   After upgrading PowerMaxOS on a PowerMax 2000, the storage team notices that some hosts are experiencing intermittent I/O errors. The upgrade completed successfully, but the team suspects a compatibility issue with the new OS version. What should the team do first to validate the upgrade and identify the cause?

   • ACheck the array's event logs and the host's connectivity status to identify any errors or warnings.
   • BRun a full array backup to protect against data loss before making any changes.
   • CImmediately roll back to the previous PowerMaxOS version to restore normal operations.
   • DReboot all hosts to clear any stale connections.

   A company is upgrading the PowerMaxOS on a PowerMax 2000 that is part of a SRDF/Metro configuration with another array. The storage team has verified that the new OS version is supported for both arrays. The upgrade must be performed without causing a failover or impacting the replication. What should the team do?

   • ADisable SRDF/Metro before the upgrade and re-enable it after both arrays are upgraded.
   • BUpgrade one array at a time, ensuring that the replication remains healthy after each upgrade.
   • CUpgrade the secondary array first, then the primary, to maintain data protection.
   • DUpgrade both arrays simultaneously to avoid any replication mismatch.
