Server (HP) not reachable on network “Port was disabled because a pause flood was detected” .

Host was not reachable on network. When checked on ILO server is up and running. When I try to ping the server its unresponsive.Host is a blade server, hence suspected an issue with the network module. Therefore, connected virtual connect. Found one of the virtual connect module was degraded. When analysed the HP Virtual connect found an error message stating “Port was disabled because a pause flood was detected”

Further to this when validated the server port assigned to the bay1/bay2 found the status “Not Linked/Pause Flood Detected”. It confirms the issue was caused by pause Flood. In some cases, a flex-10 port can enter into disabled state due to the triggering of “pause-flood”, or network-loop. You can confirm the same port status using Virtual Connect Manager CLI. Connect to Virtual connect using SSH and Execute the below command:

Show port-protect

This would show the blade server that’s in impact. To fix the issue, please execute the below command:

reset port-protect

Verify the port status again using the command “show port-protect” and ensure no port’s protect types are reported as “Pause Flood”.
Another action plan would be to update the Drivers and Firmwares.

You can also disable is using the command listed below
set port-protect pauseFlood=Disabled

How to generate offline logs and ADU diagnostics report for HP Servers.

Most often, when a case is raised with HP support team, we are asked to generate logs and send it to HP. Recently, I had an issue with an ESX server and suspecting a faulty controller. HP asked us to generate and send offline logs and ADU diagnostics report.

Generating requested logs can be achieved using the Smart CD. However, how to save and move files to send it to the HP Team was bit challenging.

Initially tried mounting a a folder from the ILO console and to save the logs in to the folder recently mounted. Bad luck that did not work.

Later, thought the concept of virtual floppy to achieve the task.

Last year we created a floppy image to insert HDD drivers during Windows 2000 installation

Create floppy image to insert drivers during 2000 OS deployment.

The same tool BFI (Build Floppy Image) was very handy again today. You would be able to download the file from here -> BFI’s home page.

Reboot and boot the server using Smart CD.

1. Create an empty floppy image using the below syntax

Syntax: bfi -f=[Location to store image with image name]

Ex: bfi -f=c:\temp\floppyimg.img

2. Mount the same floppy image using the ILO connected to the server.

Follow below steps to generate the logs

A. Survey Report.
1. Boot the server with Smart Start CD/ Bootable pen drive smart start
2. Select language – English.
3. Select Maintain server.
4. Select Diagnose Server.
5. In survey Tab
Select Category >> ALL.
Select View Level >> Advanced.
And save the report.

B. Offline Test Report (3 Loop).
1. Boot the server with Smart Start CD/ Bootable pen drive smart start
2. Select language – English.
3. Select Maintain server.
4. Select Diagnose Server.
5. In Test Tab
Test mode à Unattended.
Number of loops à 3.
Devices à All.
Select Complete test and click the begin test option and save the report after completing the test.

Note : Please uncheck the Storage / hard disk in test

C. Offline IML logs.
1. Boot the server with Smart Start CD/ Bootable pen drive smart start
2. Select language – English.
3. Select Maintain server.
4. Select Diagnose Server.
5. In Log tab
Select Integrated Management Log and save the report.

D. Offline ADU report:
1. Boot the server with Smart Start CD/ Bootable pen drive smart start
2. Select language – English.
3. Select Maintain server.
4. Diagnose array Option.
5. Save the report.

You may now save the reports to the virtual floppy and once done unmount and map it to any other working server ILO. You can now login to the server and easily copy the contents from A: to any destination 🙂

 

Thanks.

Recently, we upgraded firmware on all our blade enclosures and servers. This time we got stuck with the Citrix servers. We were informed that the Citrix applications are not working after the recent updates.

How to reset blade slot in HP C7000?

What you can do is to SSH into the chassis via the OA address/ip and then, issue the following command to reset the specific blade. Just insert the bay number of the blade that you would need to.

reset server <bay #>

This command is almost equivalent to completely removing the server and reinserting back. When you issue this command, ILO will also get disrupted for few seconds.
