IO Timeout

Joseph A Benaiah_1 — Fri, 28 Jun 2002 14:37:46 GMT

Dear All,

Is there a default configuration file that HP-UX uses, similar to the disktab file, when a disk is pvcreated.

The reason that I am asking is that I want to set default IO timeout to 180 secs rather than use the default value of 30 secs. I could pvchange that value afterwards but I would prefer to have as default if possible.

Cheers,

Joseph.

No, there is no way to modify the default of 30 secs automatically. The only way is to override it manually after youve done your pvcreate.

The pvcreate command initializes the disk by creating a LVM header on the disk and it does not reference "disktab" like information to do this. The only way I know is using the pvchange (-t option) to change your timeout value after your disk has been pvcreated.

The default value is controlled by the individual driver - there's no single default value.
