In this posting, we will learn how to create Filesystem on IBM AIX. If we have a cluster system, then we need to create the same filesystem definition in all servers that used in cluster system. For this reason, we only exportvg in a server and import it to another servers.
0. Scan your new LUN/Disk
# cfgmgr -v
1. List up Available PV (Phisycal Volume)
# lspv hdisk0 00c3a6b534737131 rootvg active hdisk1 00c3a6b5bf30a665 rootvg active hdisk2 00c3a6b5c2bc7f66 vg01 active hdisk22 none None
2. Create VG (Volume Group, -S Scalable, -f Force, -y VGName)
# mkvg -S -f -y vg19 hdisk22
3. Assure the VG size
# lsvg vg19 VOLUME GROUP: vg19 VG IDENTIFIER: 00c3a7a500004c000000012 VG STATE: active PP SIZE: 32 megabyte(s) VG PERMISSION: read/write TOTAL PPs: 1117 (35744 megabytes) MAX LVs: 256 FREE PPs: 1117 (35744 megabytes) LVs: 0 USED PPs: 0 (0 megabytes) OPEN LVs: 0 QUORUM: 2 (Enabled) TOTAL PVs: 1 VG DESCRIPTORS: 2 STALE PVs: 0 STALE PPs: 0 ACTIVE PVs: 1 AUTO ON: yes MAX PPs per VG: 32768 MAX PVs: 1024 LTG size (Dynamic): 256 kilobyte(s) AUTO SYNC: no HOT SPARE: no BB POLICY: relocatable
4. Create Log LV (filesystem type jfs2 need loglv for journaling)
# mklv -y loglv19 -t jfs2log vg19 1
5. Create LV (Create Logical Volume with filesystem type jfs2)
# mklv -y lv19 -t jfs2 vg19 35000M
OR using FREE PP – 1
# mklv -y lv19 -t jfs2 vg19 1116
6. Create FileSystem
# crfs -v jfs2 -d /dev/lv19 -a log=/dev/loglv19 -m /u01/apps
7. Mounting Filesystem
# mount /dev/lv19
To Check the filesystem already mounted or not :
# df -g
Import VG to Destination server :
1. Umount File system on source server:
# umount /dev/lv19
2. Deactivate VG on source server
# varyoffvg vg19
3. Activate VG and unlock it on source server:
# varyonvg -b -u vg19
4. Check Phisical name in destination server, if phisycal name as same as source server we can used Phisycal name
otherwise if physical name in source server different with destination server, we can used path address.
# lspv hdisk22 00c3a81592bdbb4e vg19 active
5. Import VG on destination server:
# importvg -y vg19 hdisk22
OR
# importvg -y vg19 00c3a81592bdbb4e
6. All definition of VG19 already add on destination server. We can mounted it in destination server,
but before we mount, we should deactivate vg on source server.
In Source server :
# varyoffvg vg19
In Destination server :
# mount /dev/lv19
Done, now you can mounting the filesystem in source system and target system alternately.
