Question VXVM 3.5 Rootdg corrupt/recovery
Hi Everyone!

Would someone please tell me if it is still true that rootdg should not be used for production/primary data and that you should create additional disk groups so that if rootdg gets corrupt you can recreate rootdg and then bring in the other groups with no data loss. Or is it still true that if you use rootdg for production data then you will have to restore it once you recreate your rootdg.

A coworker mentioned that we no longer have to worry about rootdg in 3.5 because VXVM can be brought up without it. I went to class but they didn't mention this..?

VXVM 4.0, I know, does not require rootdg. VM3.5, I know, still requires rootdg but how is it handle in the case of a corruption/recovery?


I appreciate any comments !!

vxinstall

vxinstall(1M)															     vxinstall(1M)

NAME

       vxinstall - menu-driven Veritas Volume Manager initial configuration procedure

SYNOPSIS

       vxinstall

DESCRIPTION

       The  vxinstall utility provides a menu driven interface to configure Veritas Volume Manager (VxVM).  If you install the Veritas Volume Man-
       ager software package using the operating system's package administration commands, you can run vxinstall to configure VxVM for initial use
       on your system.

       Note: If you use the Veritas software installation scripts, do not run this utility.

OPERATIONS

       Licensing
	    vxinstall  first asks if you want to view the Veritas licenses already installed on the system.  Answering "yes" is equivalent to exe-
	    cuting the vxlicrep command (see vxlicrep(1)).

	    You are then asked if you want to add licenses for other Veritas products.	Answering "yes" is equivalent  to  running  the  vxlicinst
	    command (see vxlicinst(1)).  and entering a license key.

       Enclosure-Based Naming
	    You  can choose whether you want to use disk access names that are based on the device names assigned by the operating system, or that
	    are based on names that you assign to enclosures.

       System-Wide Default Disk Group
	    You can enter the name for the default disk group (defaultdg).  This is an alias for the disk group name that should be assumed if the
	    -g	option is not specified to a command, or if the VXVM_DEFAULTDG environment variable is undefined.  By default, defaultdg is set to
	    nodg (that is, no disk group).

NOTES

       From release 4.0 of VxVM, it is no longer necessary to run vxinstall to configure the rootdg disk group.  Disks	and  disk  groups  may	be
       added  to  VxVM	by  running  commands such as vxdiskadm(1M) or by using the graphical user interface without first running vxinstall.  The
       operation of VxVM does not require any disk groups to have been configured, and a disk group named rootdg does not need to  be  present	on
       the system.  Any disk group may be configured as the default disk group that is to be used with VxVM commands.  Any disk group named rootdg
       has no special significance to VxVM. See the vxdg(1M) manual page for further details.
