. Creating a Pre Snapshot with Snapper, 14.2.1.2. When you use the auto-bind keyword to create an initiator and generate a WWNN for an initiator, your Server Switch creates a virtual port (NL_Port) that represents the initiator on every physical port on the FC gateway. Example 1: Listing all HBA ports The following command lists all fibre channel HBA ports on the host: # fcinfo hba-port HBA Port WWN: 210000e08b074cb5 OS Device Name: /dev/cfg/c1 Manufacturer: QLogic Corp.

Maximum number of times that the initiator unsuccessfully sends data to a LU before the initiator identifies the LU as inaccessible. Monitoring NVDIMM health using S.M.A.R.T. Grants the initiator access to select ports or LUNs when you use the no keyword. The above output shows the system bus has detected two QLogic HBAs. Otherwise, include the no keyword at the beginning of the command string to disable this feature. Alphanumeric description to assign to the LU. All SCSI commands have a FC equivalent, and FC has a few extra ones that allow for networking. Assign multiple partition keys by appending a colon, then the next key (aa:aa:bb:bb:cc:cc:dd:dd).
