Syslog error messages

[Ali Imran Abbas]

My syslog in various servers give the following errors some time, any body got an idea who is this all about:

See this doc for explanation:

"...
This tunable notifies the stape driver whether it should allow access to device special files without the no-rewind-on-close option. With this tunable on, the stape driver will fail any open on a stape device special file without the no-rewind-on-close option (i.e., /dev/rmt/1m or /dev/rmt/1mb) with a status of EINVAL.

The st_san_safe tunable allows the safe sharing of tape devices in SAN tape backup solution configurations. The disabling of device special files without no-rewind-on-close in a SAN tape backup solution configuration prevents the accidental sending of a rewind command on close from HP-UX systems via standard tape commands like mt(1) which would corrupt a backup in process"

... so some process on this server is trying to open rewind-on-close device files. My first thought would be some sort of backup software?

Hi Ali,

With this parameter only no-rewind-on-close tape device files can be used.

Please confirm
