scgdevs(1M) System Administration Commands scgdevs(1M)
NAME
scgdevs - global devices namespace administration script
SYNOPSIS
/usr/cluster/bin/scgdevs
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
The scgdevs command manages the global devices namespace. The global devices namespace is mounted under the /global directory and consists
of a set of logical links to physical devices. As the /dev/global directory is visible to each node of the cluster, each physical device is
visible across the cluster. This fact means that any disk, tape, or CD-ROM that is added to the global-devices namespace can be accessed
from any node in the cluster.
The scgdevs command enables you to attach new global devices (for example, tape drives, CD-ROM drives, and disk drives) to the global-
devices namespace without requiring a system reboot. You must run the devfsadm command before you run the scgdevs command.
Alternatively, you can perform a reconfiguration reboot to rebuild the global namespace and attach new global devices. See the boot(1M) man
page for more information about reconfiguration reboots.
You must run this command from a node that is a current cluster member. If you run this command from a node that is not a cluster member,
the command exits with an error code and leaves the system state unchanged.
You can use this command only in the global zone.
You need solaris.cluster.system.modify RBAC authorization to use this command. See the rbac(5) man page.
You must also be able to assume a role to which the Sun Cluster Commands rights profile has been assigned to use this command. Authorized
users can issue privileged Sun Cluster commands on the command line from the pfsh, pfcsh, or pfksh profile shell. A profile shell is a spe-
cial kind of shell that enables you to access privileged Sun Cluster commands that are assigned to the Sun Cluster Commands rights profile.
A profile shell is launched when you run the su command to assume a role. You can also use the pfexec command to issue privileged Sun Clus-
ter commands.
EXIT STATUS
The following exit values are returned:
0 The command completed successfully.
nonzero An error occurred. Error messages are displayed on the standard output.
FILES
/devices Device nodes directory
/global/.devices Global devices nodes directory
/dev/md/shared Solaris Volume Manager metaset directory

NOTES
The scgdevs command, called from the local node, will perform its work on remote nodes asynchronously. Therefore, command completion on the
local node does not necessarily mean that the command has completed its work clusterwide.
This document does not constitute an API. The /global/.devices directory and the /devices directory might not exist or might have different
contents or interpretations in a future release. The existence of this notice does not imply that any other documentation that lacks this
notice constitutes an API. This interface should be considered an unstable interface.
