Whenever an IPS or CSM blade is in an MDS, the MDS will login to storage just the same as a real initiator would. We send Inquiry, Report Luns, and read capacity to learn about the storage out on the SAN. This process is done when the storage device comes online or when manually initiated. However, with auto-poll, we will go thru the discovery process every X number of seconds that can be configured.
This is not on the IPS ports but rather on any FC attached device that registers itself as a target. We use the pwwn seen as the result of show scsi-target internal driver. If the storage has any kind of LUN security, this pwwn will need to be permited or our discovery process will fail due to it being denied.
