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.
Creating File Systems
If your installation uses filesystems, create them next. Use the following
commands to create a filesystem for mounting on the logical volume just
created:
1. Create the filesystem on the newly created volume:
# newfs -F vxfs /dev/vx/rdsk/logdata/log_files
2. Create a directory to mount the volume:
