Provisioning Storage Access in the SAN
Storage access consists of zone provisioning and storage selective LUN
presentation, each of which is commonly provisioned per initiator WWPN. Two
main paths are available for approaching storage access:
Pre-Provisioning
With pre-provisioning, note the initiator WWPN and manually modify fabric zoning
and storage selective LUN presentation to allow the appropriate access for the
initiator.
The initiator WWPN can be seen at the bottom of the screen in the FCoE boot
target configuration window.
The initiator WWPN can also be directly inferred from the FIP MAC address
associated with the interface(s) planned for boot. Two MAC addresses are printed
on stickers attached to the SFP+ cage on your adapter. The FIP MAC ends in an
odd digit. The WWPN is 20:00: + <FIP MAC>. For example, if the FIP MAC is
00:10:18:11:22:33, then the WWPN will be 20:00:00:10:18:11:22:33.
CTRL+R Method
The CTRL+R method allows you to use the boot initiator to bring up the link and
login into all available fabrics and targets. Using this method, you can ensure that
the initiator is logged into the fabric/target before making provisioning changes,
and as such, can provision without manually typing in WWPNs.
1.
Configure at least one boot target through CCM as described above.
2.
Allow the system to attempt to boot through the selected initiator.
3.
Once the initiator boot starts, it will commence with DCBX sync, FIP
Discovery, Fabric Login, Target Login, and LUN readiness checks. As each
of these phases completes, if the initiator is unable to proceed to the next
phase, MBA will present the option to press CTRL+R.
4.
Once CTRL+R has been activated, the boot initiator will maintain a link in
whatever phase has most recently succeeded and allow you time to make
the necessary provisioning corrections to proceed to the next phase.
NOTE
The default WWPN is 20:00: + <FIP MAC>. The default WWNN is 10:00: +
<FIP MAC>.
