If you have… You must…
DA volumes in a host cluster that contains FC-
only hosts, and you want to add iSCSI-only
hosts
Remove any DA volumes belonging to the
cluster, using one of these options.
DA volumes cannot be
shared in this scenario.
•
If you do not want to share DA volumes
between hosts, remap all DA volumes to
individual FC hosts within the cluster.
•
Segregate the iSCSI-only hosts into their
own host cluster, and keep the FC host
cluster as is (with shared DA volumes).
•
Add an FC HBA to the iSCSI-only hosts to
allow for sharing of both DA and non-DA
volumes.
DA volumes in a host cluster that contains FC-
only hosts, or DA volumes that are mapped to
an individual FC host partition
No action is needed before applying the
feature pack. DA volumes will remain mapped
to their respective FC host.
No partitions defined No action is needed before applying the
feature pack because no volumes are currently
mapped. After converting the host protocol,
follow the proper procedure to create host
partitions and, if desired, host clusters.
Converting from iSCSI to FC/iSCSI (not applicable to controllers without two base-board
ports on the rear)
•
If you plan to convert a port that is being used for mirroring, you must move the mirroring
relationships to a port that will remain iSCSI after the conversion.
Otherwise, the communication link might be down after the conversion because of a protocol
mismatch between the new FC port on the local array and the existing iSCSI port on the remote
array.
•
If you plan to convert the ports that are not being used for mirroring, asynchronous mirroring
operations will be unaffected.
Before applying the feature pack, you should confirm that all mirror consistency groups are
synchronized. After applying the feature pack, you should test the communication between the
local storage array and the remote storage array.
