Registering HDLM Devices

If SVM is used, perform the following settings after installing HDLM, and
register the SVM volume.

To Use a Local Volume

To use a local volume:
1 Create a replica of the state database.
.
Create three replicas of the local state database on the disk (slice).
Create these replicas on a disk that is not managed by HDLM, not shared,
and has not been connected to a Fibre Channel.
The following shows an example of executing the command:
host1# metadb -a -f c1t1d0s1 c1t1d0s3 c1t1d0s7
2 Create a local volume.
.
Use the HDLM device (slice) to create a local volume (logical disk).
The types of volumes include coupled, stripe, mirrored, and RAID5.
The following shows an example of executing the command to create a
local volume (d0) of type stripe (1) comprised of two HDLM devices
(slices).
host1# metainit d0 1 2 c5t1d0s7 c5t2d1s7
3 Create a file system on the local volume.
.
The following shows an example of executing the command:
host1# newfs /dev/md/rdsk/d0
4 Mount the created file system to the mount point.
.
The following shows an example of executing the commands:
host1# mkdir -p /mnt/filesystem1
host1# mount /dev/md/dsk/d0 /mnt/filesystem1

To Use a Shared Diskset

For disks registered with the shared diskset, SVM automatically allocates the
minimal number of state databases that store the configuration and status of
shared volumes created on a shared diskset. When using Sun Cluster, you
use the device ID in the device name of the disk.
Note
When you register a disk into a shared diskset, existing partitions may be
reconfigured. For detail, refer to the SVM documentation.
To use a shared diskset:
1 Create three replicas of the local state database on the disk (slice).
