AIX change device

AIX:
Available -> defined
rmdev -l ovpass0
defined -> available
mkdev -l smc0

Steps to increase SAN storage for AIX

umount /filesystem
varyoffvg vgname
chvg -g vgname
varyonvg vgname
mount /filesystem

then
LVM > LV > FS

Check info of LPAR

HP-UX: Disk and Filesystem tasks

Search for attached disk:
ioscan -fnC disk

Initialize a disk for use with LVM:
pvcreate -f /dev/rdsk/c0t1d0

Create the device structure needed for a new volume group:
cd /dev
mkdir vgdata
cd vgdata
mknod group c 64 0x010000

Create volume group vgdata:
vgcreate vgdata /dev/dsk/c0t1d0
{ if your expecting to use more than 16 physical disks use the -p option, range from 1 to 256 disks. }

Display volume group vgdata:
vgdisplay -v vg01

Add another disk to volume group:
pvcreate -f /dev/rdsk/c0t4d0
vgextend vg01 /dev/dsk/c0t4d0

Remove disk from volume group:
vgreduce vg01 /dev/dsk/c0t4d0

Create a 100 MB logical volume lvdata:
lvcreate -L 100 -n lvdata vgdata
newfs -F vxfs /dev/vgdata/rlvdata

Extend logical volume to 200 MB:
lvextend -L 200 /dev/vgdata/lvdata

Extend file system to 200 MB:
{ if you don't have Online JFS installed volumes must be unmounted before you can extend the file system. }
fuser -ku /dev/vgdata/lvdata { kill all process that has open files on this volume. }
umount /dev/vgdata/lvdata
extendfs /data
{ for Online JFS, 200 MB / 4 MB = 50 LE; 50 x 1024 = 51200 blocks }
fsadm -F vxfs -b 51200 /data

Set largefiles to support files greater than 2GB:
fsadm -F vxfs -o largefiles /data


Exporting and Importing disks across system:
1. make the volume group unavailable
vgchange -a n /dev/vgdata
2. Export the the disk while creating a logical volume map file.
vgexport -v -m data_map vgdata
3. Disconnect the drives and move to new system.
4. Move the data_map file to the new system.
5. On the new system recreate the volume group directory
mkdir /dev/vgdata
mknod /dev/vgdata/group c 64 0x02000
6. Import the disks to the new system
vgimport -v -m data_map /dev/vgdata /dev/dsk/c2t1d0 /dev/dsk/c2t2d0
7. Enable the new volume group
vgchange -a y /dev/vgdata

Renaming a logical volume:
/dev/vgdata/lvol1 -> /dev/vgdata/data_lv
umount /dev/vgdata/lvol1
ll /dev/vgdata/lvol1 take note of the minor ( e.g 0x010001 )
brw-r----- 1 root root 64 0x010001 Dec 31 17:59 lvol1
mknod /dev/vgdata/data_lv b 64 0x010001 create new logical volume name
mknod /dev/vgdata/rdata_lv c 64 0x010001
vi /etc/fstab { reflect the new logical volume }
mount -a
rmsf /dev/vgdata/lvol1
rmsf /dev/vgdata/rlvol1
