Abstract

The present invention relates to systems and methods for configuring a data storage system. One method adds a Fibre Channel device to the loop by beaconing first and second ports, displaying instructions to connect a cable, receiving an indication the cable is connected, enabling the first port, initiating a LIP, and verifying whether the cable is connected. Another method removes a Fibre Channel device from the loop by beaconing the second port, bypassing the first port, initiating a LIP, beaconing the first port, displaying instructions for disconnecting the cable, and receiving an indication the cable is disconnected. A system includes means for displaying instructions to add a Fibre Channel device on the loop and a management controller for beaconing first and second ports, displaying instructions to connect a cable, receiving an indication that the cable is connected, enabling the first port, initiating a LIP, and verifying whether the cable is connected properly. Another system includes means for displaying instructions to remove a Fibre Channel device from the loop and a management controller programmed for beaconing the second port, bypassing the first port, initiating a LIP, beaconing the first port, displaying instructions to disconnect a cable, receiving an indication that the cable is disconnected, and verifying whether the cable is disconnected.

(b) beaconing the second port;

(c) displaying instructions to a user to connect a cable between the first port and the second port;

(d) receiving an indication that the cable is connected between the first port and the second port;

(e) enabling the first port;

(f) initiating a LIP on the Fibre Channel loop;

(g) verifying whether the cable is connected between the first port and the second port; and

(h) suspending the active data traffic on the Fibre Channel loop before step (e) and resuming the active data traffic on the Fibre Channel loop after step (f).

2. The method of claim 1, wherein the beaconing in steps (a) and (b) includes turning on a first light corresponding to the first port and a second light corresponding to the second port.

3. The method of claim 1, wherein the beaconing in steps (a) and (b) includes changing the color of a first light corresponding to the first port and a second light corresponding to the second port.

4. The method of claim 1, wherein before the beaconing in steps (a) and (b), performing a step of turning off all lights of the data storage system.

5. The method of claim 1, wherein the displaying in step (c) is on a management client.

6. The method of claim 1, wherein the receiving in step (d) includes automatically detecting the cable is connected between the first port and the second port.

7. The method of claim 1, wherein the receiving in step (d) includes receiving user input indicating the cable is connected between the first port and the second port.

8. The method of claim 1, wherein the verifying in step (g) is by determining the identity for the second port during the LIP.

9. The method of claim 1, further comprising step (g) determining that the cable is not connected between the first port and the second port, wherein the method repeats steps (a) through (g).

10. The method of claim 1, wherein the first part is located on a node of a first data storage subsystem and wherein the second port is located on a node of a second data storage subsystem.

11. The method of claim 1, wherein the first port is located on a node of a first host and wherein the second port is located on a node of a first data storage subsystem.

12. The method of claim 1, wherein the first port is located on a node of a first host and wherein the second port is located on a node of a second host.

13. The method of claim 1, wherein the second port beaconing occurs after a Fibre Channel device having the second port is turned on, confirms normal operation and does not sense a connection at the second port.

33. The method of claim 13, wherein the Fibre Channel device is a host.

34. The method of claim 13, wherein the Fibre Channel device is a data storage subsystem.

14. A method of configuring a data storage system processing I/O requests and having active data traffic on a Fibre Channel loop including a cable connecting a first port to a second port, comprising:

(a) beaconing the second port;

(b) bypassing the first port;

(c) initiating a LIP on the Fibre Channel loop having the bypassed first port;

(d) beaconing the first port;

(e) displaying instructions for disconnecting the cable between the first port and the second port;

(f) receiving an indication that the cable is disconnected; and

(g) suspending the active data traffic on the Fibre Channel loop before step (b) and resuming the active data traffic on the Fibre Channel loop after step (c).

15. The method of claim 14, wherein the beaconing in steps (a) and (d) includes turning on a first light corresponding to the first port and a second light corresponding to the second port.

16. The method of claim 14, wherein the beaconing in steps (a) and (d) includes changing the color of a first light corresponding to the first port and a second light corresponding to the second port.
