Question on pvlink

[Jimmy Tom_1]

I am trying to determine how to tell when
the primary pvlink failed on HP-UX 11.0.

Is a logfile entry created when the alternate
pvlink is used because the primary pvlink
failed? What is the errorlog file name?

Thanks.

I believe that you will get an appropriate message in the syslog (/var/adm/syslog/syslog.log) and also in the kernel's console message buffer (viewable with dmesg).

The former will have a date/time stamp, the latter will not.

when there is a failure in the primary link you will get the following error in the /var/adm/syslog/syslog.log file. The same message will appear even when you try to remove the primary link form the volume group.

When there is a pvlink failure, you will have a error reported on /var/adm/syslog/syslog.log file and also error is displayed on console.
