Save wasting your time!
I have Nexus 5.2 installed and have found the host will not upgrade to ESXi5.1 due to incompatible VIB's.
Hope this gets fixed soon, I dont fancy creating a custom ESXi installer.
It can be done, but not the easy way with Update Manager.
The downloaded patch from Cisco (updated VEM) will not install on VMWare prior to 5.1, so you have to do a fresh install of the server and then apply the Cisco patch..
The Host will be "out of sync" in the Nexus VMware config, so you have to remove it from the distributed switct and then add it to the distributed switch again...
After that you'll have a 5.1 host with nexus running fine.
Hopefully there will be a 5.1 custom ISO made that have the latest Cisco VEM incorporated... It would me much easier just upgrading all host via Update Manager :-)
This does not work!
Have tried a few methods, all with the same result as per below:-
tmp # esxcli software vib install -v /tmp/cross_cisco-vem-v144-184.108.40.206.5.2.0-3.
VIB Cisco_bootbank_cisco-vem-v144-esx_220.127.116.11.5.2.0-3.0.1 requires esx-base << 5.1.0, but the requirement cannot be satisfied within the ImageProfile.
Please refer to the log file for more details.
I also get the same error trying the update the ESXi5.1 Image with the NExus 5.2 VIB using PowerCLI
Basically, Nexus 5.2 appears to have dependency on ESXi5.0
Please can Cisco verify this?
OK after a little digging the VEM is in the bundle from Cisco.
If you download the 1.5.2 bundle from cisco.com (even if you have it from a previous download, redownload the bundle) in the VEM directory there is a file cross_cisco-vem-v144-18.104.22.168.5.2.0-3.1.2.vib.This is the vib you need to use for ESXi5.1
When 1.5.2 came out we had hooks for it to work with ESXi5.1 but we were not allowed to provide the 5.1 VEM module in the bundle until VMware officially shipped ESXi 5.1. So you need to redownload the bundle and pull the VEM module out of the zip file.
Ok so there is no way to go from 5.0 with 5.2 1000v to 5.1 ? I have to remove the 1000v VEM first and then upgrade to 5.1 and reinstall VEM ? This seems backwards, is that the only way ?
After much searching around I found at http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_2_1_s_v_1_5_2/install_upgrade/vsm_vem/guide/b_Installation_and_Upgrade_Release_4_2_1SV1_5_2_appendix_0100.html#task_177902672B004D0F93380CF04AF2ED45
thatin 4.2.1SV1.5.2 there supposed to be a 3.0.2 VIB, but there isnt. There is only 3.0.1 VIB.
What exactly are we supposed to do ?
Just want to check if there is still an issue with an upgrade from vsphere 5.0 with 1000v 5.2 to vpshere 5.1
Do I still need to remove the VEM , upgrade to 5.1, and reinstall the VEM? Thanks.
If you are upgrading to 5.1 you will need to install a VEM module that is compatibile with 5.1. The VEM module for 5.0 is not compatibile with 5.1.
You can either build the upgrade image with the 5.1 VEM in it or you can uninstall the host from the n1kv, upgrade to 5.1, and then reinstall the host to the n1kv.
It's not hard to build an upgrade image and add the 5.1 VEM module.
