PATHMON Configuration File
You can use DEFINEs to specify names for the files that PATHCOM uses directly as
IN, OUT, and OBEY command files. In the following example, PATHCOM reads
commands from the command file specified by DEFINE =CMD-FILE
($DATA.PW.CONFIG) and lists them on the device specified by DEFINE =OUT-FILE
($S):
12> ADD DEFINE =CMD-FILE, CLASS MAP, FILE $DATA.PW.CONFIG
13> ADD DEFINE =OUT-FILE, CLASS SPOOL, LOC $S, REPORT
"CONFIG"
14> PATHCOM /IN =CMD-FILE, OUT =OUT-FILE/ $PM
For detailed information about DEFINEs in the Guardian operating environment, see
the TACL Reference Manual and the Guardian User's Guide.
PATHMON Configuration File
The PATHMON process maintains a configuration file containing configuration
information about the objects it controls. This file is usually called:
$default-volume.default-subvolume.PATHCTL
If a file named PATHCTL does not already exist, the PATHMON process automatically
creates this file as part of the cold-start operation. The PATHCTL file is an Enscribe
key-sequenced file and has a file code of 310. You can change the name of this file by
using the TACL ASSIGN command and by referring to the logical file PATHCTL before
running the PATHMON process. For more information about the PATHMON
configuration file, including restrictions on the use of multiple configuration files, see
the TS/MP System Management Manual.
Guardian File Names
Each disk file in the Guardian file-system is identified by a unique, symbolic file name,
described in the following paragraphs.
File Name Format
The name, and therefore the location, of a Guardian disk file is determined in four
parts:
•
\nodeIdentifies a specific system within a network
•
$volumeIdentifies a physical disk pack mounted on a disk unit
•
subvolumeIdentifies a disk file as a member of a related set of files as defined
by the user
•
file–identifierIdentifies a particular file within the subvolume
