# lsvg -l prodvg
prodvg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
loglv00 jfs2log 1 1 1 open/syncd N/A
apps_lv jfs2 1600 1600 4 open/syncd /apps
3g_lv jfs2 480 480 2 open/syncd /prod/3g
db_lv jfs2 2560 2560 7 open/syncd /prod/db
logs_lv jfs2 240 240 1 open/syncd /prod/logs

inst_lv jfs2 720 720 2 open/syncd /prod/inst

Not sure why you want to have your system offline to do a mksysb, but just run one online to see how long it takes.
