Just a poll to see who attempts to disconnect/unmount every possible client (server) before attempting a DataONTAP upgrade and who types download; reboot.
Does anyone leave their Oracle databases mounted via NFS over UDP up the whole time?
Heavens, we always sync Oracle. On production DBs where we can't afford a full shutdown/restart cycle, I think the DBA puts it in hot backup mode (even when I'm about to replace a disk, just on the off-chance that something goes haywire) and the reboot cycle is quick enough that things just come right back. When we can afford the downtime, however, it is preferable to shut Oracle down properly, reboot, then bring it back up.
But for normal NFS clients on filers not serving databases we just bounce 'em. Y'know, the once a year or so that it's necessary:
4:37pm up 234 days, 1:44 2026468359 NFS ops, 0 CIFS ops, 0 HTTP ops, 0 DAFS ops 4:37pm up 255 days, 20:47 1725238310 NFS ops, 18226083 CIFS ops, 0 HTTP ops, 0 DAFS ops 4:38pm up 58 days, 3:12 31217232 NFS ops, 0 CIFS ops, 0 HTTP ops, 0 DAFS ops
(Okay, on that last one, let me tell you about the fun we had when the UPS technician came out and the transfer switch... didn't...)

Hey, what's that command to have ONTAP print out uptime stats? availsomething? I'm curious to see what our stats have been over the last three years.
