To replace a power supply unit (PSU) in a storage controller of an XtremIO cluster, a specific command needs to be executed.

The correct command to initiate this process is replace-storage-controller-psu sc-psu-id=1 cluster-id='ABC123'.

This command specifies the action to replace the PSU (replace-storage-controller-psu), the PSU ID (sc-psu-id=1), and the specific cluster ID (cluster-id='ABC123').

Using this command ensures that the correct PSU in the specified cluster is prepared for replacement.

When creating a cluster, in addition to the cluster name, the following parameters are required: the expected number of X-Bricks, the IP address of X1-SC1 (the first Storage Controller), and the package name. These parameters are essential for setting up the cluster configuration and ensuring proper communication between components.

ESRS (EMC Secure Remote Services) configuration verification is typically done using commands that check for system notifications and configurations.

The show-syslog-notifier command is used to verify the settings and configuration of syslog notifications, which is part of the ESRS setup.

This command helps in ensuring that the notifications are correctly configured and functioning as intended, allowing for remote monitoring and management.

To successfully operate Technician Advisor on an XtremIO X2, TCP ports 80 and 443 need to be open between the XMS (XtremIO Management Server) and X1-SC1 (Storage Controller). These ports are used for HTTP and HTTPS communication, respectively, allowing for secure management and operation of the storage system.

The XtremIO X2 storage system can be expanded for capacity (Scale-Up) or both capacity and performance (Scale-Out). The system begins with a single building block, called an X-Brick, with a minimum of 18 SSDs. When additional capacity is required, the system scales up, with up to 72 SSDs for a single X-Brick1. Therefore, to upgrade a single X-Brick XtremIO X2 cluster that already contains 36 SSDs, the minimum number of SSDs required would be 18, which is the base configuration for an X-Brick.
