The post will share a case for an alarm is reported that UltraPath is not installed in OceanStor S5600T V200R002 or install UltraPath is of an early version.
Problem Description
UltraPath is not installed or the installed UltraPath is of an early version.
Handling
Process
1. Run the upadmin show version command to check the version information and determine whether UltraPath is installed. If no version information is displayed, install UltraPath for the corresponding system.
2. If the version information is displayed, UltraPath is installed. Check whether the UltraPath configuration file is normal by querying whether the issue configuration file exists under the /etc directory. The file is deleted after being backed up and the issue file is empty. As a result, UltraPath is invalid.
3. Log in
as user root and run the cp /etc/issue.bak_20150706 /etc/issue
command to copy the backup configuration file to the original directory. After
modifying the configuration file, restart the storage device to make the
modification take effect. Confirm with the customer to restart the device to
avoid impact on services and data.
4. After
the restart, check and verify the modification by running the upadmin show
version, upadmin show vlun, and upadmin show path commands.
If the information about the UltraPath version, vLUN, and path is displayed,
the modification is successful.
5. After the recovery is
completed successfully, inspect the device and ensure that no failed check item
exists. In addition, related alarms on the ISM are cleared. Verify whether
services are running properly.
Root
Cause
1.
Free initiators that are not configured for the host exist in the storage
system.
2. UltraPath is installed but the configuration file is changed after
security hardening. As a result, UltraPath alarms are generated.
3. The storage system is connected to a cluster, but the
initiator-target link is not registered.
Suggestions
1.
Periodically inspect devices and check whether alarms are generated.
2. Log in to ISM to check the running status. If any problem occurs, contact Huawei technical support.
