Use the HDLM device (slice) to create a local metadevice (logical disk).
The types of metadevices include coupled, stripe, mirrored, RAID5, and
transmeta devices.
The following shows an example of executing the command to create local
metadevice (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 metadevice.
.
The following shows an example of executing the command:
host1# newfs /dev/md/rdsk/d0

The following shows an example of executing the command:
host1# mkdir -p /mnt/filesystem1
host1# mount /dev/md/dsk/d0 /mnt/filesystem1

To Use a Shared Diskset

For disks registered with the SDS shared diskset, SDS automatically allocates
the minimal number of state databases that store the configuration and
status of shared metadevices 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, the existing partitions
may be reconfigured. For details, refer to the SDS documentation.
To use a shared diskset:
1 Create three replicas of the local state database on the disk (slice).
.
Create these replicas on all hosts that use the shared diskset. Make sure
that all the following conditions are satisfied for the creation-target disk:
