When a remote device whose type is Replication is added, or the iSCSI link is added to the remote device, if error code 1073804034 occurs or the connection fails to be created, the cause may be that the storage system uses the TOE interface module to connect. When the local storage system uses the TOE interface module to connect to the remote storage system, since protocols of the TOE and non-TOE interface modules process data in different ways, the two systems may have different connection methods, causing connection failure.
If the remote storage system uses the TOE interface module but the local storage system uses non-TOE interface module, the above problem does not occur.
Perform the following operations to locate and handle the problem:
On a network where the TOE interface module connects the non-TOE interface module, if the link fails to be created on the storage system where the TOE interface module resides, and a communication exception error is returned, then the problem is what has been described above. If you need to further confirm the problem, contact technical support engineers to check the system log.
After the confirmation, handle the problem with any of the following methods.
Method 1: Select the non-TOE interface module as the end for starting the connection. The TOE interface module is the receiving end of the connection. Establish the connection oppositely. This method helps establish the link.
Method 2: On the storage system where the non-TOE interface module resides, run the tcp_recycle_switch.sh command to disable the function of quickly recycling TIME_WAIT socket in the TCP connection. After the link is established, enable the function.
Enter minisystem mode, run the tcp_recycle_switch.sh off command.
Add the remote device and establish the replication link.
Enter minisystem mode, run the tcp_recycle_switch.sh on command.
