hp-ux : Verify the status of the link aggregate

Determine which lans to configure

Link Speeds and Duplex settings should be the same.
ioscan -fnkC lan       ## to determine available lans
each lan used in the aggregate must be disabled before starting APA.
# ifconfig lan(n) down
# ifconfig lan(n) unplumb

To stop/start the new configuration  (APA doesn’t require a reboot to take effect)

/sbin/init.d/hpapa stop
/sbin/init.d/hpapa start

Assign an ipaddress to lan900.

# ifconfig lan900 ipaddress netmask netmaskaddress
# ifconfig lan900                 # # to check
# modify /etc/rc.config.d/netconf      ##to make the ipaddress permanent

Verify the status of the link aggregate

* lanadmin -x -v 900           ## will show the number of ports, state, mode
* lanscan -v                              ## verify which link aggregates have been configured.
* lanadmin –x –p 2 900      ## verify the status of a particular port

Search for attached disk
ioscan -fnC disk
---
Create special file
insf -Cdisk
---
Initialize a disk for use with LVM
pvcreate -f /dev/rdsk/c0t1d0       #"-f" option only when absolutely needed.
---
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
--- OR
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 )
