[AIX] How to increase the size of a logical volume?
You can To Increases the size of a logical volume by adding unallocated physical partitions from within the volume group. Here is an example to increase the size of the logical volume represented by the testlv01by eight logical partitions,
1). Run lslv to show detail information of testlv01
# lslv testlv01
LOGICAL VOLUME: testlv01 VOLUME GROUP: test_vg01
LV IDENTIFIER: 0009270e00004c000000011daff617f9.5 PERMISSION: read/write
VG STATE: active/complete LV STATE: closed/syncd
TYPE: jfs WRITE VERIFY: off
MAX LPs: 512 PP SIZE: 4 megabyte(s)
COPIES: 1 SCHED POLICY: parallel
LPs: 16 PPs: 16
STALE PPs: 0 BB POLICY: relocatable
INTER-POLICY: minimum RELOCATABLE: yes
INTRA-POLICY: middle UPPER BOUND: 32
MOUNT POINT: N/A LABEL: None
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes
Serialize IO ?: NO
2). Extend the size of the logical volume by eight logical partitions:
# extendlv testlv01 8
3). Validate the changes made on testlv01:
# lslv testlv01
LOGICAL VOLUME: testlv01 VOLUME GROUP: test_vg01
LV IDENTIFIER: 0009270e00004c000000011daff617f9.5 PERMISSION: read/write
VG STATE: active/complete LV STATE: closed/syncd
TYPE: jfs WRITE VERIFY: off
MAX LPs: 512 PP SIZE: 4 megabyte(s)
COPIES: 1 SCHED POLICY: parallel
LPs: 24 PPs: 24
STALE PPs: 0 BB POLICY: relocatable
INTER-POLICY: minimum RELOCATABLE: yes
INTRA-POLICY: middle UPPER BOUND: 32
MOUNT POINT: N/A LABEL: None
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes
Serialize IO ?: NO
