3.14.2 Registering HDLM Devices
If both HDLM and SDS are used on the same host, perform the following settings after
installing HDLM.
(1) To Use a Local Metadevice
To use a local metadevice:
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 metadevice.
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
4. Mount the created file system to the mount point.
The following shows an example of executing the command:
host1# mkdir -p /mnt/filesystem1
host1# mount /dev/md/dsk/d0 /mnt/filesystem1
(2) 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
