Interconnect module removal and replacement

Removing or replacing Virtual Connect modules

It is not necessary to remove the module from the domain if the module is not in use. The module is removed automatically from the domain without user intervention.

Replacing a primary or backup VC module with a different VC module type is not allowed without first deleting the domain.

If a module is in use and configured by the domain at the time it is physically removed from an enclosure, then the module is marked as MISSING, and can only be replaced by a module of the same model and type. If an in-use module is replaced by a module of a different type, then it is marked as INCOMPATIBLE by the domain.

If a module being physically removed is the primary module of a primary bay pair, then it is marked as MISSING and can only be replaced by a module of the same type.

A VC-Enet module is in use if any of the following conditions exist:•The module physically exists in an interconnect bay using VC release prior to 3.00.

•The uplink and downlink ports of the module are being used by one or more networks, uplink sets, or profiles.

•Port monitoring is enabled for the interconnect module.A VC-FC capable module is in use if any the following conditions exist:

•The module physically exists in an interconnect bay using VC release prior to 3.00.

•The uplink ports of the module are being used by a fabric that is being used by a profile.

•The module is part of a FC bay group in a multi-enclosure configuration where other FC modules exist in the bay group.

If a VC-FC module is replaced with a spare VC-FC module without powering down the servers, and if the server has profiles assigned to it with FC connections, servers are allowed to log in for a brief period through an uplink of the new module, provided that the uplink is connected to the fabric. Approximately 8 seconds after discovering the new VC-FC module, VCM configures it with the correct information, mapping downlinks to the correct uplinks. To work around this problem, power down the servers in the enclosure before replacing or swapping FC modules. Alternatively, do not connect the VC-FC uplinks to the fabric until VCM recognizes and configures the VC-FC module.

When adding VC interconnect modules to a VC managed enclosure, wait until the modules have been fully integrated into the current domain before attempting to make configuration changes to the VC domain. These changes include adding or editing networks, fabrics, profiles, and shared uplink sets. Verify that the domain status is clear for the newly added interconnect module before making any changes to the configuration.

Modifying the configuration before the integration is complete can cause unexpected behavior such as incorrect/invalid connections in a profile.
