We've started having a few issues of last with SDU (4.2P2) running very slowly on one of our HPUX boxes. We're using SMO, but I'm fairly sure the issue is with SDU rather than SMO.
Running simple snapdrive commands such as snapdrive storage show, or snap create can take a long time to complete. Last night, for example, the SMO log show the snap create command taking >2hours!! As you can see below it take nearly half an hour to do a snapdrive storage show command.
The problem is much worse overnight where there are a lot of SMO jobs running (there are ~50 oracle DB's on this box). Has anyone out there seen anything similar before?
