change of SCSI ID
suddenly found that the SCSI ID of a direct attached SCSI Tape Drive was changed on a HPUX 11.31 system.
anyone can help? since i have no idea why the SCSI ID has been changed.
i have run "Bastille" to hardening the HPUX system, will that be the case?
thx so much.
b.r.

Re: change of SCSI ID
check the time stamp of these file.
Can you show us /dev/rmt?
Normally /dev/rmt/0m is created the first time a tape is configured to a system.
When other tapes are added, then 0 is counted up to 1, then 2 ...
Maybe after reboot the system recognized, that 0 was no longer used ...
