We've been having some weird issues where a single drive failure causes
problems all over the place. In one case we lost an entire mirror set
(running in split loop configuration), and recently a single drive failure
causes disk groups to take 20-30 mins to import/export (even disk groups
that didn't have this drive). Additionally, luxadm display would hang on
displaying that particular array. Sun said
"any components/node in the loop will be affected by a failure and will
cause the loop to respond slower/ sometimes not responding (meaning
hanging)."
But I don't buy that, since we never had disk failures cause so many
problems before.
Additionally, Sun is complaining about us running an 'unsupported sun
config' (we have 4 a5200's instead of 3 they say we can have max).
Another issue that we are researching, is that one of the disk arrays
might have non-sun drives (e.g. seagate disks put into sun shells),
therefore we want to update the firmware on those drives. The problem is,
we need to know the model numbers of drives in order to get the latest
patches from Sun site.
Anybody knows how to do that from shell? Any other ideas would be
appreciated.
Our setup:
3xe4500, 4 Sun FC 8 port hubs, 4 disk arrays, split loop config (front
loop, rear loop)
Thanks.
