Slept from ten-thirty to seven. Woke briefly around two.
High of sixty-nine and scattered showers today.
Stopped at Starbucks on my way to work.
Work:
- Clean-up breakage from last night's upgrades
Mostly done.
A hectic morning. VPN troubles.
HP server with hardware RAID.
Complaints from smartd.
`/dev/sda` is the logical volume from the RAID, not the physical drives.
Can it see the SMART status of the physical disks through the RAID?
What is `/dev/sg0`?
The `sg` devices are "SCSI generic".
From `smartctl(8)`:
> cciss,N - [FreeBSD and Linux only] the device consists of one or more SCSI/SAS or SATA disks connected to a cciss RAID controller. The non-negative integer N (in the range from 0 to 15 inclusive) denotes which disk on the controller is monitored.
> To look at disks behind HP Smart Array controllers, use syntax such as:
> smartctl -a -d cciss,0 /dev/sg2 (hpsa or hpahcisr drivers under Linux)
So:
```
--- kosmokrator ~ $ sudo smartctl -a -d cciss,0 /dev/sg0
[...snip...]
--- kosmokrator ~ $ sudo smartctl -a -d cciss,1 /dev/sg0
[...snip...]
--- kosmokrator ~ $ sudo smartctl -a -d cciss,2 /dev/sg0
[...snip...]
--- kosmokrator ~ $ sudo smartctl -a -d cciss,3 /dev/sg0
[...snip...]
--- kosmokrator ~ $ sudo smartctl -a -d cciss,4 /dev/sg0
[...snip...]
