Procedure 6-28
Polling disks from a nonredundant mode
Step Description
128
Change the disk mode. Enter (at the terminal):
>DISK MODE AO (cr) If the current disk mode is B ONLY.
or
>DISK MODE BO (cr) If the current disk mode is A ONLY.
CAUTION
Do not change the disk mode to PRIME; this would cause one of the
disks to write all of its data onto the other disk. All of the data on the
other disk would be lost.
129
Open a new AMA file. Enter (at the terminal):
>IDXMAINT CREATE FILE AMA (cr)
130
Initiate a polling session
Inform the HOC of your intentions. This session takes the oldest primary AMA data from
the second disk. New AMA data, if received at this time, is saved on this disk. The polling
session ends when all of the oldest primary AMA data has been read from this second
disk.
131
(Optional step) Enter the following command if you wish to keep track of the AMA files to
be polled:
>IDXMAINT DIR CLOSED AMA 200 (cr)
If new AMA is written to both of these disks during these polling sessions, continue by
repeating steps 9-18 to assure that all of the primary data on one of these disks has been
polled. Several combinations of disk mode changes and polling sessions may be required
to poll all of the primary data. To prevent billing data loss, continue this action until no
AMA data is received during a polling session.
