Message in the syslog.log

[Giada Bonfà]

Hi,
I've this message in the syslog:
cmclconfd[26856]: Unable to open disk /dev/dsk/c3t2d0: Device busy.

/dev/dsk/c3t2d0: this is the device file of a DVD-ROM.
What does it mean?
Thank you!

[Bill McNAMARA_1]

is it mounted and in your /etc/fstab?

Later,
Bill

Hi


I believe that this is caused by cmclconfd trying to access the shown device, in order to read LVM/VXCM info from it.


If the message appears only by reboot I would ignore it as a warning which has no real use but is better than a hang.

No, it isn't mounted and it isn't in the /etc/fstab.

Hi,
To stop that error message
# fuser -k /dev/dsk/c3t2d0

Hi Giada,

cmclconfd is the ServiceGuard configuration daemon. It's used to gather info on all nodes in the cluster.
Is it possible that someone was configuring/reconfiguring the cluster at that time?
If you do not run MC/SG on this system I suspect that some "accidently" ran cmcheckconf or possibly even cmapplyconf.
If you do run MC/SG then you may want to check that no cluster aware VGs mistakenly have this device included nor that this dev has not been designated as a lock disk or that any pkg def has this VG defined w/in it.

Rgds,
Jeff

Hi Giada,

Is this message seen in syslog only once or every now and then.

Hope this helps.

I run MC/SG and I had the message only once in the syslog of both the cluster's nodes.
Regards.
