vxdump

[Angela Swyers_1]

We are using vxdump to do a backup of our system. We have 2 mount points that fail. They are a vxfs filesystem and we get the following errors:

vxdump: 57.19% done, finished in 0:33
vxdump: Closing /dev/tapen
vxdump: Change Volumes: Mount volume #2
vxdump: fopen on /dev/tty fails: No such device or address
vxdump: The ENTIRE dump is aborted.

vxdump -0u -f /devtapen /exp01

We are running HP-UX 11.00.

Any ideas?

Is the system a heavily used (many many users)? You may want to look at your pty kernel settings nstrpty/npty?

Are you running this manually or from cron?

Vxdump is interactive - if from cron - sounds like you ran out of tape.

Get a bigger tape drive or stageer the backups so you can change the tape.

Or resize your volume to fit on one
tape or buy a tape library and backup software that supports unattended
backups.

Angela, you did not mentin if this vxdump job is run out of a script thorugh job scehduler (cron, at, batch or wahetever)... If that's the case .. then yes as Geoff points out.. it is simply a matter of you failing to provide a another tape to continue the backup.

Is this the 1st time you exceeded the size of your tape? If you've set up your system so it has an "operator" account - the operator on the console should see a request for a tape mount.
