Managing vHBAs Guidelines for Managing vHBAs When managing vHBAs, consider the following guidelines and restrictions: • The Cisco UCS P81E V irtual Interface Card and Cisco UCS VIC1225 V irtual Interface Card provide two vHBAs (fc0 and fc1). Y ou can create up to 16 additional vHBAs on these adapter cards.

PLOGI Timeout field Step 14 In the SCSI I/O area, review the information in the following fields: Description Name The number of SCSI I/O queue resources the system should allocate.
Step 5 In the tabbed menu below the Adapter Cards area, click the vHBAs tab. Step 6 In the Host Fibre Channel Interfaces area, select a vHBA from the table. Step 7 Click Properties to open the vHBA Pr operties dialog box. Step 8 In the General area, update the following fields: Description Name The name of the virtual HBA.
Description Name The data rate limit for traffic on this vHBA, in Mbps. If you want this vHBA to have an unlimited data rate, select OFF . Otherwise, click the second radio button and enter an integer between 1 and 10,000. This option cannot be used in NIV mode.
Description Name The number of milliseconds the uplink port should be offline before it informs the system that the uplink port is down and fabric connectivity has been lost.
Description Name The number of times that the system tries to log in to the fabric after the first failure. T o specify an unlimited number of retries, select the INFINITE radio button. Otherwise select the second radio button and enter an integer into the corresponding field.
Step 16 Click Save Changes . Creating a vHBA The adapter provides two permanent vHBAs. If NIV mode is enabled, you can create up to 16 additional vHBAs. Procedure Step 1 In the Navigation pane, click the Server tab. Step 2 On the Server tab, click Inventory .
Deleting a vHBA Procedure Step 1 In the Navigation pane, click the Server tab. Step 2 On the Server tab, click Inventory . Step 3 In the Inventory pane, click the Network Adapters tab.
Description Name The W orld W ide Port Name (WWPN) that corresponds to the location of the boot image. Enter the WWPN in the format hh:hh:hh:hh:hh:hh:hh:hh. T arget WWPN field The LUN ID that corresponds to the location of the boot image. Enter an ID between 0 and 255.
