Solstice DiskSuite 4.2.1 Reference Guide

Creating a Concatenated Metadevice in the md.tab File

This example shows a metadevice, /dev/md/dsk/d7, that has a four-slice concatenated metadevice.

# (concatenation of four disks)
d7 4 1 c0t1d0s0 1 c0t2d0s0 1 c0t3d0s0 1 c0t4d0s0

The number 4 specifies to create four striped slices in the concatenated metadevice. Each stripe is made of one slice; therefore, you specify the number 1 for each slice.

Note -

The first disk sector in the concatenated metadevice contains a disk label. To preserve the disk labels on devices /dev/dsk/c0t2d0s0, /dev/dsk/c0t3d0s0, and /dev/dsk/c0t4d0s0,DiskSuite skips the entire first cylinder of these disks. This permits higher-level file system software to optimize block allocations correctly.
