Hello oracle-l,
We have an Oracle 11.2.0.2 RAC on a 2-node Solaris 10 cluster on a NetApp
FAS6080. This database is somewhat large, approximately 18 TB. We are using
NetApp Snap Manager 3.1 for online database backups.
We've had two incidents now where the SAN Aggregate for the archive destination
has "filled up", despite the fact that the ASM disk group is only at 50% of
capacity.
Does anyone know of a command-line utility that could give us information on
the status and free space of the aggregate? Our UNIX/Storage admin is "working
on the problem" ... but our wait for a fix or a correction to the configuration
could be quite long. We don't have access to the NetApp tools that are used to
configure and monitor the SAN. I was hoping that there might be something that
could be run that could at least give us a warning when space was becoming an
issue at the aggregate level.
I've tried
$ sanlun lun show -p -v all
and that displays a lot of info, but there appears to be no options with sanlun
that have details on aggregate space.
I did come across this webpage:
http://www.datadisk.co.uk/html_docs/netapp/netapp_disk.htm
http://www.datadisk.co.uk/html_docs/netapp/netapp_cs.htm
Both mention the "aggr" command:
aggr status
aggr status -r
aggr status <aggregate> [-v]
but I can't locate aggr on our Solaris servers.
If anyone has any suggestions, they would be most welcome.
Thanks,
Lou Avrami
