Both EVA4400 embedded san switch port no light, host port status is Link to switch failed

louisji2008 — Mon, 13 Nov 2017 14:26:33 GMT

Command View shows both controllers are good, except all the host ports status are "Link to switch failed."

The LED status of all the FC ports on the both embedded san switch is: amber and green are always on. And no light in the port comes out.

The mgmt port is not accessible via 10.77.77.77, assumed someone has changed it. Tommorrow I will take a console cable to take a look at it.

Has anyone see this issue before?

Update on issue:

Engineer came and replaced memory dimms for both controllers for the embedded san switch.

The memory dimms for the san switches are similar to notebook memory, and not the same as the controller memory dimms which are larger.

EVA and switch back to normal now.

This issue occurred after a power outage.

Does any one know what is the spare part number for the EVA4400 embedded san switch memory DIMM?

Hello,

1GB Cache DIMM modules 635205-001

You would need two of them.

Hello,

There are two different issues mentioned in this post and replies.

1. The controller will not boot and fail with boot error code as soon as it starts to boot.

This is fixed by replacing the two memory dimms of the controller.

2. The controller boots up but under both host ports for each controller it says link to switch failed.

This is a switch failure and both controllers will need to be replaced 1 at a time. Depending on the code you are running you would need to be very carefull how the controllers are replaced to keep from updating the formware of the array and possible losing access to the data.

Also if you are trying to get into the Management Module hare are the instructions.

You can find the below information in the

HP 4400 Enterprise Virtual Array Installation Guide

Connecting to the management module
You can connect to the management module through a public or a private network.
NOTE: To aggregate additional HP Command View servers into a SPoG (Single Pane of Glass)
when the servers reside on a different IP network from the SPoG web server, some additional
configuration settings may be needed. To configure the system if the HP Command View servers
reside on a different network and you would like them visible in the SPoG, see Discovery URI under
Discovery configuration settings in the HP Management Integration Framework Administrator Guide.
If you use a laptop to connect to the management module, configure the laptop to have an address
in the same IP range as the management module (for example 192.168.0.2, with a subnet mask of 255.255.255.0).

Connecting through a public network
1. Initialize the EVA4400 storage system, using HP P6000 SmartStart or HP P6000 Command
View.
2. If it is currently connected, disconnect the public network LAN cable from the back of the
management module in the controller enclosure.
3. Press and hold the recessed Reset button (3, Figure 18 (page 25)) for 4 to 5 seconds. If you
are running HP Command View EVA 9.3 or later, the green LED on the management module
(1, Figure 18 (page 25)) blinks to indicate the configuration reset has started. The reset may
take up to 2 minutes to complete. When the reset is completed, the green LED turns solid. This

sets IP addresses of 192.168.0.1/24 (IPv4) and fd50:f2eb:a8a::7/48 (IPv6). If you are
running a version earlier than HP Command View EVA 9.3 on the management module, the
amber LED will flash momentarily when the reset is completed.
IMPORTANT: At initial setup, you cannot browse to the HP P6000 Control Panel until you
perform this step.
4. Do one of the following:
• Temporarily connect a LAN cable from a private network to the management module.
• Temporarily connect a laptop computer to the management module using a LAN patch
cable.
5. Browse to https://192.168.0.1:2373 or https://[fd50:f2eb:a8a::7]:2373/and
log in as an HP administrator. HP recommends that you either change or delete the default
IPv4 or IPv6 addresses to avoid duplicate address detection issues on your network. The default
user name is admin. No password is required. The HP P6000 control panel GUI appears.
IMPORTANT: The HP P6000 Control Panel previously used port 2372 but now uses 2373.
If you change the password for the administrator or user account for the HP P6000 Control
Panel, be sure to record the new passwords since they cannot be cleared without resetting
the management module. HP recommends that you change the default passwords.
6. Select Administrator Options > Configure Network Options.
7. Enter an IP address and other network settings that apply.
NOTE: The management module firmware reserves IP addresses for internal communications.
If you are using HP Command View EVA 9.2 or earlier, the reserved IP addresses are 10.0.0.1
through 10.0.0.3. Later versions of the management module firmware will also use these
addresses if the array has older controller firmware loaded. The latest versions of controller
and management module firmware, however, use the reserved IP address range from
10.253.251.230 through 10.253.251.249. The management module cannot be configured
to use these addresses, nor can it communicate with external systems that fall within the reserved
address range (for example, web client, router, DNS server, and so on).
8. Click Save Changes.
The new IP address is stored and remains in effect, even when the storage system is later shut
down or restarted. The IP address changes immediately, causing you to lose connectivity to
the HP P6000 Control Panel.
IMPORTANT: The new IP address will be lost if the storage system is later uninitialized or
the management module is reset.
9. Remove the LAN cable connecting to the private network and reconnect the cable to the public
network.
10. From a computer on the public network, browse to https://newly configured ip
address:2373 and log in. The HP P6000 control panel GUI appears.
