    Hi

    SunOS xxx 5.9 Generic_112233-04 sun4u sparc SUNW,Sun-Fire-480R:

    Yesterday, one disk of an Solaris-9 SVM (SDS in previos releases) mirror
    failed:

    Jan 20 20:20:44 xxx scsi: [ID 107833 kern.warning] WARNING: /pci@8,600000/pci@1/scsi@5/sd@a,0 (sd25):

    Jan 20 20:46:17 xxx md_stripe: [ID 641072 kern.warning] WARNING: md: d62: write error on /dev/dsk/c3t10d0s7
    Jan 20 20:46:18 xxx md_mirror: [ID 104909 kern.warning] WARNING: md: d62: /dev/dsk/c3t10d0s7 needs maintenance

    I mounted the failed disk to /mnt, touch a file, umount. It seems ok.

    I invoked "metareplace -e d60 c3t10d0s7" to enable the submirror and
    resync it to see if it fails again, and after 5-10 minutes it failed:

    Jan 21 15:52:50 xxx md_stripe: [ID 641072 kern.warning] WARNING: md: d62: write error on /dev/dsk/c3t10d0s7
    Jan 21 15:52:55 xxx md_mirror: [ID 104909 kern.warning] WARNING: md: d62: /dev/dsk/c3t10d0s7 needs maintenance

    No other errors in /var/adm/messages (bad-blocks or so). Other times that
    a disk failed, in an other server, there were errors about bad blocks in
    the messages file and "metareplace -e" worked for a while (some days)
    before the mirror failed again (I dont have spare disks, and in the mean
    time I prefer a bad mirror than no mirror)

    How can I check if is a disk problem or a SCSI bus problem?
