© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 9 Operating System  Check the support matrix before installing the OS on the blade  Install / keep the drivers (Eth / FC) updated as per the matrix  Few important things to check: –Is the blade running the certified OS and OS version? –Are there any special needs for that OS? E.g. VMWare – OEM Image –Are the drivers at the OS level updated and current?  Answer: –UCS S/W and H/W matrix –http://www.cisco.com/web/techdoc/ucs/interoperability/matrix/matrix.html –http://www.cisco.com/en/US/products/ps10477/prod_technical_reference_list.ht ml

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 15 Agenda  C series firmware upgrade  Pre-requisites  Firmware ISO location and downloading  Upgrade process  B series firmware upgrade  Pre-requisites  Firmware bundles and downloading  Upgrade process  Additions / Modifications from version 2.1

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 17 Things to consider  Release Notes will cover gotchas and concerns in the upgrade process  Upgrades from one version back will always work  Check release notes about prior versions –If customer is really far behind it might require two upgrades to get to current code  Schedule an maintenance window –CIMC and server will reboot during upgrade

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 28 Things to consider  Release Notes will cover gotchas and concerns in the upgrade process  Upgrades from one version back will always work  Check release notes about prior versions –If customer is running a very old version, it might require two upgrades to get to current code  Schedule an maintenance window –FI and IOM will reboot during upgrade –Make sure network and storage fabric are redundant  Highly recommended to backup UCSM configuration

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 29 Be patient  Upgrade process is not quick  Sometimes bugs will result in the first release after FCS  Expect a maintenance release shortly after FCS  Follow the upgrade procedure for each version –The procedure is not always the same from one version to another.

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 30 Downgrading  Sometimes there might be data loss  Might have to erase config to downgrade –Database changes in new versions cannot always be back ported

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 32 Bundles  Prior to 1.4 there was only all inclusive bundle  Now there are multiple bundles –Infra-bundle – contains code for FI, IOM, and UCSM –B-series bundle – contains BIOS and blade specific code –C-series bundle – contains BIOS and rack server specific code

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 35 Bundles  Bundles are downloaded from the “Download Tasks” tab  Downloads can be through desktop or using ftp/scp/sftp/tftp

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 39 Upgrade Process  Again always consult release notes  Upgrade through GUI is easiest  General Process is Backup UCS Config (Full & All Config) Download code Update components Activate components in order of (Check RN cause order can change) Interface cards – Set Startup Only CIMC IOM – Set Startup Only UCSM FI

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 40 Updating Components  Update means copy new code to backup location of all UCSM components  Simply stages the new code  Can update all components at once

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 41 Updating Components  Time to update will vary based on component  IOMs take a long time. Up to 5 minutes  If any component has issues check FSM for that component  Update process does not work on FI  Once everything is in “Ready” state you can move to Activate

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 42 Activate Components  In this process you activate the code that you copied  Some code is activated but set to “activate on next reboot”  Understand that in this stage you can create outages  Activate “leaves of the tree” first –BU uses this term to mean that order should be Interface card = leaf CIMC = twig IOM = branch UCSM = trunk FI = root

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 43 Activate Blade Components  Recommended Method is to use Policies –Host Firmware Policy to apply latest BIOS, Board Controller, Adapters, etc.

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 44 Activate Interface cards  Set to “Set to startup version only”  If you uncheck above box it will cause a blade reboot!!!

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 48 Activate Fabric Interconnect  Recommended to activate one FI at a time  A complete outage will not occur  Fail one fabric  Wait for all Network and FC traffic failover to second Fabric  Highly recommended to have an outage window  Biggest risk is SAN storage  FI will upgrade and reboot  Part of the process is to reboot connected IOM as well  Can take up to 10-15 minutes for FI and all IOM to come back online  If any failure during first FI upgrade STOP! Do not attempt to upgrade second FI

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 50 Activate Fabric Interconnect  Choose correct Kernel and System Version  FI will take a few minutes and then reboot  IOMs will get updated as well

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 52 Upgrade Primary Fabric Interconnect  Upgrade the Primary FI now using same process  UCSM will failover to subordinate FI  Will need to log back in to UCSM

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 53 Problems  Biggest concern is a failed IOM upgrade –There is no way in field to upgrade an IOM manually –RMA the failed IOM –Can attempt a physical reseat of IOM  Failed FI upgrade can be recovered –Similar to N5K will require access to console and tftp server to boot from –Refer to FI recovery method

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 55 Host firmware  Highly recommended that Blade BIOS match running UCSM system  Best way to upgrade BIOS is through Host Firmware Policy  Create policy in UCSM  Apply policy to SP  Will reboot the blade so need outage window

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 57 Host Firmware Policy  Note that Firmware Policy can include –Adapters, BIOS, Board Controller, FC Adapters, HBA Option ROM and Storage Controller  Note how Adapters and FC adapters can be part of a policy –If adapters are part of policy then they can only be changed as part of firmware policy  Recommended to upgrade BIOS and Storage Controller at a minimum  Board adapter rarely changes and is specific to B230 and B440

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 58 Set BIOS versions  Best to choose all hardware  Set BIOS to the latest in the pull down for each blade/server  Latest BIOS version will be different for some servers

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 62 Firmware Auto-Install  Firmware Auto-Install implements package version based upgrades for both UCS Infrastructure components and Server components  Firmware Auto-Install can not be used to upgrade Management Extensions and Capability Catalog. These are simple occasional updates in UCSM and hence left under user control.  It is a two step process - “Install Infrastructure Firmware” and “Install Server Firmware”.  It is recommended to run “Install Infrastructure Firmware” first and then “Install Server Firmware”  All existing firmware upgrade mechanisms are retained. For users who do not want to use Auto-Install, they can continue to use existing documented way of doing firmware upgrades.

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 63 Install Infrastructure Firmware (contd)  This is the sequence followed by “Install Infrastructure Firmware” 1. Upgrade UCSM 2. Update backup image of all IOMs 3. Activate all IOMs with setstartup option 4. Activate secondary Fabric Interconnect 5. Wait for User Acknowledgement*** 6. Activate primary Fabric Interconnect

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 65 Install Infrastructure Firmware - Cancelling A scheduled “Install Infra” operation can be cancelled But an “Install Infra” operation which is already “In Progress” can not be cancelled. Both GUI and CLI options are available for cancelling.

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 66 Install Infrastructure Firmware – User Acknowledgement for primary FI “Install Infra” expects an explicit permission from user to start firmware upgrade on primary Fabric Interconnect. This is necessary to protect the data path for servers. As part of “Install Infra”, secondary FI’s firmware is upgraded first. Secondary FI reboots as part of firmware activation. After secondary FI comes online, users are expected to check if the data path is ready for a reboot of primary FI When users have ensured that the data path is ready, they can acknowledge reboot of primary FI.

© 2011 Cisco and/or its affiliates. All rights reserved.Cisco Public BRKCOM-3001 68 Install Server Firmware Install-Server offers a way to update multiple host firmware packages using package versions. It provides the list of Service Profiles that will be affected when a host firmware package is modified. Multiple SPs can use the same host firmware package. It also provides a final summary of physical servers that will be rebooted for the set of host firmware packages that are getting modified. Only GUI is available for "Install Server Firmware". No CLI.
