Nomadic Disk Manager Configuration Statements
Example
The following is an example of fully configured paths for a segment. A segment must
have at least one path specified, or else a subsequent ADD SEGMENT command is
not allowed.
SET PATH P $SM01.#A 1 STRAIGHT
SET PATH B $SM01.#A 2 STRAIGHT
SET PATH M $SM02.#A 1 CROSSED
SET PATH MB $SM02.#A 2 CROSSED
SET VOL Statement
The SET VOL statement modifies the segment template to be used by a subsequent
ADD SEGMENT statement. The SET VOL statement adds a disk volume to a
segment. Each segment definition can have from 1 to 16 SET VOL statements for
segments containing internal 46xx disk drives or 1 to 64 SET VOL statements for
segments containing external 45xx disk drives.
name
specifies the name of a disk volume. This device must exist.
$ldev
specifies the logical device number of a disk volume.
On NonStop K-series servers, $ldev allows you to specify the disk volume if it
was configured as a demountable device. Demountable devices do not exist on
NonStop S-series servers.
$alt-name
specifies a syntactically valid device name that matches the name of the device
designated by $
ldev .
SET VOL { $name }
{ $ldev [ ( $alt-name ) ] }
Caution. Do not use the $ldev parameter. On NonStop S-series servers, logical device
numbers are arbitrarily assigned to a device when you configure the device and every time the
system is loaded.
