-- This procedure should be run only by Rational personnel or under their
-- direction!
-- Performs an analysis of the disk structure(s)
--
-- If there is an inconsistency in the internal disk structure(s) Backup will
-- typically fail with an !Lrm.Assertion error and then log a message such as:
--
-- Backup Inconsistent_Space space = <258,Module,156694>
--
-- This procedure gathers information about the disk in the same fashion as
-- Backup. Whenever something inconsistent is detected, a diagnostic message
-- is displayed. Unlike Backup which would then immediately terminate, this
-- procedure will attempt to continue and should report all inconsistencies.
--
-- This procedure will take a significant amount of time; for large disks, it
-- will take 30 or more minutes for each disk. The basic algorithm it uses is:
--
-- For each disk volume
-- Check all VPs
-- For Each Segment
-- Check each disk block associated with this segment
-- (Note: since a disk block can be shared among segments, disk
-- blocks can be "visited" more than once.)
-- End loop
-- End loop
--
--
-- NOTES
-- 1. This procedure must be scheduled to avoid overlap with the Disk client
-- and/or Backup. By default, if disk collection starts during this
-- procedure, this procedure will be killed. This default behavior can
-- be changed by executing !Tools.Disk_Daemon.Set_Backup_Killing(false)
--
-- 2. The Diagnostic messages display all information in DECIMAL
--
-- It should be noted that a likely outcome when a corrupted system
-- is discovered by this procedure is a system crash.
