Hi,

If your talking about swap space, that's fairly simple, in fact it is recommended.

If your not using an existing volume group, you need to create one. Make sure that you using the right disk.

# pvcreate /dev/rdsk/cxytdz (change to your disk)
# vgcreate /dev/vg01 /dev/dsk/cxtydz
# lvcreate -n swaplv2 /dev/vg01
# lvextend -L 2048 /dev/vg01/swaplv (change to your size)
# swapon /dev/vg01/swaplv2

Of course all of this can be done via 'sam'

Some more hints for you, in case you encounter problem in enlarging the swap space, you might probably need to increase the kernel parameters "maxswapchunks", the figures reflect the max no. of blocks for swap space, the default may not be good enough for your extended setting.
