Changing the Disk-Naming Scheme
61
You can exclude all disks on specific controllers from initialization by listing those
controllersin the file/etc/vx/cntrls.exclude. The followingis an exampleofan
entry in a cntrls.exclude file:
c0
You can exclude all disks in specific enclosures from initialization by listing those
enclosures in the file /etc/vx/enclr.exclude. The following is an example of an
entry in a enclr.exclude file:
enc1
Note Only the vxinstall and vxdiskadm commands use the contents of the
/etc/vx/disks.exclude, /etc/vx/cntrls.exclude and
/etc/vx/enclr.exclude files. You may need to create these files if they do not
already exist on the system.
Changing the Disk-Naming Scheme
You can either use enclosure-based naming for disks or the traditional naming scheme
(such as c#t#d#). Select menu item 20 from the vxdiskadm main menu to change the
disk-naming scheme that you want VxVM to use. Selecting this option displays the
following screen:
Change the disk naming scheme
Menu: VolumeManager/Disk/NamingScheme
Use this screen to change the disk naming scheme (from the c#t#d#
format to the enclosure based format and vice versa).
NOTE: This operation will result in vxconfigd being stopped and
restarted.
Volume Manager is currently using the enclosure based format to
name disks on the system.
Do you want to change the naming scheme ? [y,n,q,?] (default: n)
Enter y to change the naming scheme. This restarts the vxconfig daemon to bring the
new disk naming scheme into effect.
