Explanation
A VARY SWITCH command requested that a port or
ports be varied ONLINE or OFFLINE to dynamic channel path management.
The request could not be carried out because of the reason given.
Rejection
explanations:
- IS A CHPID PORT
- This port is connected to a channel path. Only ports connected
to subsystems may be varied ONLINE or OFFLINE to dynamic channel path
management.
- IS NOT IMPLEMENTED
- This port is outside the range of switch ports for this model.
- IS NOT INSTALLED
- The port is within the range of implemented ports for the model
but it is not physically present at your installation.
- IS NOT ATTACHED
- This port is installed but is not presently connected to any element.
- IS PORT STATE OFFLINE
- This port is offline to dynamic channel path management due to
its state (for example, it is blocked dedicated, or offline)
- IS SYSTEM STATE INELIGIBLE
- This port is offline because the system has determined that it
is unavailable for dynamic channel path management.
- IS INELIGIBLE FOR DCM
- This port cannot be varied because it is not attached to a DASD
subsystem.
- FAILS VERIFICATION
- This port cannot be varied because the specified switch device
number is not a switch or cannot be determined.
System action
If a range of ports was specified, action may
have been taken only on the valid ports.
Operator response
If this message is unexpected for a particular
port, then correct the original condition. Once the failing condition
is corrected, dynamic channel path management will begin managing
the port as requested.
