Reporting on Disk Files
• If VOL= is given specifying a pool-id, one output detail line is generated
for each extent entirely or partly in each pool space defined for the pool. If
more than one pool space is defined on one real volume, and an extent
overlaps more than one of them, it will be reported once for each pool
space it overlaps. The true starting and ending locations are always
reported, but the number of tracks or blocks reported reflects what is
actually in the pool space being reported on.
CREATE
EXPIRE
Reports the creation date as found in the file's format-1 record. If the date
there is uninitialized (zero), this item contains --/--/--.
Displays the expiration date as found in the file's format-1 record.
If the date there is uninitialized (zero), this item contains —/—/—.
If the date is equal to or later than 2099/366, this item contains —PERM—.
If the date is equal to 2099/365, this item contains -RETAIN-.
EXTENT SEQ
EXTENT TYPE
Indicates that the report is unchanged from the extent segment in the format-
1, format-3, or format-4 record. If the complete on this volume flag is not set
for the file, a plus (+) appears next to this item. This means that the file has
continuation extents on another volume, that it was never closed, or that it
was created by PIOCS and the flag was not set by the access module.
Indicates that the type is decoded from the corresponding binary field in the
format-1, format-3, or format-4 record. Values include the following:
Type Seq# Description
1 any PRIM Primary data extent
2 any OFLO ISAM overflow extent
4 0 MNDX ISAM master index extent
4 not 0 CNDX ISAM cylinder index extent
Other values of the extent type cause that are to be reported.
FILE TYPE
LOW/HIGH EXTENT
Specifies a decoded value derived from the file type indicator bytes in the
VTOC format-1 record. --- is reported if the bits as set do not correspond to
one of the known file types (VSAM, SAM, ISAM or DAM), which can occur with
initialized but never-opened utility files or in general for PIOCS files.
Specifies the physical position at which the extent starts and ends. For CKD
devices it is in CCC-HH format and for FBA, in BBBBB format.
