Hi,
I have a script that does a FLASHCOPY, then a "chccwdev -e" against the
newly copied disk. It seemed that the chccwdev command finished
asynchronously. In the past I had a "sleep 1" which seemed to allow enough
time for the command to finish, but I got comments that "udevsettle", or
"udevadm settle" were the preferred method of waiting for chccwdev to
finish. So I now use "udevadm settle" and it seemed to also work fine.
Until today...
I ran the script and it didn't complete for a few minutes. I isolated the
delay to the "udevadm settle" command. Now I run it from the command line
and see:
# time udevadm settle
After the udevadm settle timeout, the events queue contains:
415: /devices/css0/0.0.000d/0.0.1100
416: /devices/css0/0.0.000d
423: /devices/css0/0.0.000d
424: /devices/css0/0.0.000d/0.0.1102

real 3m0.929s

It seems that udevadm settle is timing out after three minutes. Has
anyone seen this, or can explain it? Thanks.

The udevsettle command has a --timeout option according to the man page.
This is probably band-aid for some deeper problem though..
