Step 4 Run the stp enable command to enable switch loop suppression.
Step 5 Run the display stp command to verify that STP has been enabled, as shown in Figure 1-2.

Step 6 Run the save command to save configurations.
Step 7 Run the ping command on the ISM server to check whether nodes can be pinged. If node communications is abnormal, restart abnormal nodes from MDSs to OSNs.
Step 8 Check the storage domain status on the ISM interface. If the status is Recovery or Normal, the storage domain is available. If the status is Faulty, wait 10 minutes. If the status is still Faulty after 10 minutes, contact technical support engineers.
Step 9 Check the status of wushan CA. If the status is Faulty, you need to remount the client.
1. Run the umount/mnt/CA command to uninstall the client.
2. Run the mount.wfs -t wlite220.127.116.11:18.104.22.168:/ok/default /mnt/CA command to mount the client again.
22.214.171.124 indicates the IP address of the active MDS, 126.96.36.199 indicates the IP address of the standby MDS, ok indicates the name of the related storage domain, default indicates the namespace, and /mnt/CA indicates the client mounting point.
Step 10 Verify that the status of the storage domain and client are Normal. Then log in to the client and run the following command:
touch testfile echo “123456” >> testfile cat testfile
If the storage domain and client remain abnormal, contact technical support engineers.
Check whether an error message is displayed. If no, the fault is removed. If yes, contact technical support engineers.
