A customer plans to start using Cache Partition Manager (CPM) on a Hitachi Unified Storage system. Which two statements regarding the installation and configuration of this Program Product are…

Question

Options

• AConfiguring CPM requires a reboot.
• BAdding the CPM license key requires a reboot.
• CInstallation and configuration of CPM can be done online.
• DAdding the CPM license key does not require rebooting the system.

Explanation

C and D are correct.

Cache Partition Manager on Hitachi Unified Storage is designed as a non-disruptive feature - both adding the license key and performing the configuration can be completed online, without rebooting the system. This is a key advantage of modern enterprise storage management, where downtime for software activation would be unacceptable in production environments.

Why A is wrong: Configuring CPM does not require a reboot; configuration is performed online through the storage management software while the system remains operational.

Why B is wrong: This directly contradicts D - adding the license key is a non-disruptive operation and requires no system reboot.

Memory tip: Think of the letters C and D as standing for "Continuous Downtime-free" - both the installation/configuration (C) and the license key addition (D) are online operations. On Hitachi enterprise storage, Program Products are designed to be activated without service interruption, so any answer suggesting a reboot is a red flag.
