt.0.debug: 3
dev.mpt.0.role: 1
dev.mpt.0.vol_member_wce: NC
dev.mpt.0.vol_queue_depth: 128
dev.mpt.0.vol_resync_rate: 0
dev.mpt.0.nonoptimal_volumes: 0
Don't test whether the "nonoptimal_volumes" parameter works, it does -
but if you pull a drive, FreeBSD likes to panic both on the loss of a
disk
and then again when the drive is reconnected and the rebuild completes.
This is apparently some problem in the CAM layer, not the mpt driver,
but
it's something to be aware of. Scott Long has noted that this is being
worked on in 8.x.
