Goal

 Collecting snapshot over the ILOM LAN-over-USB interconnect instead of via the external SP net mgmt port

Fix

ILOM 3.x provides a mechanism to gather a snapshot which contains diagnostic data useful for support services.  One drawback is that the transport mechanism is over the network, as there is no local USB port on the SP.  This usually means that gathering a snapshot is not possible when there is no network connection to the SP.  ILOM 3.0.12 with Oracle Hardware Management Pack 2.2 provides support for the ilom interconnect, which means there is an internal connection between the host and the SP.  Using this interconnect makes it possible to gather a snapshot even when the SP is not on an external network.

STEPS:

1. Download OHMP 2.2.x and install it on the host.  For more details, see the OHMP Installation Guide:

https://docs.oracle.com/cd/E20451_01/html/E25304/index.html

2. Configure the interconnect on the host if it's not done automatically.  The IP address is automatically assigned using a link-local address:

# ilomconfig list interconnect

If the interconnect isn't enabled:

# ilomconfig enable interconnect

and then confirm:

# ilomconfig list interconnect

Interconnect
============
Type: USB Ethernet
SP Interconnect IP Address: 169.254.182.76
Interface name is net4
Host Interconnect IP Address: 169.254.182.77

3. Connect to the SP over the interconnect using the address from 'ilomconfig list interconnect'

# ssh [email protected]

4. From there run snapshot and set the URI to the IP address of host as shown in the output of 'ilomconfig list interconnect':

-> set /SP/diag/snapshot/ dump_uri=sftp://[email protected]/var/tmp

Note: snapshot supports ftp or sftp. Make sure the host has the specified protocol configured and running.

Now the snapshot requested by Services will be available on the host in the location specified in the dump_uri.
This can easily be changed to write to a USB device on the host if required.
