According to our engineers it is not a terrible device, but from a
backup perspective it is neigh useless.  Basically we opened a 6 month
long ticket with Sun trying to fix NDMP after we discovered that not
only is performance poor, but if it found a file or folder it didn't
like, it simply skipped it, sending no error to Netbackup or to the NAS
event logs.  We had to run the NDMP service in debug mode and watch the
screen to see the output of what was actually happening.  We finally
switched all our backups over to NFS which crawls along slightly faster
than NDMP and also generally does not skip any files.

Martin,

What was the issue with the Sun StorageTek 5320?

Someone is trying to give me one.

All,

I know there are many Sun aficionados on here and I just wanted to
mention that NDMP on the new Sun Unified platform is apparently broken.
Basically, some backups will work for a while via NDMP but the NDMP
daemon has some sort of memory leak which will eventually lead to error
99s and all backups failing.  The work around so far appears to be
rebooting the storage device, but I haven't confirmed that quite yet. My
testing so far has been on the 7410 series, but I'm about to work on the
7210 as well.  Sun document on the issue is 6787737 and there is
currently no fix available.  My SR# for reference is 70900716.  If this
debacle is anything like the Sun StorageTek 5320 debacle I'm sure plenty
of frustrated admins are trying to troubleshoot this issue as we speak.
I'm just pissed off because I've spent another 2 weeks troubleshooting
ANOTHER Sun storage device that never should have made it past QA.
