WEARIED!!! NIC card status shows Network Cable unplugged

Good day! All,


We started to use June 2014 HP Support Pack for upgrading BIOS and Firmware for all our HP Physical and Blades Servers..The other day we started to do a update on a Blade BL 460 G6 Server,
As we did so many Firmware updated with NEW SPP it took about 20-25 mints per Server but this one started to act and we waited for like a HOUR and it came back saying Firmware update Failed.

So after further investigating the SPP log found that it go struck updating the NIC card drivers and it just failed moving forward... well hopped on the Server using the KVM and when checked all my NIC's in the Server started to show as Network cable unplugged.

It was very wearied and we tried so many option still with no Luck, then decided to revert back the NIC card drivers , uninstalled every thing and went back to old drivers and still the same issue..


Now after uninstalling the new drivers and reverted to OLD NIC drivers the issue didn't resolve, so we started to check the System logs in Virtual Connect Module.. so to our surprise we saw as below..


Port enc0:iobay1:d4 pause-flood detected and automatically disabled

So we see something disabled and started to google around to see why and what caused the issue.. found a article in HP website similar to this

http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_ba847bafb2a2d782fcbb0710b053ce01=wsrp-navigationalState%3DdocId%253Demr_na-c02623029-6%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.tpst=ba847bafb2a2d782fcbb0710b053ce01&sp4ts.oid=3794423&ac.admitted=1393783592336.876444892.492883150

Still poking around we saw this under ETHERNET,ADVANCE SETTINGS UNDER PORT PROTECTION

At this point we didn't Re-enable Ports but we went back to HP and raised a case.. So they suggested to first upgrade all the NIC's on the blade to current version and then click the Re-enable Ports..

After we upgrade the NIC drivers and then Re-enabled Ports all my NIC's started to connect and every thing was up and running..

Hope this helps someone.. ...
