paths
An additional storage group feature that performs the following tasks:
Lists all of the paths from the host server to the storage group
Displays whether the path is enabled or disabled
Each path contains the following fields:
HBA — Device name of the HBA in the host system
HBA Port — Unique ID for the HBA port connected to the storage system
SP Port — Unique ID for the storage processor port connected to the HBA port
SP ID — ID of the storage processor
Navisphere Manager
Navisphere Manager provides centralized storage management and configuration from a single management console. Using a GUI, Navisphere
Manager allows you to configure and manage the disks and components in one or more shared storage systems.
You can access Navisphere Manager through a Web browser. Using Navisphere Manager, you can manage a Dell | EMC storage system locally
on the same LAN or through an Internet connection. Navisphere components (Navisphere Manager UI and Storage Management Server) are
installed on a Dell | EMC storage system. You can access Navisphere Manager by opening a browser and entering the IP address of the
storage system's SP. Navisphere Manager downloads to your system and runs in the web browser.
Optionally, you can run Navisphere Management Server for Windows. This software component installs on a host system connected to a Dell |
EMC storage system, allowing you to run Navisphere Storage Management Server on the host system.
Using Navisphere Manager, you can:
Create storage groups for your host systems
Create, bind, and unbind LUNs
Change configuration settings
Monitor storage systems
See " Storage Management Software " for more information on Navisphere Manager.
EMC PowerPath
PowerPath automatically reroutes Fibre Channel I/O traffic between the host system and a Dell | EMC CX-series storage system to any
available path if a primary path fails for any reason. Additionally, PowerPath provides multiple path load balancing, allowing you to balance the
I/O traffic across multiple SP ports on a CX400 or CX600.
Updating the Storage System Configuration Settings
Some Dell | EMC storage systems may have shipped with preconfigured settings that may cause the cluster systems to malfunction in some
environments. To optimize storage system performance, update the following processor enclosure settings as listed in Table 2-5 using a Web
browser and Navisphere Manager.
