- By using SAM
SAM > Disk and File Systems > Swap > Actions
You can add the Device Swap or File System Swap.
- By Command Line
Create the logical volume for your secondary swap:
# lvcreate -L 128 /dev/vg14
NOTE: “-L 128” is the size of desired swap
Verify the logical volume:
# lvdisplay /dev/vg14/lvol15
Use SAM to declare your new secondary swap or use the command line:
# swapon /dev/vg14/lvol15
Verify it has been added in “/etc/fstab” when using SAM, or add it manuallywhen using the command line.
/dev/vg14/lvol15 . swap defaults 0 0
To view a list of peripherals on the server, issue the command…
- For HDD
ioscan -nfC disk
- For tape drive
ioscan -nfC tape
- For LAN – Ethernet Card
ioscan -nfC LAN
- For FC – Fiber Channel
ioscan -nfC FC
The next time you want to view it again, you can use the -k option for cache so that you don’t have to wait for it to scan the entire system again.
ioscan -knfC disk
Before increasin the size of the logical volume, always ensure that you do a make_tape_recovery and fbackup on the data stored on that particular logical volume that you wish to increase.
Always check your current and free lvol size before increasing so you can keep track and notice the differents.
We take a scenario where I would want to increase my /dev/vg00/lvol10 to 1GB
- umount /dev/vg00/lvol10
- lvextend -L 1024 /dev/vg00/lvol10
- extendfs -F vxfs /dev/vg00/lvol10
- mount /dev/vg00/lvol10 /myfolder
bdf command to check your increased lvol size.
# On source host
/usr/lbin/sysadm/system_prep -s system

This free tool gives you a huge amount of information all on one screen. Even though IBM doesn’t officially support the tool and you must use it at your own risk, you can get a wealth of performance statistics. Why use five or six tools when one free tool can give you everything you need? NMON can be downloaded and explored from here.
This free tool is designed to take files produced by the NMON performance tool and turn them into spreadsheets containing high quality graphs ready to cut and paste into performance reports. The tool also produces analyses for ESS and FAStT subsystems. NMON Analyser can be downloaded and accessed from here.
