In order to upgrade the Bios and hardware firmware on Cisco C series series we need to have the following:
- To know the c-series product model # you looking to upgrade the firmware on
- Download the latest iso image with server firmware.
How do we achieve it:
- download HUU ( Host Upgrade Utility) ISO image to your workstation
- login to C-IMC ( Cisco Integrated Management Controller) via a browser
- open up Java based virtual KVM
- attach the iso image from your workstation
- reboot server
- Press F6 during the boot
- boot from virtual DVD
- run the pre-upgrade check
- upgrade bios and firmware on raid controller, mlom, NIC cards, and etc reboot the system
Server Product model and version can easily be identified under “Server Summary” when you login to the server via CIMC.
You will need to have an account with Cisco to download the server Continue reading “Upgrading firmware and bios on Cisco’s C220/C240 series servers”
I have not seen any special feature improvements in 5.5 over 5.1 that would have benefited our environment, and as with any other major new releases was patiently waiting for VMware to come out with Update 1 for vSphere 6. Originally I had the SSO, VMware Update Manager, and vCenter each running on its own server. Databases for SSO and vCenter are separated to a standalone SQL 2008 R2 server. I ended up combining the VUM and vCenter on one single server, and upgrading the SSO to PSC (Platform Services Controller) and kept it separate, in case if we go with 2nd vCenter in the future.
Upgrading vCenter from 5.1.x to 6.0 is quite straight forward process, mount the vCenter 6 VMware-VIMSetup iso image to the vCenter server, and run the installer. It will recognize that there is a previous version installed and offer you to upgrade it.But first, make a backup of working production servers, before the upgrade. Shutdown the VMs, and copy the SSO and vCenter vmdks to a separate folder – in case if snapshots decide to take a break from work. Take the SSO, vCenter snapshots, and of course backup the SQL databases, if you have them running separately.
Don’t despair, if you receive the below error during vCenter upgrade: Continue reading “Error while upgrading from VMware vCenter 5.1 to vCenter 6.0”
