The Question is:
When performing zoning changes on a Brocade 12000 Core Fibre Switch. Disks on
the VMS servers go into mount verification. Is there something we can do with
the HBA to stop this ?
The Answer is :
Short answer: No.
Longer answer: Mount verification occurs when an error that is deemed
retryable and potentially fixable is returned on an I/O. When fibre
channel switches are reconfigured, a temporary loss of connectivity
between host and device happens. Any I/O attempted during that outage
will cause mount verification to begin. That is the expected OpenVMS
response to retryable I/O errors.
As long as the SYSGEN parameter MVTIMEOUT (defaults to 3600 seconds)
is not set to some very low value (less than a minute), the devices
should exit mount verification when connectivity is restored. If
MVTIMEOUT is set to expire before connectivity is restored, mount
verification will time out, requiring a remount to make the device
