8.2.2 LSM Disks

You must add physical disks to the LSM environment as LSM disks before

you can use them to create LSM volumes. Refer to Section 8.6.3 and the

voldiskadd

(8) reference page for information about adding physical disks

to LSM.

An LSM disk typically uses the following two regions on each physical disk:

• A small region, called the private region, in which LSM keeps its disk

media label and a conﬁguration database

• A large region, called the public region, that forms the storage space for

building subdisks
