Purpose

This document is intended to cover the causes of loss of network connectivity to the Administration Interface only of the 7000 series Unified Storage appliance, and to provide solutions for those problems.
The Administration Interface covers both Browser User Interface (BUI) and Command Line Interface (CLI) access to the appliance.

This document is only intended to apply to loss of network access. If the CLI for the Administration Interface is not available via the console run from the Service Processor (SP or ILOM) then the problem is elsewhere. In this situation see <Document 1401282.1> "Sun Storage 7000 Unified Storage System: How to Troubleshoot Unresponsive Administrative Interface" for more information.

Troubleshooting Steps

There are two basic failure modes for network access to the Management Interface. Either both BUI and CLI are unavailable via the network (but the CLI is still available via the console from the SP), or the CLI is accessible via ssh but the BUI is unavailable.

If the CLI is not available at all from the SP console then the problem is not network related.  If this is the case please see <Document 1401282.1> "Sun Storage 7000 Unified Storage System: How to Troubleshoot Unresponsive Administrative Interface (BUI/CLI hang)" for further information.

1. The CLI is available via the console from the SP but there is no access to the BUI

It is likely that the cause of this problem is the absence of a correct network route between the local system and the appliance. To check if there is a fixed route, or a default route set do the following :

Connect to the SP either via ssh to the SP network administration interface, or by serial access to the serial management port on the SP.
Log in as root using the same password as root access to the appliance Mangement Interface.
Start the console

If necessary log in again at the login prompt to access the appliance CLI.

To show the routes currently set

Default routes will show as 0.0.0.0/0.
Manually added routes show as static whereas those automatically added will show as system or dynamic. Only static routes can be removed or edited manually.

There will need to be a route either directly to the local system's network or via a default route, via a gateway that is accessible to both the appliance and local system, and to the correct interface on the appliance that is enabled for admin.
e.g.

For a client to access the Management Interface on the appliance above, it must be on a network from where it can reach the gateway of 10.163.224.1. On the appliance the nge0 interface should have the "Allow Administration" checkbox ticked in the BUI. Check this via the "Configuration > NETWORK" screen and click the "Edit" pencil icon next to the appropriate interface.
Alternatively using the CLI :

should show "admin = true".

If no appropriate route is set then one should be added, either a static route to the local system's network, or a default route via a mutually accessible gateway.
e.g. to add the default route seen above:

For further information on adding routes, see the "Configuration: Network: Routing" section of the online HELP available via the BUI, or the appropriate Administration Guide available from Oracle Unified Storage Systems Documentation.
For best practice recommendations on configuring routes check <Document 1395461.1> "Sun Storage 7000 Unified Storage System: Best Practice Recommendations for Network Configuration".

2. CLI is available via ssh but unable to access BUI

It is possible that the appliance kit http server that acts as the web server for the BUI has faulted or has been prevented from starting.
There may be an alert for this, to check this use the CLI:

If there is a problem simply select it and mark it repaired :

The BUI should now be accessible.
If not, further troubleshooting will need to be carried out by an Oracle TSC engineer, please raise a Service Request to facilitate this.


Check the status of the appliance kit http server from the OS shell:

Check that the system is listening for requests on port 215 on the correct IP address:

If the appliance kit http service is not online and there is no entry for LISTEN on port 215 for the IP address associated with the interface that administration is allowed from then it may be the case that another service on which the svc:/appliance/kit/http:default depends has not started up. Check this by looking at the state of all the services:

If there are other services that have not started up yet it may be that the system was booted via a different milestone and then booted to milestone all using the svcadm command whilst in a shell, which may now stopping some services completing.  This can also happen if you have accessed the system before boot was complete by using the "ESC 9" hidden option to access aktty.
To fix the problem simply exiting the shell you are in should allow the services to complete and the svc:/appliance/kit/http:default service to be started.
If the svc:/appliance/kit/http:default is the only service that is not started then you should just be able to start it up simply by typing:

If after this the svc:/appliance/kit/http:default service still does not start or there are other services not started up please contact the TSC for further assistance. If an SR has not already been raised for the problem, please raise a new one and have it assigned to a member of the NAS team.
