Installation guide

The volsetup utility creates the /etc/vol/volboot file. This file is used
to locate copies of the rootdg disk group configuration when the system
starts up.
_______________________ Note _______________________
Do not delete or manually update the /etc/vol/volboot file;
it is critical for starting LSM.
8.6.3 Adding a Disk to a Disk Group
Once LSM has been initialized with the /sbin/volsetup utility, you can
add more physical disks or disk partitions to the rootdg disk group or add
a new disk group by executing the interactive voldiskadd utility. This
utility requires that a disklabel already exist on the device. Refer to the
disklabel
(8) reference page for complete information. For example, you
could add a disk partition to the rootdg disk group by executing the
following command:
# voldiskadd rz3
To initialize a disk without adding it to a disk group, use the
voldisksetup
(8) command. This command allows you to add an LSM
simple disk or sliced disk.
To add a physical disk to LSM with a specific private region size, use the
voldisksetup
(8) command. For example, use the following command to
initialize a sliced LSM disk with a private region size of 2048 sectors:
# voldisksetup -i rz3 privlen=2048
Use the voldg command to add the LSM disk to a disk group.
8.6.4 Creating a Volume in a Disk Group
After you create a disk group and add disks, use the volassist command
to create volumes. For example:
# volassist -g disk_group make volume length attribute=value
To create a volume in a disk group, use the instructions in the following
list, or use the dxlsm graphical user interface (GUI).
• To use nonreserved disks to create a 10 MB volume in the rootdg disk
group, enter the following command:
# volassist -g rootdg make vol01 10m
