Requirements
When creating a Connectivity Service there are two use cases as follows:
Standard Use Case
In the standard case one or more FCInitiatorEndpoint requirements are given in conjunction with
one or more FCTargetEndpoint requirements. For each and every endpoint requirement the sub
requirement FCWWN is required.
SPM will interpret these requirements as follows. SPM will check that all the given endpoints are
on the same network. Then it will check that each initiator can communicate with each of the targets
(the network is open, they are already zoned together, or zoning automation can take place to
put then in a zone together). However since we will be using the SIZ policy we will not check
connectivity between the initiator requirements only the initiator to all targets.
If the endpoints as described above can be connected or already are then one and only one
candidate is returned to signify that yes the desired endpoints requirements can be or are already
connected together.
Proxy Use Case
The proxy case is much like the standard case with a couple of caveats. First the sub requirement
FCProxyWWN is given in addition to the FCWWN for a FCInitiatorEndpoint requirement.
Since FCWWN doesn’t necessarily have to exist as of yet (for example, the host may not have
logged into the fabric as of yet). SPM will use the given FCProxyWWN requirement, which is the
WWN of another endpoint that has already logged into the fabric and is known to SPM (typically
this is the uplink port of a Blade enclosure, but could be any known port). The FCProxyWWN is
used to identify where the FCWWN will live once it is powered up and allows SPM to generate
candidates for it as if it already exists.
Unmanaged networks
SANs that have no automated management path from SPM (unmanaged network) can still be
imported into the SPM catalog. Using an unmanaged network is recommended for a small number
of storage devices only.
For additional information regarding unmanaged networks, please refer to Working with
unmanaged networks.
