I decided to update my ESXi host to 5.1 just cause it was time to catch up on updates.

Using esxcli to Perform the Update

I was currently on 5.0U2:

~ # vmware -lv
VMware ESXi 5.0.0 build-914586
VMware ESXi 5.0.0 Update 2

Reading over the vSphere Upgrade Guide for vSphere 5.1, I saw that esxcli was a viable option for the update. From the guide, here is a table of the upgrade paths:

51 upgrade methp1 Updating ESXi 5.0U2 to ESXi 5.1U1

51 upgrade methp2 Updating ESXi 5.0U2 to ESXi 5.1U1

There is also VMware KB 2032757 which summarizes the upgrade guide into a KB. The KB is really helpful except it has a conflicting statement. The KB has a table that says esxcli cannot be used when going from 5.0 to 5.1. Here is the table:

wrong table from Kb Updating ESXi 5.0U2 to ESXi 5.1U1

Under the Update a Host with Image Profiles section of the Upgrade Guide, I saw the following:

You can update a host with image profiles stored in a software depot that is accessible through a URL or in an offline ZIP depot.

Update the existing image profile to include the VIBs or install new VIBs. esxcli update 51 guide Updating ESXi 5.0U2 to ESXi 5.1U1

I did some research and I came across A Pretty Cool Method of Upgrading to ESXi 5.1. In that post it describes the process on how to update to 5.1 with esxcli and download the upgrade from a VMware hosted VUM depot. In summary here are the steps:

  1. Open firewall to allow outbound HTTP traffic: esxcli network firewall ruleset set -e true -r httpClient
  2. Check available “profiles” to be applied: esxcli software sources profile list -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml
  3. Apply one of the profiles, in the below example it uses the 5.1 profile: esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.1.0-799733-standard

In the example from the above post, the blogger goes from 5.0u1 to 5.1 using esxcli (not sure why the VMware KB states otherwise).

Doing the Update

I checked out the download for 5.1 and I saw the following:

51 offline bundle 1024x113 Updating ESXi 5.0U2 to ESXi 5.1U1

The bundle was ~300MB, rather than downloading that using the ESXi host, I decided to first download it to my local desktop and then copy it to the host (just in case the update fails, I wouldn’t want to download that again… plus I can save it in my ISOs repository for later use as well). Then uploading the file to my datastore:

$ scp VMware-ESXi-5.1.0-799733-depot.zip esx:/vmfs/volumes/datastore1/.
VMware-ESXi-5.1.0-799733-depot.zip            100%  298MB  16.5MB/s   00:18

Checking out the profiles:

~ # esxcli software sources profile list --depot=/vmfs/volumes/datastore1/VMware-ESXi-5.1.0-799733-depot.zip
Name                        Vendor        Acceptance Level
--------------------------  ------------  ----------------
ESXi-5.1.0-799733-no-tools  VMware, Inc.  PartnerSupported
ESXi-5.1.0-799733-standard  VMware, Inc.  PartnerSupported

This actually matched the output from the above blog as well (but in the blog it was showing the profiles stored on the hosted VMware VUM depot).

Let’s put the host into maintenance mode:

~ # vim-cmd hostsvc/maintenance_mode_enter

And now for the update:

~ # esxcli software profile update -d /vmfs/volumes/datastore1/VMware-ESXi-5.1.0-799733-depot.zip -p ESXi-5.1.0-799733-standard
Update Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Reboot Required: true
   VIBs Installed: VMware_bootbank_ata-pata-amd_0.3.10-3vmw.510.0.0.799733, VMware_bootbank_ata-pata-atiixp_0.4.6-4vmw.510.0.0.799733,...
   VIBs Removed: VMware_bootbank_ata-pata-amd_0.3.10-3vmw.500.0.0.469512, VMware_bootbank_ata-pata-atiixp_0.4.6-3vmw.500.0.0.469512, ....
   VIBs Skipped: VMware_bootbank_net-tg3_3.110h.v50.4-4vmw.510.0.0.799733

I then restarted the host to finish the update.

Fixing Post Update Issues

At first the update looked really good, the host rebooted and the regular ESXi management logon window didn’t show any errors. I tried connecting to the host with a vSphere Client but it would fail. Luckily I had SSH enabled and I was able to check out the logs. After some investigation, I saw that hostd would not start up. I would actually see a backtrace in the hostd logs:

Checking out the VMware Communities, I ran into this discussion. The person from that discussion ran into a similar issue and fixed the issue by resetting the configurations. So going through the IPMI interface, I tried the same thing:

reset configuration Updating ESXi 5.0U2 to ESXi 5.1U1

After the reset, it started the reboot of the host:

settings reset g Updating ESXi 5.0U2 to ESXi 5.1U1

After the host rebooted, hostd started up fine without issues. I must’ve made some customization that caused hostd to fail. I reconnected to the host and recreated: my vSwitch, iSCSI, and networking settings (it actually didn’t take that long, but if you had a lot of settings be careful).

Update from 5.1 to 5.1U1

While I was in the updating mood, I decided to update to the latest 5.1 version. I want back to the myvmware web page and saw the offline bundle:

51 u1 offline bundle 1024x116 Updating ESXi 5.0U2 to ESXi 5.1U1

This was just a regular offline bundle, so after I copied the file to the ESXi host, I ran the following to apply the update:

~ # esxcli software vib install -d /vmfs/volumes/datastore1/update-from-esxi5.1-5.1_update01.zip
Installation Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Reboot Required: true
   VIBs Installed: VMware_bootbank_esx-base_5.1.0-1.12.1065491, VMware_bootbank_esx-xserver_5.1.0-0.11.1063671, ..
   VIBs Removed: VMware_bootbank_esx-base_5.1.0-0.0.799733, VMware_bootbank_esx-xserver_5.1.0-0.0.799733,
   VIBs Skipped: VMware_bootbank_ata-pata-amd_0.3.10-3vmw.510.0.0.799733, ...

Then to reboot the host, I ran the following:

~ # esxcli system maintenanceMode set -e true
~ # esxcli system shutdown reboot -r update

I already had all the VMs off, so going to maintenance mode didn’t make a difference. After the reboot here was the final version of ESXi:

~ # vmware -lv
VMware ESXi 5.1.0 build-1065491
VMware ESXi 5.1.0 Update 1

and luckily hostd was up and running:

~ # /etc/init.d/hostd status
hostd is running.
