Hi
I have a Solaris 8 box that is mirrored using Solstice Disk Suite which
we backup every night. With this type of scenario we have to break the
mirror, do the backup and then re-attach the mirror again .....we do
this on multiple boxes with no problems, however with this box we get
this strange error at the end
d30: submirror d32 is offlined
DUMP: Writing 63 Kilobyte records

/data1: Deadlock situation detected/avoided email_alert
Sun say that " This error usually relates to file and record locking,
but can also apply to mutexes, semaphores, condition variables, and
read/write locks."
However this doesn't really help identify what file is deadlocking or
causing the problem, has anybody experienced this type of thing before
?, it doesn't actually seem to be causing any problems with the
operation of the machine, but for all the boxes we backup like this,
this is the only one that gives me this error
Any help on this would be greatly appreciated
Cheers
Gary
