I'm trying to monitor hardware RAID status on HP ProLiant DL180 G6 with "cciss_vol_status" tool.
Unfortunately, on some of my servers it can't decide if the array is healthy or not (or, the spares in it).
For example, it outputs the following failures about the spares:
# cciss_vol_status /dev/cciss/*
/dev/cciss/c0d0: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d0: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive has failed.
Total of 1 failed physical drives detected on this logical drive.
/dev/cciss/c0d0: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
/dev/cciss/c0d0p1: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d0p1: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive has failed.
Total of 1 failed physical drives detected on this logical drive.
/dev/cciss/c0d0p1: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
/dev/cciss/c0d0p2: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d0p2: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive has failed.
Total of 1 failed physical drives detected on this logical drive.
/dev/cciss/c0d0p2: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
/dev/cciss/c0d1: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d1: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive has failed.
Total of 1 failed physical drives detected on this logical drive.
/dev/cciss/c0d1: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
But start it again short after "the failed run", and it will report no failures at all:
# cciss_vol_status /dev/cciss/*
/dev/cciss/c0d0: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d0: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive remains available.
/dev/cciss/c0d0: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
/dev/cciss/c0d0p1: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d0p1: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive remains available.
/dev/cciss/c0d0p1: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
/dev/cciss/c0d0p2: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d0p2: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive remains available.
/dev/cciss/c0d0p2: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
/dev/cciss/c0d1: (Smart Array P410) RAID 1 Volume 0 status: OK.
/dev/cciss/c0d1: (Smart Array P410) RAID 5 Volume 1 status: OK. At least one spare drive designated. At least one spare drive remains available.
/dev/cciss/c0d1: (Smart Array P410) Enclosure DL18xG6BP (S/N: ) on Bus 0, Physical Port 1I status: OK.
Wait a few minutes, it will report failures.
Is it expected? Are my spares failing or not?
I'm running 64 bit Debian Lenny (2.6.26 kernel).
PS. is there a better list for Linux hardware RAID issues?
