Answer
The validity period of the default HyperMetro arbitration certificate is 10 years (start from
September 2015). The arbitration certificate will become invalid if the system time of the
quorum server or a storage array is incorrectly set to a value that exceeds the validity period
of the certificate.
Possible causes are as follows:
l The system time of the quorum server is incorrectly set to a value that exceeds the
validity period of the default arbitration certificate. As a result, the quorum link fails to
be added.
l The system time of a storage array is incorrectly set to a value that exceeds the validity
period of the default arbitration certificate. As a result, the quorum link fails to be added.
Perform the following operations:
Step 1 Check whether the HyperMetro arbitration certificate on the quorum server is valid.
1. In any directory of the quorum server's operating system, run the qsadmin command to
open the arbitration software.
2. In the CLI of the arbitration software, run the show tls_cert command to check whether
the HyperMetro arbitration certificate is valid.
NOTE
If State is Valid, the HyperMetro arbitration certificate is valid.
– If the HyperMetro arbitration certificate is valid, go to Step 3.
– If the HyperMetro arbitration certificate is invalid, go to Step 2.
Step 2 Check whether the system time of the quorum server is incorrectly set.
Run the date command to check the system time of the quorum server.
l If the system time of the quorum server is correct, go to Step 3.
l If the system time of the quorum server is incorrect, modify the system time and restart
the quorum server. Then add the certificates again. If the quorum link still fails to be
added after the quorum server is restarted, go to Step 3.
Step 3 Check whether the HyperMetro arbitration certificate on the storage array is valid.
1. Log in to OceanStor DeviceManager of the storage array. Choose Settings > Storage
Settings > Value-added Service Settings > Credential Management to go to the
certificate management page.
2. On the certificate management page, check the validity of the HyperMetro arbitration
certificate.
– If the HyperMetro arbitration certificate is valid, go to Step 5.
– If the HyperMetro arbitration certificate is invalid, go to Step 4.
Step 4 Check whether the system time of the storage array is incorrectly set.
Log in to OceanStor DeviceManager of the storage array. Choose Settings > Basic
Information > Device Time to check the system time of the storage array.
l If the system time of the storage array is correct, go to Step 5.
l If the system time of the storage array is incorrect, modify the system time. Then add the
certificates again. If the quorum link still fails to be added after the system time of the
storage array is modified, go to Step 5.
