Series 500 Only

NAME

rootmark − mark/unmark volume as HP-UX root volume

SYNOPSIS

/etc/rootmark [ −m | −u ] filespec

Remarks:

Rootmark is implemented on the Series 500 only. 

DESCRIPTION

Rootmark enables you to control which mass storage device contains your HP-UX root (/) directory.  The HP-UX operating system searches mass storage devices and uses the first root volume it finds. 

Filespec is usually a character special file which points to a mass storage volume initialized with Structured Directory Format (SDF).  If invoked with no option, rootmark tells the current state of the specified volume.  If −m is specified, then the specified volume is marked as a root volume.  If −u is specified, the specified volume is marked as not a root volume.  Rootmark is silent if successful. 

RETURN VALUE

Rootmark sends an error message to standard error and returns a non-zero value if it cannot read or write a volume, or if a volume is not SDF.  Rootmark returns 1 for incorrect syntax, 2 for a file system problem, and 3 for a volume that is not in SDF. 

EXAMPLE

The following example makes /dev/rhd usable as root; you must super-user to execute the example:

# rootmark /dev/rhd     # check if /dev/rhd is a root volume
/dev/rhd is marked as NOT a root volume.
# rootmark -m /dev/rhd  # mart it as the root volume
# rootmark /dev/rhd     # check results
/dev/rhd is marked as a root volume.

SEE ALSO

mount(1), osmgr(1M), sdfinit(1M). 

WARNINGS

A volume must not be marked as a root volume unless it contains all the directories and files that HP-UX requires for system initialization. 

Never mark any media shipped from Hewlett-Packard as not a root volume, in case you need to re-install HP-UX from that media.
