Storage system shutdown and powerup The storage system is shut down using HP Command View EVA. The shutdown process performs the following functions in the indicated order: 1. 2. 3. 4. 5. Flushes cache Removes power from the controllers Disables cache battery power Removes power from the drive enclosures Disconnects the system from HP Command View EVA NOTE: The storage system may take a long time to complete the necessary cache flush during controller shutdown when snapshots are being used.
NOTE: Before applying power to the rack, ensure that the power switch on each HSV controller is off. 3. Power on the circuit breakers on both EVA rack PDUs. Verify that all drive enclosures are operating properly. The status indicator and the power indicator should be on (green). 4. Wait three minutes and then verify that all disk drives are ready. The drive ready indicator and the drive online indicator should be on (green). 5. Power on the upper controller. It takes the roll of master controller. 6.
5. Enter CAPTURE CONFIGURATION, specifying the full path and filename of the output files for the configuration data. The configuration data is stored in a series of from one to five files, which are SSSU scripts. The file names begin with the name you choose, with the restore step appended. For example, if you specify a file name of LargeEVA.txt, the resultant configuration files would be LargeEVA_Step1A.txt, LargeEVA_Step1B, etc. The contents of the configuration files can be viewed with a text editor.
Adding disk drives to the storage system As your storage requirements grow, you may be adding disk drives to your storage system. Adding new disk drives is the easiest way to increase the storage capacity of the storage system. Disk drives can be added online without impacting storage system operation. Guidelines for adding disk drives When adding new disk drives to the storage system, you should ensure that the disk drives are installed in the correct positions to maintain availability.
NOTE: Standard and FATA disk drives must be in separate disk groups. Disk drives of different capacities and spindle speeds can be included in the same disk group, but you may want to consider separating them into separate disk groups. 1 2 CX8167-ST Figure 6 Sequential building of vertical disk groups 1. Disks installed in first group 2. Disks installed in second group Adding a disk drive This section describes the procedure for adding a Fibre Channel disk drive. Removing the drive blank 1.

Handling fiber optic cables This section provides protection and cleaning methods for fiber optic connectors. Contamination of the fiber optic connectors on either a transceiver or a cable connector can impede the transmission of data. Therefore, protecting the connector tips against contamination or damage is imperative. The tips can be contaminated by touching them, by dust, or by debris. They can be damaged when dropped.
4 Enterprise Virtual Array hardware components This chapter describes the Enterprise Virtual Array hardware components. Topics to be discussed include: • • • • Fibre Channel drive enclosures Fibre Channel loop switches HSV controllers Racks Fibre Channel drive enclosures The drive enclosure contains the disk drives used for data storage. A storage system includes multiple drive enclosures. The major components of the enclosure are: • • • • • • • • 2.

See Figure 11.
2 1 3 0107a Figure 11 I/O module 1. Status indicators (Upper port, Power, and Lower port) 2. Upper port 3. Lower port The I/O modules are functionally identical, but are not interchangeable. Module A can only be installed at the right end of the enclosure, and module B can only be installed at the left end of the enclosure. See Figure 10. Each I/O module has two ports that can both transmit and receive data for bidirectional operation. Activating a port requires connecting a FC cable to the port.
Table 7 Operational I/O module status indicators Upper Power Lower Off On Off • I/O Module is operational On Flashing, then On On • Top port—Fibre Channel drive enclosure signal detected. • Power—Flashes for about 90 seconds after initial power application, then remains constant. • Bottom port—Fibre Channel drive enclosure signal detected. On On On • Top port—Fibre Channel drive enclosure signal detected. • Power—Present. • Bottom port—Fibre Channel drive enclosure signal detected.
Fibre Optic Fibre Channel cables The Enterprise Virtual Array uses orange, 50-μm, multi-mode, fiber optic cables for connection to the SAN. The fiber optic cable assembly consists of two, 2–m fiber optic strands and small form-factor connectors on each end. See Figure 13. To ensure optimum operation, the fiber optic cable components require protection from contamination and mechanical hazards. Failure to provide this protection can cause degraded operation.
Up to 14 disk drives can be installed in a drive enclosure. Disk drive status indicators Three status indicators display the drive operational status. Figure 15 shows the disk drive status indicators. Table 9 provides a description of each status indicator. Figure 15 Disk drive status indicators 1. Activity 2. Online 3.

NOTE: An error always generates a condition report. Not all condition reports are generated by errors. Error condition categories Each error condition is assigned to a category based on its impact on disk enclosure operation. The following four error categories are used: • Unrecoverable—the most severe error condition, it occurs when one or more enclosure components have failed and have disabled some enclosure functions.
Correcting the error removes the associated condition from the error queue. Replacing the EMU will also clear the error conditions. The order in which the EMU displays the error queue information is based on two factors: • The severity of the error • The time the error occurred The most severe error in the queue always has precedence, regardless of how long less severe errors have been in the queue. This ensures that the most severe errors are displayed immediately.

Moving and stabilizing a rack WARNING! The physical size and weight of the rack requires a minimum of two people to move. If one person tries to move the rack, injury may occur. To ensure stability of the rack, always push on the lower half of the rack. Be especially careful when moving the rack over any bump (e.g., door sills, ramp edges, carpet edges, or elevator openings). When the rack is moved over a bump, there is a potential for it to tip over.
