When I list the PV's using lspv i see both vpath and hdisk names being listed. I got the info that each vpath is configured for 4 hdisks. Problem is I am not able to add either the hard disks in vpath to the existing non-rootvg. ? need to know the basics of vpath .. (4 Replies)
Hi,
in an environment with svc's and ds8xxx wat disk algorithm should be used and what is the difference here:
I can set the algorithm to Load_balance and to Round_robin (see output below).

How do you create a dummy hdisk with AIX 6.1? In previous versions, I've used this and works, but now I get this error.

Hi,
Planning to implement script to fetch whether the hdisks are in proper sequence. Need output for incorrect sequence
Correct
#lspv
hdisk0
hdisk1
hdisk2
::::::::::::
hdisk5
Incorrect sequence
#lspv
hdisk0
hdisk6
hdisk7
hdisk10
Any idea pls share (2 Replies)
Hello,
I have two hdisk in Power7 machine, the rootvg on hdisk0.
So to make a disk redundancy should make mirror or alt_clone and what is the different.
Appreciate your help
Thanks (1 Reply)
Hi everybody,
I have Power5 server with 4 internal hdisks each of 70Gb.
VIOS server was installed via Virtual I/O Server Image Repository on the HMC.

lvresize
LVRESIZE(8) System Manager's Manual LVRESIZE(8)NAME
lvresize - resize a logical volume
SYNOPSIS
lvresize [--alloc AllocationPolicy] [--noudevsync] [-i|--stripes Stripes [-I|--stripesize StripeSize]] {[-l|--extents [+|-]LogicalEx-
tentsNumber[%{VG|LV|PVS|FREE|ORIGIN}] | [-L|--size [+|-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]} [-f|--force] [-n|--nofsck] [-r|--resizefs]
LogicalVolume{Name|Path} [PhysicalVolumePath[:PE[-PE]]...]
DESCRIPTION
lvresize allows you to resize a logical volume. Be careful when reducing a logical volume's size, because data in the reduced part is
lost!!! You should therefore ensure that any filesystem on the volume is shrunk first so that the extents that are to be removed are not
in use. Resizing snapshot logical volumes (see lvcreate(8) for information about creating snapshots) is supported as well. But to change
the number of copies in a mirrored logical volume use lvconvert(8).
OPTIONS
See lvm(8) for common options.
-f, --force
Force resize without prompting even when it may cause data loss.
-n, --nofsck
Do not perform fsck before resizing filesystem when filesystem requires it. You may need to use --force to proceed with this option.
-r, --resizefs
Resize underlying filesystem together with the logical volume using fsadm(8).
-l, --extents [+|-]LogicalExtentsNumber[%{VG|LV|PVS|FREE|ORIGIN}]
Change or set the logical volume size in units of logical extents. With the + or - sign the value is added to or subtracted from
the actual size of the logical volume and without it, the value is taken as an absolute one. The number can also be expressed as a
percentage of the total space in the Volume Group with the suffix %VG, relative to the existing size of the Logical Volume with the
suffix %LV, as a percentage of the remaining free space of the PhysicalVolumes on the command line with the suffix %PVS, as a per-
centage of the remaining free space in the Volume Group with the suffix %FREE, or (for a snapshot) as a percentage of the total
space in the Origin Logical Volume with the suffix %ORIGIN. The resulting value is rounded downward for the substraction otherwise
it is rounded upward.
-L, --size [+|-]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
Change or set the logical volume size in units of megabytes. A size suffix of M for megabytes, G for gigabytes, T for terabytes, P
for petabytes or E for exabytes is optional. With the + or - sign the value is added or subtracted from the actual size of the log-
ical volume and rounded to the full extent size and without it, the value is taken as an absolute one.
-i, --stripes Stripes
Gives the number of stripes to use when extending a Logical Volume. Defaults to whatever the last segment of the Logical Volume
uses. Not applicable to LVs using the original metadata LVM format, which must use a single value throughout.
-I, --stripesize StripeSize
Gives the number of kilobytes for the granularity of the stripes. Defaults to whatever the last segment of the Logical Volume uses.
Not applicable to LVs using the original metadata LVM format, which must use a single value throughout.
StripeSize must be 2^n (n = 2 to 9).
--noudevsync
Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible
udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre-
ates.
EXAMPLES
Extend a logical volume vg1/lv1 by 16MB using physical extents /dev/sda:0-1 and /dev/sdb:0-1 for allocation of extents:
lvresize -L+16M vg1/lv1 /dev/sda:0-1 /dev/sdb:0-1
