Hana database server cannot reach CVO

HANA Database servers indicates that there is an issue reaching ONTAP storage

The issue was identified as an expired Kerberos ticket on the client side
Kerberos tickets have a default lifespan of 10 hours, after which they need to be renewed
The client did not renew the ticket in time, leading to authentication failures and NFS connectivity issues

If the issue is observed again, collect packet traces and work with a NAS resource to identify potential Kerberos timeouts

These are additional options that can be used to help mitigate the risk of the Kerberos ticket expiring:

Ensure that the client system renews Kerberos tickets before expiration:
- This can be achieved by configuring automatic ticket renewal on the client side
  - Use the following commands to verify Kerberos configuration:
    - ::> kerberos interface show
    - ::> kerberos realm show
Increase Kerberos ticket lifetime:
- Adjust the Kerberos ticket lifetime settings to extend beyond the default 10 hours if feasible for your environment
Monitor and capture logs:
- Implement proactive monitoring to detect Kerberos ticket expiration issues in real-time
- Enable packet tracing to capture network traffic during future occurrences for deeper analysis

These are two options that can be used to attempt to quickly resolve the connection:

Purge existing Kerberos tickets and acquire new ones using the following steps:
- Run `klist purge` on the client system
- Log out and log back into the system, or reboot the client machine
Temporarily disable Kerberos authentication if business continuity is critical, and switch to an alternative authentication method

Note: This has was not used for this case, because the issue resolved itself
