6 Request that the Collector operator initiate
another series of polling sessions.
Notes:
Note 1: The AMA data file with VS 15 is the file where polling has encountered an improper data block. It is the first primary
file after a list of secondary files. Of the 251 blocks in this file, all but the last 60 have been correctly transferred to the
Collector and marked as secondary. Since the Collector polls for 100 block increments, the range of the improper block starts
with the 60 primary blocks in VS 15 and ends 100 blocks later. Proceed to step 2.
Note 2: When an out of sequence condition is detected, the block sequence No. used in the command, not the improper
sequence number displayed in the block header, should be noted. Continue to examine blocks (repeat step 3 above) until the
block sequence number in the block header matches the sequence number asked for in the command. (Also note this
sequence number.) This block marks the end of the range of bad blocks found. These two noted sequence numbers mark
the beginning and end of the range of bad blocks. The second number noted is used to create an AMA index file with the first
Primary block equal to this sequence number.
