How to Install, Update, and Remove the Nimble Connection Manager on ESXi

There are a few ways to install Nimble Connection Manager (NCM) on your ESXi hosts. The easiest way is to add the appropriate download source to VMware Update Manager (VUM) in your vCenter, then create and attach a baseline for Nimble Connection Manager to each of your ESXi hosts attached to the HPE Nimble array. Doing so will ensure that Nimble Connection Manager is installed or updated during your normal VMware Update Manager update cycle which will keep Nimble Connection Manager updated across your infrastructure. For those that need them, here are the source URLs:

Nimble Connection Manager Download Sources for VMware Update Manager
ESX VersionDownload Source
ESXi 5.xhttps://update.nimblestorage.com/esx5/ncm/index.xml
ESXi 6.0https://update.nimblestorage.com/esx6/ncm/index.xml
ESXi 6.5https://update.nimblestorage.com/esx6.5/ncm/index.xml

Now that you have the download sources, what do you do with them? For starters, add them to VMware Update Manager (VUM). For detailed instructions on how to do that, check out my blog post on the subject, or VMware Docs.

Another option is to install Nimble Connection Manager directly to the host. There are a few prerequisites for this method:

  1. Enable SSH on the host.
    1. Select the host, click Manage, and keep Settings selected.
    2. Click Security Profile.
    3. In the Services section, click Edit.
    4. Select SSH.
      • To temporarily start or stop the service, click the Start or Stop button.
      • To change the Startup policy across reboots, select Start and stop with host and reboot the host.
    5. Click OK.
  2. Put the host into Maintenance Mode.
  3. Launch an SSH client (I typically use PuTTY), and log into the ESXi host as root.

Now that you’re logged into the ESXi host as root, execute one of the following commands to install the version of Nimble Connection Manager (NCM) appropriate for the version of ESXi installed on the host, verify that the Nimble Connection Manager (NCM) is installed, or remove the Nimble Connection Manager (NCM) packages:

To install the Nimble Connection Manager (NCM) on an ESXi 5.5 host, execute the following command:

vib install -d https://update.nimblestorage.com/esx5/ncm

To install the Nimble Connection Manager (NCM) on an ESXi 6 host, execute the following command:

vib install -d https://update.nimblestorage.com/esx6/ncm

To install the Nimble Connection Manager (NCM) on an ESXi 6.5 host, execute the following command:

vib install -d https://update.nimblestorage.com/esx6.5/ncm

To verify that Nimble Connection Manager (NCM) is installed, execute the following command:

esxcli software vib list grep nimble

To remove the Nimble Connection Manager (NCM):

/etc/init.d/sfcbd-watchdog stop
esxcli software vib remove -n nimble-ncs --maintenance-mode
esxcli software vib remove -n nimble-psp --maintenance-mode

After the Nimble Connection Manager (NCM) has been either installed or removed, the ESXi host must be rebooted.
