where did file /usr/tmp/rdskGKAa05924 come from?

[Curtis Whitworth]

Folks,
After our last reboot, I had a couple of new special files on our system (V2500, HP-UX 11.0):
crw------- 1 root root 203 0x016000 Apr 8 19:06 /usr/tmp/rdskGKAa05924
crw------- 1 root root 203 0x016000 Apr 8 19:06 /var/tmp/rdskGKAa05924

We had not added any new hardware, or applied any patches, or installed any new software, so I'm just curious as to where they might have come from. I could not find any info on special files with major numbers of "203". Any ideas???

Hi:

You can do an lsdev (no args) to find the drivers associated with 203. It's actually the sctl (SCSI Control Pass-thru) driver. I suspect those are simply temporary device nodes left over from device scan. SAM will occasionally leave temp files like that when attempting to 'Diagnose Missing Devices'.

You can delete those device nodes.

203 is a valid major number actually.

# lsdev|grep 203
Character Block Driver Class
203 -l sctl ctl

scsi controller I suppose. The other part of yr question ... "where did they come from".. I'm not sure.

Would it be ok to remove these files, as they accumulate over time? Thanks,

It make sense what Clay has just said, if those are "residue" by SAM then yes you can .. use rmsf

# cd /usr/tmp
# rmsf rdskGKAa05924
