scdidadm Exits With an Error if /dev/rmt is Missing (4783135)

Problem Summary: The current implementation of scdidadm(1M) relies on the existence of both /dev/rmt and /dev/(r)dsk to successfully execute scdiadm -r. Solaris installs both, regardless of the existence of the actual underlying storage devices. If /dev/rmt is missing, scdidadm exits with the following error:

Cannot walk /dev/rmt" during execution of 'scdidadm -r

Workaround: On any node where /dev/rmt is missing, use mkdir to create a directory /dev/rmt. Then, run scgdevs from one node.
