VxVM disk/lun grow
hi,
i have a volume on a LUN of an EMC-storage and i need to increase the
size.
i could increase the size of the LUN on the EMC, i could increase the
size of the disk for solaris, but how can i tell the veritas volume
manager that the disk is larger now?
what i've done:
1. LUN on EMC
2. in the format menue i' ve chosen the type to autoconfigure, i can see
the bigger disk in solaris, then in the partitions menu i've created the
VTOC like before, only one slice on 7 (and 2 for backup, like before) for
the whole space.
but VxVM still means
# vxassist -g datadg maxsize
VxVM vxassist ERROR V-5-1-752 No volume can be created within the given
constraints
# vxassist -g datadg maxgrow datavol
VxVM vxassist ERROR V-5-1-1178 Volume datavol cannot be extend within the
given constraints
so i tried "vxdctl enable", but still the same... but i can still work
with the volume.. it must be written in the privatregion somewhere...
any ideas?
V440, solaris9 (09/05), VxVM 4.1, VxFS 4.1
thanks in advance,
PRESSY

pfto(7) Miscellaneous Information Manual pfto(7)
NAME
pfto - Powerfail Timeout
DESCRIPTION
HP-UX SCSI disk device drivers have a timeout facility that detects non-responding disks. VxVM uses this mechanism in its Powerfail Time-
out (pfto) feature. You can specify a timeout value for individual VxVM disks using the vxdisk command (see the EXAMPLES section below).
If a disk fails to respond in the specified timeout period, the driver receives a timer interrupt.
pfto values are persistent across reboots, that is, after the pfto value is set, it remains in effect until you explicitly change it. If
dynamic multipathing is enabled, the pfto value set on a disk applies to each path of a multipath disk device.
The pfto value is in seconds. If pfto is not specified, or is zero, the timeout period is 30 seconds. Both the vxdisk and vxprint commands
display the current pfto value for a disk.
EXAMPLES
Use the following command to set the value of pfto to 30 seconds on disk01:
vxdisk -g rootdg set disk01 pfto=30
Use either of the following commands to display the pfto value on the VxVM disk disk01:
vxdisk list disk01
vxprint -l disk01
EXIT CODES
Setting the pfto value on a non-VxVM disk returns an error.
