Verifying That Plexing Is Supported

Verifying That Plexing Is Supported

As discussed in Chapter 7, "Creating and Administering XLV Logical Volumes," the plexing feature of XLV, which enables the use of multiple plexes, is available only when you purchase the Disk Plexing Option software option. It requires a NetLS license which must be installed in a nonstandard location, /etc/nodelock.

You can use the xlv_mgr command to verify that the plexing software and a valid license are installed. Follow these steps:

Invoke xlv_mgr:
# xlv_mgr
Give the show config command:
xlv_mgr> show config
Allocated subvol locks: 30 locks in use: 6
Plexing license: present
Plexing support: present
Maximum subvol block number: 0x7fffffffffffffff
The third line of output, "Plexing support is present," indicates that plexing software is installed with a valid license.
Quit out of xlv_mgr:
xlv_mgr> quit
