one – standby.
About this task
To minimize system downtime, you can upgrade the existing Spectrum Control Base or install
its new release along with completing failover between active and standby instances in vSphere
environment.Procedure
- Copy the upgrade or installation package files to a temporary folder on a virtual machine that
is hosting Spectrum Control Base.
- Upgrade or install the standby Spectrum Control Base instance. See Upgrading an existing installation or Performing first-time installation of Spectrum Control Base.
- Verify the standby instance connectivity to a storage system, by using the
sc_storage_array list command. A proper connectivity to a storage system is indicated by Yes in the
Connected field, as illustrated in the following
example.

- Complete the active Spectrum Control Base failover to the standby instance, by restarting the
guest operation system of the virtual machine that is hosting the active Spectrum Control
Base. The failover process can take up to 8 minutes to complete. As a result, the standby
instance becomes active, running the newly upgraded or installed Spectrum Control Base.
- Repeat the upgrade/install and failover processes for the remaining Spectrum Control Base
instances.
