vxdctl – UnixArena’s Manual Page

Product – Veritas Volume Manager 6.0 (Storage Foundation)

/usr/sbin/vxdctl

  •  Manages aspects of the state of the volume configuration daemon ‘vxconfigd’.
  •  Sets default disk group for the system.
  •  Sets Boot Disk Group if the root disk is under VxVM Control.
  •  It uses ‘/etc/volboot’ file to manage default & boot disk groups. It also uses the host ID to establish ownership of physical disks.

vxdctl  – Examples

Set Default Boot Diskgroup

  # vxdctl bootdg rootdg

Set Default Diskgroup

  # vxdctl defaultdg testdg

Enable or disable command completion

  # vxdctl cmdcompletion enable
	  VxVM vxdctl INFO V-5-2-0
	  Enabling command auto-completion feature with this interface will: 
	    - Newly create .bash_profile, if it is not present.
	    - If .profile file exists, it will copy the contents of .profile to .bash_profile.
	        So user need to use .bash_profile as a default profile file.
	    - Persistently enable the feature with every login to bash shell.

	  If you don't wish to newly create .bash_profile, then you need to either reinvoke
	    bash shell or source /etc/bash_completion.d/vx_bash manually each time you login.

	  Do you want to continue? [y,n,q,?]  (default: y) y
 	 VxVM vxdctl INFO V-5-2-0  VxVM command auto-completion successfully enabled.

   # vxdctl cmdcompletion disable
  	VxVM vxdctl INFO V-5-2-0   VxVM command auto-completion successfully disabled.

Place ‘vxconfigd’ into ‘disabled’ mode for maintenance operations

  # vxdctl disable

  	# vxprint -hvtg oradg
	VxVM vxprint ERROR V-5-1-684 IPC failure: Configuration daemon is not accessible

Enable ‘vxconfigd’ to rebuild device node directories & DMP databases

  # vxdctl enable

Change the ‘hostid’ in volboot file

  # vxdctl hostid s10u11.vxtestserver
