hi chris, these commands should help you get a little better acquainted with your new NetApp system.
aggr status //show aggregate info; use '-i' to show volumes within each aggregate aggr show_space //show aggregate storage capacity details and volume to aggr space relationship sysconfig //shows system details; use '-r' for raid group info; use '-v' for verbosity
snap sched //shows snap shot schedule and retention for volumes; use '-A' for aggr sched snap list //shows list of snapshots for volumes and aggr; use '-A' for aggr list
df //show vol space capacity details; use '-i' for inode info; use '-r' for snap reserve info; use '-A' for aggr info lun show //list of luns; use '-v' for more details igroup show //list of initiator groups containing san host info
fcp show initiators //list of fcp adapters and initiators connected to them
sysstat //shows system utilization
you should also be able to browse around within the OpsMgr web interface and find system info. there's the management console too that you can install on another machine to connect to the DFM server.
Spend some time with DFM web page i.e. operations manaager and you can get all the information the only thing which you will not get is last accessed, as this needs crawling through all the data and checking file properties which DFM doesn't do unless you have license for FSRM which is discontinued now.
back from the dead (thanks Google). I would like to find this out as well. We had a few too many irons in the fire and now we have volumes that we have no idea if they are being accessed. We dont think they are, as there are no exports, references (etc etc), but would like to be sure.
