ANALYZE/DISK_STRUCTURE has completed the first two stages, and is beginning Stage 3. Stage 1 involves collection and verification of various volume information. ANALYZE/DISK_STRUCTURE found no problems with volume information. In Stage 2, ANALYZE/DISK_STRUCTURE copies the current version of QUOTA.SYS to working memory, and builds the structure on which a new copy is built during subsequent stages. The first error message is produced by Stage 3. Stage 3 uses the reserved file INDEXF.SYS to locate a variety of file problems. Here, Stage 3 detects a number of invalid file headers. Note that the error message includes the FID and the file name.
This error message is produced during Stage 4, during which ANALYZE/DISK_STRUCTURE builds a current version of BITMAP.SYS, resolves multiple references to extension headers, and corrects discrepancies in the map sections of headers. Here, ANALYZE/DISK_STRUCTURE has found that the specified logical blocks on the specified relative volume were marked allocated in the storage bit map, but were not allocated to a file.
This message marks the beginning of Stage 5. Here, messages stating "lost extension file header" and "invalid file header" indicate that ANALYZE/DISK_STRUCTURE is performing a pass of all entries placed on the invalid backlink map. This map was created in Stage 3.
This message marks the beginning of the second phase of Stage 5, in which ANALYZE/DISK_STRUCTURE confirms that all files in INDEX.SYS are retrievable through the directory structure. Here, the series of "invalid file identification..." messages indicates those directory entries that did not contain a valid file identification.
This message is produced by Stage 6, which is essentially a cleanup phase for lost files. This message indicates that ANALYZE/DISK_STRUCTURE encountered errors during the directory scan that were reported in previous messages. As a result, the file is not entered in directory [SYSLOST].
Here, ANALYZE/DISK_STRUCTURE begins Stage 7, in which it compares values stored in the quota file built during Stage 2 with values in the reserved file QUOTA.SYS. The last three messages here indicate discrepancies between the two files.
Note that no messages were produced during Stage 8. During Stage 8, ANALYZE/DISK_STRUCTURE executes all operations placed on the deferred list, and if you specified /REPAIR, updates QUOTA.SYS and VOLSET.SYS as necessary.

Appendix E
ANALYZE/DISK_STRUCTURE---Usage File

When you specify the /USAGE qualifier, ANALYZE/DISK_STRUCTURE creates a disk usage accounting file. The first record of this file, the identification record, contains a summary of the disk and volume characteristics. The identification record is followed by many file summary records, one record for each file on the disk. Each file summary record contains the owner, size, and name of a file.

The identification record is characterized by the type code USG$K_IDENT in the USG$B_TYPE field of the record. Table E-1 contains a description of all the fields in this record.

**Table E-1 Identification Record Format (Length USG$K_IDENT_LEN)**
Field	Meaning
USG$L_SERIALNUM	Serial number of the volume. This is an octal longword value.
USG$T_STRUCNAM	Volume set name (if the volume is part of a volume set). For a Files-11 Structure Level 1 volume, this field contains binary zeros; for a Files-11 Structure Level 2 or 5 volume that is not part of a volume set, this field contains spaces. The length of this field is USG$S_STRUCNAME.
USG$T_VOLNAME	Volume name of relative volume 1. The length of this field is USG$S_VOLNAME.
USG$T_OWNERNAME	Volume owner name. The length of this field is USG$S_OWNERNAME.
USG$T_FORMAT	Volume format type. For a Files-11 Structure Level 1 volume, this field contains "DECFILE11A"; for a Files-11 Structure Level 2 or 5 volume, this field contains "DECFILE11B". The length of this field is USG$S_FORMAT.
USG$Q_TIME	Quadword system time when this usage file was created. The length of this field is USG$S_TIME.

Each file summary record is characterized by the type code USG$K_FILE in the USG$B_TYPE field of the record. Table E-2 contains a description of all the fields in these records.

**Table E-2 File Record Format (Length USG$K_FILE_LEN)**
Field	Meaning
USG$L_FILEOWNER	File owner UIC. This can be considered as a single longword value or as two word values (USG$W_UICMEMBER and USG$W_UICGROUP).
USG$W_UICMEMBER	The member field of the file owner UIC. This is an octal word value.
USG$W_UICGROUP	The group field of the file owner UIC. This is an octal word value.
USG$L_ALLOCATED	Number of blocks allocated to the file, including file headers. This is a decimal longword value.
USG$L_USED	Number of blocks used, up to and including the end-of-file block. This is a decimal longword value.
USG$W_DIR_LEN	Length of the directory string portion of USG$T_FILESPEC, including the brackets. This is a decimal word value.
USG$W_SPEC_LEN	Length of the complete file specification in USG$T_FILESPEC. This is a decimal word value.
USG$T_FILESPEC	File specification, in the following format: [dir]nam.typ;ver This field is of variable length. A file that has more than one directory entry is listed under the first file specification found. A lost file has an empty directory string "[]" and the file name is taken from the file header. In some cases this information does not exist; you must take this into consideration when you write application programs to process the usage file. The length of this field is USG$S_FILESPEC.

The symbolic names referenced in both the identification and the file summary records are defined in the system definition macro $USGDEF. The length of the identification record is USG$K_IDENT_LEN. The length of a file summary record is USG$K_FILE_LEN.

Appendix F
Security Audit Message Format

This appendix describes the format of the auditing messages written to the security auditing log file. The default audit log file SECURITY.AUDIT$JOURNAL is created by default in the SYS$COMMON:[SYSMGR] directory.

Each security audit record consists of a header packet followed by one or more data packets, as shown in Figure F-1. The number of data packets depends on the type of information being sent. This appendix describes the format of the audit header and its data packets as well as the contents of the data packets.

Figure F-1 Format of a Security Audit Message

F.1 Audit Header Packet

Table F-1 describes the fields contained in Figure F-2.

Figure F-2 Audit Header Packet Format

**Table F-1 Description of the Audit Header Fields**
Field	Symbolic Offset	Contents
Type	NSA$W_RECORD_TYPE	Indicates the type of event that has occurred. See Table F-2 for details.
Subtype	NSA$W_RECORD_SUBTYPE	Further defines the type of event that has occurred. See Table F-2 for details.
Flags	NSA$W_FLAGS	Identifies any flags associated with the audited event. See Table F-3 for details. Reserved to HP. (Word)
Packet count	NSA$W_PACKET_COUNT	Number of data packets in the audit record. (Word)
Record size	NSA$W_RECORD_SIZE	Total size of the audit message; the size represents the header packet plus all its data packets. (Word)
Version	NSA$C_VERSION_3	Indicates the version of the security auditing facility. The symbol NSA$C_VERSION_3 indicates the current version. (Byte)
Facility	NSA$W_FACILITY	The facility code for the generated event. By default, this field is zero, indicating a system-generated event. (Word)

When you enter subtypes, do not include a prefix, as shown in Table F-2.

Symbols representing the types or subtypes of security events are listed in Table F-2. For each audit event record type defined by NSA$W_RECORD_TYPE, there is a record subtype defined by the symbol NSA$W_RECORD_SUBTYPE, which further defines the event.
