Using smitty lvm I created a new logical volume called fslv07:
HTML Code:
LOGICAL VOLUME: fslv07 VOLUME GROUP: vg01
LV IDENTIFIER: 000a8dac00004c00000000fc5ae7fa77.15 PERMISSION: read/write
VG STATE: active/complete LV STATE: closed/syncd
TYPE: jfs2 WRITE VERIFY: on
MAX LPs: 512 PP SIZE: 128 megabyte(s)
COPIES: 1 SCHED POLICY: parallel
LPs: 12 PPs: 12
STALE PPs: 0 BB POLICY: relocatable
INTER-POLICY: minimum RELOCATABLE: yes
INTRA-POLICY: middle UPPER BOUND: 1
MOUNT POINT: N/A LABEL: /0racle11g
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes
Serialize IO ?: YES
I believe that I need to create a mount point to it now using smitty fs. What determines what size this filesystem is? I need around 15 to 20GB.
Thank you.

Hello all,
I'm sharing 1 volume from a Sun Storage array (6130), out to 2 servers. Created a slice on one server and mounted a filesystem. On the other server the disk already sees the created slice from the other server (shared throught the storage array, so mounted this filesystem as well.

Dear Gurus,
Could it be possible to have the output of df -k sorted? The df -k output messed up after recent power trip.
Also, is there any folders that I should look into to reduce the root size (other than /var/adm and /var/crash) after server crash?
Many thanks in advance.

lvreduce
LVREDUCE(8) System Manager's Manual LVREDUCE(8)
NAME
lvreduce - reduce the size of a logical volume
SYNOPSIS
lvreduce [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] {-l|--extents [-]LogicalExtentsNumber[%{VG|LV|FREE}] | -L|--size
[-]LogicalVolumeSize[kKmMgGtT]} [-t|--test] [-v|--verbose] LogicalVolume[Path]
DESCRIPTION
lvreduce allows you to reduce the size of 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 resized before running lvreduce so that the extents that are to be removed
are not in use.
Shrinking snapshot logical volumes (see lvcreate(8) for information to create snapshots) is supported as well. But to change the number of
copies in a mirrored logical volume use lvconvert (8).
Sizes will be rounded if necessary - for example, the volume size must be an exact number of extents and the size of a striped segment must
be a multiple of the number of stripes.
OPTIONS
See lvm for common options.
-f, --force
Force size reduction without any question.
-l, --extents [-]LogicalExtentsNumber[%{VG|LV|FREE}]
Reduce or set the logical volume size in units of logical extents. With the - sign the value will be subtracted from the logical
volume's actual size and without it the will be taken as an absolute size. The number can also be expressed as a percentage of the
total space in the Volume Group with the suffix %VG or relative to the existing size of the Logical Volume with the suffix %LV or as
a percentage of the remaining free space in the Volume Group with the suffix %FREE.
-L, --size [-]LogicalVolumeSize[kKmMgGtTpPeE]
Reduce or set the logical volume size in units of megabyte by default. A size suffix of k for kilobyte, m for megabyte, g for giga-
bytes, t for terabytes, p for petabytes or e for exabytes is optional. With the - sign the value will be subtracted from the logi-
cal volume's actual size and without it it will be taken as an absolute size.
Example
"lvreduce -l -3 vg00/lvol1" reduces the size of logical volume lvol1 in volume group vg00 by 3 logical extents.
