Kill HUNG ioscan Process

Cliff Lim Kok Hwee — Tue, 14 Sep 2004 22:27:12 GMT

Gd Day Forum,

I just run the command ioscan -fH 0/5/0/0 and it appears HUNG.

The hardware path 0/5/0/0 is attached with tape drives.

I tried performing kill -9 but to no avail.

Can anyone advise me?

thanks n regards/cliff

If you can't hack it out of memory with ipcrm, a reboot will get it out. (Not a great solution, but sometimes the only one)

IPL'ing your tape drive or tape library should actually terminate the process.

Depending on the type of connection, you could conceivably unplug the connection, but rebooting the system should always be a last resort.

Hi Forum,

I performed ioscan -funC tape and realised that some tape drives were showing status "CLAIMED" and some tape drives were showing status "SCAN" on hardware path 0/5/0/0.

I monitored a while and realised now all the tape drives are showing status "CLAIMED".

I performed ps -ef |grep ioscan and now it is gone.
