Example Embodiment
[0033] Example one
[0034] Such as figure 1 As shown, a multi-path status monitoring method includes the following steps:
[0035] S1. Judge the path failure by periodically querying the multipath output information;
[0036] S2. Perform path fault diagnosis and judgment process according to storage type classification;
[0037] S3. Send the link failure point to the monitoring terminal.
Example Embodiment
[0038] Example two
[0039] Such as figure 2 As shown, a multi-path status monitoring method includes the following steps:
[0040] S1. Set the interval time and execution authority of periodic query.
[0041] S2. Periodically query the multipath output information, and when the faulty keyword exists in the state of a path in the multipath status information, it will be determined that the path is faulty.
[0042] S3. Determine whether the storage type is IP storage, test whether the storage service port, storage management port, and switch management port communicate normally, and determine the point of link failure.
[0043] S4. Determine whether the storage type is FC storage, test whether the storage optical port, storage management port, and fiber switch management port communicate normally, and determine the point of link failure.
[0044] S5. Send the link failure point to the monitoring terminal.
Example Embodiment
[0045] Example three
[0046] A multi-path status monitoring method, including the following steps:
[0047] S1. Install multipath software, copy the script to the Linux system directory, and use chmod+x to add executable permissions to the script.
[0048] S2. Use the Crontab command under the Linux system to write instructions for a specified time or interval, so that the system automatically executes the script program according to the timing plan.
[0049] S3. The program automatically monitors the status of multipath according to the timing plan. When the script detects the faulty keyword in the status of a path in the multipath status information, it will determine that the path is faulty, and then execute the fault. Diagnosis process.
[0050] S4. When the script program finds a multi-path transmission failure, first use the iscsiadm command in the Linux system to find out whether there is link information for IP storage in the system. If the information about the IP storage con...
