Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a method, device and equipment for setting a WWPN of an FC physical port. Background Art

[0002] FC (Fibre Channel) protocol is the original protocol of Storage Area Network (SAN) and is still the most mature and stable protocol. It has outstanding advantages in terms of ease of management and stability and reliability.

[0003] When the FC card of the storage array fails, a new card will be replaced online. However, since the new card will have a new WWPN (world wide port name), the user may need to change the previous FC switch configuration, which poses a risk to the stability of the FC storage network. For example, adjusting the switch configuration usually causes business interruption of the entire switch. Secondly, if human operation errors occur, more serious losses will occur. For some critical businesses, this risk is unacceptable.

[0004] In the prior art, FC card suppliers provide a tool for modifying WWPN. The principle of these tools is to modify the NVRAM (Non-Volatile Random Access Memory) in the FC card through the firmware interface. Since the preset WWPN of the FC card is stored in the NVRAM, the WWPN of the FC card can be modified by modifying the NVRAM, and the modified value is effective regardless of how the array is restarted. However, since NVRAM mainly stores the static configuration information of the FC card, it is not suitable for multiple writes. Multiple writes will increase the failure probability of NVRAM. In addition, the information in NVRAM is very critical to the operation of the FC card. If an error is written or a failure occurs, the FC card will be directly unavailable and difficult to recover. Summary of the invention

[0005] The present invention provides a method for setting the wwpn of an FC physical port, which is used to reset the wwpn without modifying the NVRAM in the FC card, avoiding the problem that multiple writes will increase the failure probability of the NVRAM, and ensuring that the storage array can work normally after the card is replaced.

[0008] According to the array unique identifier, obtain a first wwpn;

[0009] Replacing a second wwpn with the first wwpn, wherein the second wwpn is obtained from a Fibre Channel (FC) card of the storage array;

[0010] Initializing the firmware of the FC card using the first wwpn;

Therefore, in the embodiment of the present application, the first wwpn set by the storage array is used for firmware initialization and switching network login, and the second wwpn is always stored in the FC card, but is not used, and the first wwpn is used every time. Therefore, in the embodiment of the present application, the wwpn is reset without modifying the NVRAM in the FC card, avoiding the problem that multiple writes will increase the probability of NVRAM failure, and ensuring that the storage array can work normally after the card is replaced.

[0022] In a possible implementation manner, the second wwpn is obtained by:

[0023] triggering a hot-swap operation of the FC driver to drive the FC card;

[0024] After the FC card is driven, a second wwpn in the FC card is obtained.

[0025] In the above method, the hot-swap operation of the FC driver is triggered to drive the FC card to obtain the second wwpn in the FC card, thereby ensuring that the second wwpn can be obtained smoothly.

[0026] In a possible implementation manner, before triggering the hot-swap operation of the FC driver, the process includes:

[0027] The FC card is powered off and then powered on, so that the FC card triggers a hot-swap operation of the FC drive.

Therefore, in the embodiment of the present application, the wwpn is reset without modifying the NVRAM in the FC card, avoiding the problem that multiple writes will increase the failure probability of the NVRAM, and ensuring that the storage array can work normally after the card is replaced.

[0068] In the prior art, FC card suppliers provide a tool for modifying WWPN. The principle of these tools is to modify the NVRAM (Non-Volatile Random Access Memory) in the FC card through the firmware interface. Since the preset WWPN of the FC card is stored in the NVRAM, the WWPN of the FC card can be modified by modifying the NVRAM, and the modified value is effective regardless of how the array is restarted. However, since NVRAM mainly stores the static configuration information of the FC card, it is not suitable for multiple writes. Multiple writes will increase the failure probability of NVRAM. In addition, the information in NVRAM is very critical to the operation of the FC card. If an error is written or a failure occurs, the FC card will be directly unavailable and difficult to recover.

Therefore, in the embodiment of the present application, the first wwpn set by the storage array is used for firmware initialization and switching network login, the second wwpn is always stored in the FC card, but is not used, and the first wwpn is used every time. Therefore, in the embodiment of the present application, the wwpn is reset without modifying the NVRAM in the FC card, avoiding the problem that multiple writes will increase the probability of NVRAM failure, and ensuring that the storage array can work normally after the card is replaced.

[0094] Step 301: After driving the FC card, obtain the second wwpn in the FC card;

[0095] Step 302: Initialize the FC firmware using the second wwpn;

[0096] Step 303: Log in to the exchange network using the second wwpn;

[0097] Step 304: receiving a global port name wwpn setting instruction sent by a user;

[0098] Step 305: obtaining the array unique identifier of the storage array based on the array license license in the wwpn setting instruction;
