Preparing ESXi host
Prepare one ESXi host at a time for upgrading the ESXi host version or to patch the ESXi host.
1. If you want to use a new vCenter 6.0 server to manage Fluid Cache cluster, disconnect the hosts
from the existing vCenter 5.5 server, and then connect the hosts to vCenter cluster on the vCenter
6.0 server.
If the Fluid Cache hosts are already on a vCenter 6.0 system, continue with step 2.
2. Select a single ESXi host that you want to upgrade and migrate all the active guests, other than Fluid
Cache appliance guest.
3. Shutdown of the Fluid Cache appliance guest by using one of the following methods:.
• In case of thick client, right-click the guest, from the Power menu, click Shut Down Guest.
• In case of thin client, right-click the guest, and click Shut Down Guest OS.
NOTE: To shut down the host, do not select the Power Off option, which immediately turns off
the appliance without proper shutdown process.
You can monitor the status of the shutdown process in the Cache Overview page. Monitor the
shutdown state of the guest appliance that is being shut down from the web page of the other Fluid
Cache appliance web page.
4. On the Cache Overview page, monitor and verify the following:
a. The state of the cache devices changes to CACHEDEV_STATE_SHUTTING_DOWN (one device
at a time), and the In Use (GB) number will gradually reduce to zero.
b. After the cache device shuts down completely, the status changes to
CACHEDEV_STATE_INACTIVE.
c. When shutdown is complete, verify the following on Fluid Cache web page:
• On the Cache Server Stats page, the Devices state changes to no connection.
• On the Block Device Stats page, the status of all the cache devices in the host changes to
offline or disconnected.
d. After all the components of appliance shuts down, confirm that Fluid Cache guest appliance is
turned off.
5. Repeat the steps for other ESXi hosts.
• To upgrade the ESXi host version from 5.5 to 6.0, see Upgrading ESXi Hosts Version
• To patch the ESXi host version, see Patching the ESXi host version
