Creating Disk Groups
Use vxdiskadm, or use the vxdg command, to create disk groups, as in
the following example:
vxdg init logdata c0t3d2
Verify the configuration with the following command:
vxdg list
NAME STATE ID
rootdg enabled 971995699.1025.node1
logdata enabled 972078742.1084.node1
Creating Volumes
Use the vxassist command to create logical volumes. The following is
an example:
vxassist -g logdata make log_files 1024m
This command creates a 1024 MB volume named log_files in a disk
group named logdata. The volume can be referenced with the block
device file /dev/vx/dsk/logdata/log_files or the raw (character)
device file /dev/vx/rdsk/logdata/log_files. Verify the configuration
with the following command:
vxprint -g logdata
The output of this command is shown in the following example:
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE
TUTILO PUTILO
v logdata fsgen ENABLED 1024000 ACTIVE
pl logdata-01 system ENABLED 1024000 ACTIVE
NOTE The specific commands for creating mirrored and multi-path storage
using VxVM are described in the Veritas Volume Manager Reference
Guide.
