Veritas 4.1 Installation Guide (HP-UX 11i v3, February 2007)

Use the vxnotify command as follows:
vxnotify [-ACcdefimr] -g <diskgroup> -n <number> -t <timeout> -w
<wait-time>
See vxnotify (1M), for more information on the supported options.
• Removing Disks From Disk Group
Remove disks from Disk Group:
# vxdg -g <diskgroup> rmdisk <diskname>
See vxdg (1M), for more information on the supported options.
Subdisks
Subdisks are low-level building blocks in a Veritas Volume Mananger (VxVM) configuration
that are required to create plexes and volumes.
You can do the following operations on subdisks:
• Creating Subdisks
Create a subdisk:
# vxmake -g <diskgroup> sd <subdisk> <diskname>,<offset>,<length>
See vxmake (1M), for more information on the supported options.
• Displaying subdisk information
The vxprint command displays information about VxVM objects.
— Display information on all subdisks:
# vxprint -st
See vxprint (1M), for more information on the supported options.
— Display information on a specific subdisk:
# vxprint -g <diskgroup> -l <subdisk>
See vxprint (1M), for more information on the supported options.
• Moving Subdisks
Moving a subdisk copies the disk space contents of a subdisk onto one or more subdisks.
Move a subdisk:
# vxsd -g <diskgroup> mv <old_subdisk> <new_subdisk [new_subdisk ...]>
See vxsd (1M), for more information on the supported options.
NOTE: For the subdisk move to work correctly, the following conditions must be satisfied:
— The subdisks involved must be the same size.
— The subdisk being moved must be part of an active plex on an active (ENABLED)
volume.
— The new subdisk must not be associated with any other plex.
• Splitting Subdisks
Splitting a subdisk divides an existing subdisk into two separate subdisks.
Split a subdisk:
# vxsd -g <diskgroup> –s <size> split <subdisk> <newsd1> <newsd2>
See vxsd (1M), for more information on the supported options.
• Joining Subdisks
Joining subdisks combines two or more existing subdisks into one subdisk. To join subdisks,
the subdisks must be contiguous on the same disk.
