To Create a RAID 1 (Mirror) Volume with the metassist command

Steps

1. Make sure that you have the necessary prerequisites for using top down volume creation (the metassist command).

2. Identify available storage on which to create the mirror.

   If you do not explicitly specify any storage, Solaris Volume Manager will identify unused storage on the system and use it as appropriate. If you choose to specify storage, either broadly (for example, all storage on controller 1) or specifically (for example, use c1t4d2, but do not use c1t4d1), Solaris Volume Manager will use the storage you specify as needed.

3. Use the following form of the metassist command to create a two–way mirror:

   metassist create-s diskset-name-r redundancy -S size

   • create is the subcommand to create volumes.

   • -s diskset-name specifies the name of the disk set to use for the volumes.

   • -r redundancy specifies the level of redundancy (number of data copies) to create.

   • -S size specifies the size of the volume to create in KB, MB, GB, or TB, for kilobytes, megabytes, gigabytes, and terabytes, respectively.

   See the following examples and the metassist(1M) man page for more information.

4. Use the metastat command to view the new volumes (two striped submirrors and one mirror).

   metastat -s diskset-name
