If you are having problems attaching to the Ethernet hosts, your problem might be related
to the network, the
system, or the host.
Note: The system and Host IP should be on the same VLAN. Host and system nodes should not have same
subnet on different VLANs. iSER host attach or clustering is disabled on 100g
ports and iSCSI host attach performance is restricted to 25g ports.
For network problems, you can attempt any of the following
actions:
- Test your connectivity between the host and
system ports.
- Try to ping the system from the host.
- Ask the Ethernet network administrator to check the firewall and router settings.
- Check that the subnet mask and gateway are correct for the
system host configuration.
Using the management GUI for system problems,
you can attempt any of the following actions:
- View the configured node port IP addresses.
- View the list of volumes that are mapped to a host to ensure that the volume host mappings are
correct.
- Verify that the volume is online.
For problems with iSCSI-attached hosts, you can attempt any of the following actions:
- Verify that the host qualified name (IQN) is correctly configured.
- Use operating system utilities (such as Windows device
manager) to verify that the device driver is installed, loaded, and operating correctly.
- If you configured the VLAN, check that its settings are correct. Ensure that Host Ethernet port,
system Ethernet ports IP address, and Switch port are on the same
VLAN ID. Ensure
that on each VLAN, a different subnet is used. Configuring the same subnet on different VLAN
IDs can cause network connectivity problems.
- For iSCSI discovery or login failure, verify that the target IP and
host object are part of the same portset.
- For missing target IP in the discovery records, verify that the
target IP and the host object are part of the same portset.
