HP ILO - DL160 G6 - Missing Hardware Inventory & Monitoring Sensors

 

Intro:

Missing Hardware Inventory & Monitoring Sensors on the ILO page after an ILO firmware update? If you just upgraded the BMC ILO firmware and didn't boot the machine then the Hardware Inventory & Monitoring Sensors page will be blank.

• You'll also notice that under the ILO Summary page, the description will read as:

Description:

Proliant generic G6

instead of:

Description:

DL160 G6

Fix:

• To get this back simply boot the system.

• Look for the line..."New Generic BMC Detected, Pre-Install a BMC SDRR/CFG". It will automatically update the BMC and the description on the summary page will change and the Monitoring Sensors page will come back.

HP ILO - com.serverengines.rdr.EndOfStream: EndOfStream

 

Intro:

Every so often this bug will arise when trying to connect to the KVM implementation on HP ILO servers. However as of 2017, all major modern browsers have dropped support for Java applets, which relied on the Java NPAPI (Netscape Plugin Application Programming Interface) plugin. Chrome dropped it in 2015 and FireFox in 2017.

*As long as 32-bit Java is installed you can run the standalone applet under Windows 10/11.

Fix:

    1. Point your browser to http://<IP_ADDRESS>/M2.JAR

• Make sure m2.jar is capitalized or it won't download the file.

    2. Run the M2.JAR file and input your IP, username, and password.

• As long as you have a 32-bit Java SE Runtime Environment that's either v202 or below, this will work.

HPE - Enable Jumbo Frames - 3500yl EDGE Switch

Info:

I usually enable jumbo frames on all my switches as part of tuning network performance. This particular setting is beneficial for large transfers, ie in the gigabyte or terabyte range. The endpoints must be able to support jumbo frames or this will not work. If you have virtual switches on the network be sure to configure them for jumbo frames as well.

Start Here:

Login to your HPE switch. Type what is in bold only. Enter is pressed after each command. (This should work with other HPE switches however I do not have an exhaustive list. Consult your manual here if you run into any syntax issues).

After login type:

    <switch># config

You are now in config mode. (After you type this command, in the rightmost column you'll see whether or not Jumbo Frames are enabled on said VLAN:

    <switch>(config)# show vlans

Do not type the < or > character; you just need to insert the VLAN ID# below:

    <switch>(config)# vlan <ID#> jumbo

Check if the setting applied successfully:

    <switch>(config)# show vlans

Save your changes to the switch:

    <switch>(config)# write memory

Logout from the switch.

Next Step:

Be sure to configure any devices in between this switch and including endpoint to support jumbo frames.

TIP:

If you'd like to disable Jumbo Frames for testing, type only what is in bold below while at the CLI:

    <switch>(config)# show vlans

    <switch>(config)# no vlan <ID#> jumbo

    <switch>(config)# show vlans

    <switch>(config)# write memory

The commands above will do the following:

1. You will see the VLAN Jumbo table.
2. You'll turn off jumbo packets for whichever VLAN ID# you type in.
3. You'll verify the setting changed.
4. Finally you'll write the changes to memory.
