2 Designing and Implementing Compaq StorageWorks Module 1

3 1.Storage System 2.Storage Subsystem 3.HSG80 Controller Configuration 4.Raid Setting 5.Troubleshooting

4 4 RA8000 SCSI Buses All devices in the same column are on the same SCSI bus, or port. All devices in the same row have the same device address, or target ID. Device addresses 4 and 5 are reserved and not to be used.

5 SBB Power Supply Placement

6 SBB Power Supplies At least four are necessary to power the cabinet -Five power supplies are required for a standard power configuration (4+1) -One Power Supply is redundant and will take over for any single failed power supply. -Eight power supplies and a B power entry module are required -for fully redundant power (4+4 configuration) -Power supplies are hot-swappable (if there are more than four)

7 7 Environmental Monitoring Unit(EMU)

8 EMU Error Detection –The EMU will detect High temperature Failed disk drives Cache battery low voltage or failure Controller errors Ultra SCSI termination errors Blower failures

9 EMU and System Shutdown –The EMU will shutdown the subsystem cabinet if: A blower is removed for more than eight minutes If all four blowers in one vertical bank are defective and not replaced within 8 minutes If there are less than four functioning power supplies If any two temperature sensors register 50 Degrees Centigrade(122 Degrees F). This is the EMU default setting.It can be changed.

10 Power Verification and Address Unit (PVA) 1. Power switch 2. UPS Communications 3. SCSI target wheel

11 Power Verification and Address Unit (PVA) –Works with the EMU and acts as a redundant fault monitor –The PVA will shut down the subsystem if the EMU is removed for more then eight minutes –The PVA cannot be hot swapped –Valid PVA SCSI settings are 0, 2 and 3 only –If the PVA SCSI setting must be changed, the cabinet must be shut down and powered off for the changes to take effect

12 12 Setting the ID for the Enclosure 0, 2, and 3 are the only valid PVA settings

13 13 HSG80 RAID controller

14 Controller Operator Control Panel (OCP) 1. FC Ports 2. ACS Slot 3. Maintenance Port 4. Operator Control Panel

15 Array Controller Software PCMCIA Card –Each controller requires a PCMCIA card to operate –PCMCIA card contains controller firmware –Firmware is downloaded into volatile memory at startup

16 Cache Modules –Left cache module : top controller –Right cache module : bottom controller External Cache Modules

17 External Cache Batteries (ECB) Cache Batteries –Cache batteries are checked every 24 hours –Weak Cache batteries checked every 4 minutes for 10 hours –When fully charged, an ECB can preserve 512 MB of cache memory for 24 hours, or 64 MB of cache memory for 48 hours –Cache battery LEDs Slow flashing = discharging Rapid flashing = charging Steady green = fully charged –Battery cut-off button disconnects battery from cache

18 Dual Speed Blowers –Can be hot swapped –Can be set to run at high speed continually –If a blower is removed, the subsystem will shut down after eight minutes

19 I/O Modules –Six modules with dual pairs of 68-pin VHD connectors. –One for each internal SCSI bus –Connect expansion cabinets to the primary cabinet –Wide-Ultra SCSI-2, single-ended termination. –Cable length between cabinets is restricted to 1.5 meters

20 Console Establishing a CLI Session –Connect the serial cable (DB9 to RJ12) from the maintenance port of the controller to any terminal or to the COM Port of a PC running a terminal emulation program Terminal Setting (using Hyper Terminal) –Use these parameters to establish a session 9600 bps 8 data bits 1 stop bit No parity No flow control –Press the Enter key

21 Controller Failover Mode Type Dual-Redundant (Transparent Failover Mode) Multi-Bus Failover Mode Configuring Redundant Controllers

22 Dual–Redundant Mode SET FAILOVER COPY = THIS or SET FAILOVER COPY = OTHER

23 Multi-Bus Failover Mode SET MULTIBUS COPY = THIS or SET MULTIBUS COPY = OTHER

24 HSG80 Controller Configuration 1. HSG80 Controller Terminal Emulation Program - Settings (using the Hyper Terminal) 2. - SHOW THIS 3. HSG80 Controller ( ) -CONFIGURATION RESET -SET NOFAILOVER -Controller (Bottom Controller down ) -CONFIGURATION RESET -DOWN BOTTOM CONTROLLER RESET BUTTON. 4. SHOW THIS FULL (NODE ID ) - NODE ID 0

25 5. SET THIS_CONTROLLER NODE_ID = XXXX- XXXX~ - NODE ID Controller Restart. 6.RESTART THIS - Controller restart Controller Failover mode, Time Cache. 7.SHOW THIS - Controller Failover mode Time. 8.SET FAILOVER COPY = THIS (SET MULTIBUS COPY = THIS) 9.SHOW THIS - Time, Mirrored Cache

26 10. SET THIS TIME = 07-NOV-2001:07:15:00 - setting 11. SET THIS MIRROR_CACHE - Controller restart. 12.SHOW THIS - 13.SET THIS PORT_1_TOPOLOGY = LOOP_SOFT - FC-Hub set THIS PORT_1_TOPOLOGY = FABRIC - FC-Switch

27 Raid Setting 1.JBOD 2.RAID 0 : Stripe Set 3.RAID 1 : Mirror Set 4.RAID 5 : Raid Set 5.RAID 0+1 : Striped Mirrorset 6.Spare Set
