6.5 What Can I Do If the Remote Connection Fails to Be
Created with the TOE Interface Module
Question
What can I do if the remote connection fails to be created with the TOE interface module?
Answer
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.
NOTE
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:
1. 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 confirm with the system log.
2. 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.
a. Enter minisystem mode, run the tcp_recycle_switch.sh off command.
b. Add the remote device and establish the replication link.
c. Enter minisystem mode, run the tcp_recycle_switch.sh on command.
6.6 How Can I Use OVA Templates to Quickly Deploy
Virtual Quorum Servers?
When a quorum server virtual machine (VM) becomes faulty, you can use an OVA template
to deploy it again quickly.
Exporting an OVA Template
After a quorum server VM has been deployed and works properly with storage systems, you
can export an OVA template of this VM for quick deployment once the VM fails.
