Creating a Volume on Specific Disks

Example of Using Concatenated Disk Space to Create a Mirrored-Stripe Volume

Other storage specification classes for controllers, enclosures, targets and trays can be

used with ordered allocation. For example, the following command creates a 3-column

mirrored-stripe volume between specified controllers:

# vxassist -b -g mydg -o ordered make mirstr2vol 80g \

layout=mirror-stripe ncol=3 \

ctlr:c1 ctlr:c2 ctlr:c3 ctlr:c4 ctlr:c5 ctlr:c6

This command allocates space for column 1 from disks on controllers c1, for column 2

from disks on controller c2, and so on as illustrated in “Example of Storage Allocation

Used to Create a Mirrored-Stripe Volume Across Controllers” on page 208.
