HP customer self repair (CSR) programs allow you to repair your StorageWorks product. If a CSR part needs replacing, HP ships the part directly to you so that you can install it at your convenience. Some parts do not qualify for CSR. Your HP-authorized service provider will determine whether a repair can be accomplished by CSR.

Page 17: I/O Modules
Two I/O modules provide the interface between the disk enclosure and the host controllers, see Figure 5. For redundancy, only dual-controller, dual-loop operation is supported. Each controller is connected to both I/O modules in the disk enclosure. HP StorageWorks 4400 Enterprise Virtual Array user guide...

Page 28: Storage System Racks
Each system configuration contains several disk enclosures included in the storage system. See Figure for a typical EVA4400 rack configuration. The standard rack for the EVA4400 is the 42U HP 10000 G2 Series rack. The EVA4400 is also supported with 22U, 36U, 42U 5642, and 47U racks.

Page 31: Rack Ac Power Distribution
The AC power distribution within a rack ensures a balanced load to each PDU and reduces the possibility of an overload condition. Changing the cabling to or from a PDM could cause an overload condition. HP supports only the AC power distributions defined in this user guide. 0131a 1.
Page 32: Rack System/E Power Distribution Components
PDUs 2 and 4 (optional) are mounted on the right side of the cabinet. Power cords connect these PDUs to the number 2 drive enclosure power supplies and to the controller enclosures.

To ensure efficient storage system operation, reserve some unallocated capacity, or free space, in each disk group. The recommended amount of free space is influenced by your system configuration. For guidance on how much free space to reserve, see the HP StorageWorks Enterprise Virtual Array configuration best practices white paper. See Best practices.

This improves performance by reducing the overhead incurred when servicing read I/Os on the non-managing controller. Implicit LUN transition is enabled in VCS 4.x and all versions of XCS. HP StorageWorks 4400 Enterprise Virtual Array user guide...
Page 40: Storage System Shutdown And Startup
I/Os. Implicit LUN transition is disabled for all members of an HP Continuous Access EVA DR group. Because HP Continuous Access EVA requires that all members of a DR group be managed by the same controller, it would be necessary to move all members of the DR group if excessive proxy reads were detected on any virtual disk in the group.

Page 74: Failure Scenarios
Failure scenarios HP-UX Fault stimulus Failure effect Server failure (host power-cycled) Extremely critical event on UNIX. Can cause loss of system disk. Short term: Data transfer stops. Possible I/O errors. Switch failure (SAN switch disabled) Long term: Job hangs, cannot umount disk, fsck failed, disk corrupted, need mkfs disk.

Page 76: Netware
Fault stimulus Failure effect If the LUN is not shared, I/O is suspended or process is terminated across this HBA until path is restored. If running OpenVMS 7.3-1 and the LUN is shared, another cluster node having direct access will take over serving the device, resulting in no loss of service. Server path failure In either case, no data is lost or corrupted.
