Creating Volumes

Mirroring across Targets, Controllers or Enclosures

Chapter 7 251

# vxassist -b make volspec 10g layout=mirror nmirror=2

mirror=enclr enclr:enc1 enclr:enc2

The disks in one data plex are all taken from enclosure enc1, and the

disks in the other data plex are all taken from enclosure enc2. This

arrangement ensures continued availability of the volume should either

enclosure become unavailable.

See “Specifying Ordered Allocation of Storage to Volumes” on page 237

for a description of other ways in which you can control how volumes are

laid out on the speciﬁed storage.
