Anyone got any thoughts on why disks on a HSZ70 controller pair would suddenly start throwing disks into mount verification?
One particular disk is reproducible in that if you run ANALYZE/DISK across it, it'll repeatedly go into mount verify.
A disk that was replaced (on the assumption that it had failed) spent about 2 days online, then again went mount verify, timed out, then offline. It still mounts on the other host on the shared bus quite happily.
VMS v6.2-1h3, 2 off AS4100, HSZ70 pair between the hosts.
The systems have been happy as a happy thing until this spurt of disk issues. |

Doesn't sound like the disk at this point. If this is the only one affected, then look at anything else unique to this drive. Perhaps a bad tray slot, controller or even a marginal power supply. Try swapping parts around. See what changes or moves.

Thanks Dan.
It turned out that one of the disks was part of a stripeset with one failed disk. I still haven't got to the bottom of the disk that went mount verify and then timed out. At the moment, it seems fine so I'm keeping my head down! |

You've just experienced warnings of imminent hardware failure. Make sure backups are up-to-date and starting implementing a storage replacement plan. |
