I have a disk that is periodically throwing not ready errors and threw a SAS bus error yesterday. The filer has not failed the disk yet, but it throws a clump of not ready errors every few hours. I can live with occasional not ready errors but not a SAS error (it also triggered an autosupport):

I'd tried "disk maint start" but nothing happens:
> disk maint start -d 1c.02.17

I have 5 spares and my options appear to be set correctly:
| disk.maint_center.allowed_entries 1 |
(value might be overwritten in takeover) |
|
| disk.maint_center.enable |
on |
(value might be overwritten in takeover) |
| disk.maint_center.max_disks 84 |
(value might be overwritten in takeover) |
|
| disk.maint_center.rec_allowed_entries 5 |
(value might be overwritten in takeover) |
|
| disk.maint_center.spares_check on |
(value might be overwritten in takeover) |
|
| disk.recovery_needed.count 5 |
(value might be overwritten in takeover) |
(I don't know what this is but I think it's a cluster param)
|
Meanwhile I will try to fail the disk to a spare and swap it out, it would be nice to maint test the disk, which includes a power cycle and might either mark the disk as truly bad or clear the problem (or maybe crash the SAS bus, who knows...). I don't have any remote hands to physically pull it and reseat it or I'd just do that.
Does anyone know what the "disk maint: Maximum number of disks testing" message means?
Thanks,w
