Data center does a DEMAND POLL on the unpolled data in the corrupt version. The data
center should now be able to retrieve the previously unpolled data from version 108 by
executing a DEMAND POLL, starting at sequence number 008699, for 49 blocks.
This starting sequence number for the demand polling is calculated by using the original
sequence number of version 108 (007413) and adding the blocks in version 108 (1335) to
arrive at the correct next sequence number, 008748. From this sequence number, the 49
blocks of unpolled data in version 108 are subtracted (008748 minus 49) to arrive at the
actual starting sequence number, 008699. This is where the data center should start the
demand poll.
27
Delete the temporary AMA index file. After the data center confirms that they have
successfully retrieved the previously unpolled 49 blocks from the BMC, remove the
temporary AMA index file. This does not remove the AMA data (the AMACRD files), but it
does remove the AMAIDX file. The following command will remove the AMAIDX file, but a
new one will be built in a subsequent step. (The new AMAIDX file that will be built shall
contain the correct version numbers.)
