NAME
vxpfto — set Powerfail Timeout (pfto)
SYNOPSIS
vxpfto -g diskgroup -t timeout
vxpfto [-g diskgroup] -t timeout volume_list
DESCRIPTION
Powerfail Timeout is an attribute of a
SCSI disk connected to an HP-UX host
(see
pfto(7)).
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:
vxpfto -t 50 -g testdg volume01 volume02
Set the PFTO value to 300 seconds
on all disks underlying volume01 and volume02,
even though they are not in the same disk group:
vxpfto -t 300 volume01 volume02
