Guide to check After the Replacement with Services Suspended

[Procedure]

Perform the following steps after the interface card is replaced.

1. Check whether the system status is normal.

   #tail -200 /var/log/vmkernel.log

   Check whether any fault about iSCSI and disks exists. If such a fault exists, ask the system administrator to locate and solve the fault. If the fault is not solved, subsequent operations are not allowed.

2. Check whether the established iSCSI sessions are correct.

   #esxcli iscsi session list

   The information (displayed in the command output) of links established between the host and storage must be the same as that before replacing the interface card.

3. Run the disk scanning command.

   #esxcfg-rescan -A

4. Check whether the number of generated aggregated disks is the same as that of physical disks.

   #esxcli upadm show vlun

   
   

   The number of generated aggregated disks must be the same as that of physical disks.

5. Check disk path status and parameter settings.

   #esxcli upadm show path

   If any path is found in Fault state, wait about 120 minutes. The path will automatically be deleted.

6. Collect host information.

   1. Operating system version

      #vmware -v

   2. Host name

      #hostname

   3. UltraPath version and configuration

      #esxcli upadm show version

   4. iSCSI link sessions

      #esxcli iscsi session list

   5. Information about disks and paths

      #esxcli storage core device list

      #esxcli upadm show vlun

      #esxcli upadm show path

   6. Host error logs

      #tail -200 /var/log/vmkernel.log

      Check whether any host error exists after the change. If any error exists, analyze the causes and inform the application system that the storage space cannot be used before the problem is solved.
