vxpfto

NAME

vxpfto - set Powerfail Timeout (pfto)

SYNOPSIS

DESCRIPTION

Powerfail Timeout is an attribute of a SCSI disk connected to an HP-UX host (see the pfto(7) man page). The vxpfto command sets the Powerfail Timeout interval on a set of Volume Manager disks, either all disks in a disk group, or all disks underlying the volumes listed.

The first form of the command sets the same PFTO value for all the disks in the specified VxVM diskgroup.

In the second form, all disks underlying the given list of volumes are selected, optionally restricted by the disk group specified with the -g option. If you specify a diskgroup, any volume in the list not belonging to the diskgroup is ignored.

If you invoke vxpfto without arguments, it displays a usage message.

OPTIONS

-g diskgroup

Specifies the disk group for the operation, either by disk group ID or by disk group name.

-t timeout

Specifies the PFTO value in seconds. This option is required. The value must be zero or a positive integer. Zero represents the system default PFTO value. The default value depends on the disk driver controlling the disk device.

volume_list

A list of VxVM volume names. List items must be separated by white-space.

EXIT CODES

vxpfto returns a zero if successful. If it encounters an error, vxpfto exits and displays a message on standard error. Defined exit codes are:

0

Success.

1

No PFTO value specified.

2

No diskgroup or volume list specified.

3

Illegal PFTO value specified.

EXAMPLES

Set the PFTO value on all disks in disk group testdg to 100 seconds:

Set the PFTO value to 50 seconds on all disks underlying volume01 and volume02 in disk group testdg:

Set the PFTO value to 300 seconds on all disks underlying volume01 and volume02, even though they are not in the same disk group:
