Creating PS to SC Replication Might Generate Mapping Server Alerts Replicating from a PS array to a Storage Center volume succeeds, but generates a mapping server alert on the Storage Center regarding connectivity. You can ignore these mapping server alerts. Cross-Replication From a Storage Center to a PS Group Replication Fails Due to Insufficient Space Delegated space must be at least 1GB greater than the reserved space allocated for all volumes. The quota checker looks to see if enough space is available before starting the first replica. If the delegated space does not have enough free space, the replica fails with an error similar to insufficient quota available. Replica Creation Limit Cross-platform replication supports the following when created using an SC as the primary and a PS as the destination: • 4,096 replicas created with SC4020 as the primary • 10,000 replicas created with SC8000 as the primary Do Not Create a Storage Center Replication Volume If a Storage Center Is Not a Replication Partner If you create a Storage Center volume that only has a PS group as the replication partner, the following error is returned: There are no Storage Arrays available to be the destination of a replication. Status of Replication Is Incorrect When replicating from a PS Series array to a Storage Center, if the remote partner (Storage Center) is down, the status in Dell Storage Manager does not get updated until the next time replication is triggered from the PS Series array. When Using Cross-Platform Replication, PS Group Manager Takes a Long Time to Reflect the Replica Status During a cross-platform replication operation, if the Storage Center is powered down, the PS Group Manager can take up to 20 minutes to reflect the replica status as Partner Down. Discrepancy In Replica Count After Performing Promote and Failback to Primary While performing a PS to SC replication, during the DR activation (failover) and failback, Group Manager displays the replica count incorrectly. This replica count issue does not impact the replication process. Replica Count Is Incorrect After the Partner (Storage Center) Is Powered On Creating a replica for a volume while the partner (a Storage Center that already contains replicas) is down results in an incorrect replica count in Group Manager when the partner is brought back up. Dell Storage Manager shows the correct replica count. Hardware Replacing an 8-TB Drive With a 4-TB Drive Is Not Supported. On a PS6610 member, you can upgrade a disk from 4 TB to 8 TB, but downgrading an 8 TB disk to 4 TB is not supported. When PS4210 or PS6210 Arrays Are Halted, the ERR LEDs for Both Controllers Are On When a PS4210 or PS6210 array is halted using the halt command, the controllers and battery backup units (BBU) go into ship mode, but the ERR LEDs on both control modules remain ON (red light). On a Controller Failover, the Following Erroneous Message Might Appear On the Console or Group Manager During a controller failover, fan failure messages similar to the following might be falsely reported on the console or Group Manager: Multiple fans are operating outside of acceptable speed ranges. This condition occurs rarely, and when it does, the fans go to a higher speed and then come back to the normal speed in approximately 10 to 15 seconds. Networking Member Cannot Detect IPV6 Group Address Automatically If the Group Name Is Numeric If you create a group with a numeric name, you must also provide the IPv6 well-known address (WKA) to join the group. Use TLS with OpenLDAP Port 389 Use TLS with OpenLDAP with the default port of 389 and not with port number 636 as mentioned on the OpenLDAP faq webpage. Replication Confusing Error On Replication Test Partnership Page While using replication, on the test partnership page if you test an IPv4 partner on a group configured for IPv6, the following error is displayed: Internal Error, could not complete tests. The intended error should be: Unable to communicate because both sides of the replication partnership must use the same IP version. 10 Dell EqualLogic PS Series Storage Arrays Firmware Version 10.0.3 Release Notes
