LDOMs: Powering off the primary domain

To power-off your primary domain (LDOM platform) you will need to use < # init 0 > followed by a power off from the console. An < # init 5 > will behave as an < # init 6 > if you have LDOMs configured.

 

Problems with < format > hanging, enter this at the cli and then run format again

# NOINUSE_CHECK=1; export NOINUSE_CHECK

 

Format new root disk with same vtoc as rootmirror disk.

# prtvtoc /dev/dsk/”root-mirror” > /tmp/root-mirror.txt

# fmthard -s /tmp/root-mirror.txt /dev/dsk/”root-disk”

 

Add a disk to a running Non-Global Zone (NGZ) from Global Zone (GZ) without a reboot

# mount -F lofs /<GZ mountpoint> /<NGZ mountpoint>

 

Display static routes created at bootup

# route -p show

# route get default
