NAME

scgdevs– global device namespace administration script

SYNOPSIS

/usr/cluster/bin/scgdevs

DESCRIPTION

The scgdevs utility manages the global devices namespace. The global devices namespace is mounted under /global and consists of a set of logical links to physical devices. As /dev/global is visible to each node of the cluster it follows that each physical device is visible across the cluster. This means that any disk, tape or CD ROM added to the global devices namespace can be accessed from any node in the cluster.

The scgdevs command allows the administrator to attach new global devices (for example, tape drives, CD-ROM drives and disk drives) to the global device namespace without requiring a system reboot. The drvconfig(1M) and devlinks(1M) commands must be executed prior to the script.

Alternatively, a reconfiguration reboot can be used to rebuild the global namespace and attach new global devices. See boot(1M).

This script must be run from a node that is a current cluster member. If it is run from a node that is not a cluster member, it exits with an error code and leaves the system state unchanged.

EXIT STATUS

The following exit values are returned:

0

Successful completion.

non-zero

An error occurred. Error messages are displayed on the standard output.
