2
3 Syntax as a command: complete_volume_dump -control_args
4
5
6 Function: starts a complete volume dump. For each physical volume
7 specified, all segments and directories are dumped.

9
10 Control arguments:
11 -accounting
12 specifies that accounting data is to be collected in the directory
13 >sc1>volume_backup_accounts for later processing. The default is
14 off. This control argument is optional.
15 -auto
16 specifies that dump volumes are to be selected from the default dump
17 volume pool, which is also known as the tape pool or the volume pool
18 segment, and is located at >ddd>volume_backup>Volume_Dumper.volumes.
19 For more information, see the description of the manage_volume_pool
20 command in the Multics Commands and Active Functions manual, Order
21 No. AG92. This control argument is optional.
22
23
24 -control entry
25 where entry is the entryname of the control segment. The suffix
26 "dump" is assumed if not specified. This control argument is
27 required.
28 -error_on
29 specifies that all error messages are to be written to the
30 error_output switch as well as to the dmpr_err.mm/dd/yy.hhmm.s
31 segment. The default is that error messages are written only to the
32 dmpr_err.mm/dd/yy.hhmm.s segment. This control argument is
33 optional.
34
35
36 -manual_free
37 specifies that if purging is done, volumes must be freed from the
38 volume pool manually. This means that dump volumes are purged from
39 the respective volume logs but are not reused until they are marked
40 as free in the volume pool. The default is to automatically free
41 volumes in the volume pool. This control argument should be used
42 only with the -auto control argument.
43 -mod_after DT
44 where DT is a time acceptable to the convert_date_to_binary_
45 subroutine. Only those segments and directories whose
46 date-time-modified exceeds DT are dumped. This control argument is
47 optional.
48
49
50 -names
51 specifies that the entire name space of each directory dumped is
52 recorded online. This online data base significantly improves the
53 performance of the volume retriever, but requires a large amount of
54 disk storage. This control argument is optional.
55 -no_object
56 specifies that segments and directories are not to be dumped. Only
57 the header information that describes them is dumped. The default
58 is to dump the segments and directories. This control argument is
59 optional.
60 -no_purge_volume_log, -npvl
61 specifies that the volume log of each physical volume dumped is NOT
62 to be purged using the values set with the set_volume_log command.
63 Default.
64
65
66 -no_trace
67 specifies that the dumping process is not be be traced. This is the
68 default.
69 -no_update
70 specifies that the VTOCE of segments and directories dumped is not
71 to be updated. This speeds up dumping at the cost of invalidating
72 the dtd and volume ID fields of the VTOCE. The default is to update
73 the VTOCE. This control argument is optional.
74 -operator STR
75 where STR specifies the name or initials of the user. This control
76 argument is required.
77
78
79 -output_volume_desc STR
80 where STR specifies a value to be used instead of the default attach
81 description. The dump volume name is inserted in the attach
82 description at the first occurrence of the string "^a" in the attach
83 description. The default attach description is:
84
85 tape_mult_ ^a -write -system
86
87 If STR contains blanks, it must be enclosed in quotation marks.
88 This control argument is optional.
89
90
91 -preattach N
92 specifies that N volumes are to be preattached before writing on the
93 first volume. This allows a site to operate the volume dumper
94 without user intervention, by premounting the requested or supplied
95 volumes. The default is to not preattach. This control argument is
96 optional.
97 -purge_volume_log, -pvl
98 specifies that the volume log of each physical volume dumped is to
99 be purged using the values set with the set_volume_log command.
100 -restart STR
101 specifies that the dump should restart from physical volume STR,
102 which is implicitly or explicitly defined in the control file. The
103 default is to start at the last volume dumped. This control
104 argument is optional.
105
106
107 -trace
108 specifies that the dumping process is to be traced. As each segment
109 is dumped to the output tape volume, its unique id and pathname is
110 written to the user_output I/O switch.
111 -working_dir, -wd
112 specifies that the volume backup databases are to be searched for
113 relative to the working directory. The default is to search
114 relative to the >ddd>volume_backup directory. This control argument
115 is optional.
116
117
118 Notes: If a dump terminates abnormally, reinvoke the
119 complete_volume_dump command. The dump will be restarted and reload
120 groups will be kept consistent. If the dump terminates again, use the
121 new_proc command to clean up the dumper process. Then reinvoke the
122 complete_volume_dump command with the -restart argument. The -restart
123 argument must be used after a new_proc to keep reload groups
124 consistent.
