There is no feedback to the user on the status of the standby copy. If an error is
encountered during the copy or validation process on the standby, an error is
logged in the software error log. Because the data consistency audit discovers
that the two patch files are inconsistent, the user must manually copy the valid file
on the active processor over to the standby processor.
The software does not indicate when the copy has completed, so scripts run by
the TSC must not issue an immediate reset on High or Critical Reliability Systems.
This interrupts the copy and guarantees that the field update files on the two
processors are inconsistent. This problem can be avoided by using one of the
following techniques:
■ Use two scripts: the first to apply the patch and a second (run later) to issue
the reset that applies the patch. This requires two calls to each duplicated
switch.
■ Put a delay into the scripts, causing the scripts to wait a period of time after
downloading the file and before issuing the reset. This requires only one
call, but the amount of delay time required is not well defined, as it varies
by system load.
■ Use a manual means of detecting when the copy has completed: either a
“PASS” on the data consistency audit or a match on the List Configuration
Software form. This requires only one call and introduces less delay in
requesting the reset.

■ The form displayed for the list configuration software-vintage command
has been modified to reflect the changes imposed by the flash architecture.
The list configuration software command allows INADS to determine
with one query the hardware configuration, software vintage, and patch
identifier.
■ There is no interaction with routine periodic or scheduled maintenance,
because patches are only applied on restarts before the system is in
normal operation.
