pvdisplay

Martin Wells — Mon, 16 Jun 2003 09:33:33 GMT

We have been getting several disk failures on one of our L-class servers running HPUX11. When it happens pvdisplay and vgdisplay commands stop working and when ioscan is run our weblogic webserver falls over. The disks are connected via fibre channel connections. We have had four disk failures in the last week?

Hi,
what kind of HW failure are you getting ?
If you find something from your dmesg, this can help.

But it's best to open an HW call.

If failures are coming from all the disks, chances are that are not the disks but the FC, or even the driver.

HTH,
Massimo

Get all your fibre channel cards up to date on patch levels, and also try to drop and restart both ends of the fibre channel connection (router and card).

If you are running EMC disks, have you adjusted the disk timeout value?

Share and Enjoy! Ian

Hi Martin

What sort of FC array are you using?

Is it the same disk that fails or different disks on the array?

Cheers

George

What kind of failure is it?

What does the syslog say? dmesg?
