  2. Module 1 Designing and ImplementingCompaq StorageWorks

  3. 목 차 • Storage System 구성요소에 대한 이해 • Storage Subsystem 관리 환경 설정 및 구성 • HSG80 Controller Configuration 방법 • Raid 종류와 Setting 방법 • Troubleshooting

  4. RA8000 SCSI Buses 구조 • 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. 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. Setting the ID for the Enclosure 0, 2, and 3 are the only valid PVA settings

  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. External Cache Modules • Cache Modules • Left cache module : top controller • Right cache module : bottom controller

  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. 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 I/O Modules

  20. Console 환경 설정하기 • 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. Configuring Redundant Controllers Controller Failover Mode Type • Dual-Redundant (Transparent Failover Mode) • Multi-Bus Failover Mode

  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 방법 1. HSG80 Controller Terminal Emulation Program - Settings (using the Hyper Terminal) 2. 설정 확인 - SHOW THIS 3. HSG80 Controller 초기화(미사용컨트롤러 물리적제거후) • CONFIGURATION RESET • SET NOFAILOVER • Controller의 후면 확인 (Bottom Controller down된 상태 확인) • CONFIGURATION RESET 명령 수행 • DOWN된 BOTTOM CONTROLLER의 RESET BUTTON을 누른다. 4. SHOW THIS FULL (NODE ID 확인) - NODE ID가 모두 0로 설정되어 있는 것을 확인

  25. 5. SET THIS_CONTROLLER NODE_ID = XXXX-XXXX~ • - NODE ID 설정 후 Controller가 Restart되는 것이 요구됨. • RESTART THIS • - Controller가 restart된 후에 Controller Failover mode, Time과 Cache설정 등이 요구된다는 메시지를 확인할 수 있다. • SHOW THIS • - Controller의 Failover mode 및 Time등 기타 설정이 되어있지 않은 상태를 확인한다. • SET FAILOVER COPY = THIS • (SET MULTIBUS COPY = THIS) • SHOW THIS • - Time, Mirrored Cache설정이 되어 있지 않은 상태를 확인

  26. 10. SET THIS TIME = 07-NOV-2001:07:15:00 - 날짜 setting시에 월에 해당되는 항목 설정 시 주의 11. SET THIS MIRROR_CACHE - Controller 가 restart된다. • SHOW THIS - 결과 확인 후 마친다 • SET THIS PORT_1_TOPOLOGY = LOOP_SOFT - FC-Hub일 경우 사용 set THIS PORT_1_TOPOLOGY = FABRIC - FC-Switch일 경우 사용

  27. Raid 종류와 Setting 방법 • JBOD • RAID 0 : Stripe Set • RAID 1 : Mirror Set • RAID 5 : Raid Set • RAID 0+1 : Striped Mirrorset • Spare Set

  28. DISK 인식 방법 • Automatic 방식 - RUN CONFIG 2. Manual 방식 - ADD DISK PTLAddress PORT TARGET LUN (EX : ADD DISK DISK10000 1 0 0) DISKPTTLL Rule : P = Port Number TT = SCSI ID Number LL = Always 00

  29. Step 1 - JBOD HSG80> INITIALIZE DISK10000 HSG80> ADD UNIT D0 DISK10000 HSG80> SHOW DISK10000 HSG80> SHOW D0 Step 2 - RAID 0 : Stripe Set HSG80> ADD STRIPESET STR1 DISK20000 DISK30000 HSG80> INITIALIZE STR1 HSG80> ADD UNIT D1 DISK10000 HSG80> SHOW STR1 HSG80> SHOW D1

  30. Step 3 - RAID 1 : Mirror Set HSG80> ADD MIRRORSET MIRR1 DISK40000 DISK50000 HSG80> INITIALIZE MIRR1 HSG80> ADD UNIT D2 MIRR1 HSG80> SHOW MIRR1 HSG80> SHOW D2 Step 4 - RAID 5 : Raid Set HSG80> ADD RAIDSET R1 DISK10100 DISK20100 DISK30100 HSG80> INITIALIZE R1 HSG80> ADD UNIT D3 R1 HSG80> SHOW R1 HSG80> SHOW D3

  31. Step 5 - RAID 0+1 : Striped Mirrorset HSG80> ADD MIRRORSET MIRR2 DISK40100 DISK50100 HSG80> ADD MIRRORSET MIRR3 DISK60000 DISK60100 HSG80> ADD STRIPESET STR2 MIRR2 MIRR3 HSG80> INITIALIZE STR2 HSG80> ADD UNIT D4 STR2 HSG80> SHOW STR2 HSG80> SHOW D4 Step 6 – Spare Set HSG80> ADD SPARESET DISK60200 HSG80> SHOW SPARESET HSG80> SHOW STORAGE

  32. Failedset Disk Auto Rebuilding 설정 HSG80> SET FAILEDSET AUTOSPARE HSG80> SHOW FAILEDSET HSG80> SET FAILEDSET NOAUTOSPARE HSG80> SHOW FAILEDSET UNIT, STORAGE, DISK 삭제 UNIT : HSG80> DELETE UNIT명 HSG80> SHOW UNIT STORAGE : HSG80> DELETE STORAGE명 HSG80> SHOW STORAGE DISK : HSG80> DELETE DISK명 HSG80> SHOW DISK

  33. FAIL DISK REPLACE(디스크교체시) HSG80> SHOW STORAGE HSG80> DEL FAILEDSET DISK명 HSG80> SHOW DISK HSG80> DELETE DISK명 ( NEW DISK REPLACE ) HSG80> ADD DISK DISK명 HSG80> SHOW FAILED_RAIDSET명 HSG80> SET FAILED_RAIDSET명 NOPOLICY HSG80> SET FAILED_RAIDSET명 RECONSTRUCT = FAST ( DATA ACCESS SPEED = LOW DATA REBUILDINF SPEED = FAST RAIDSET ONLY ) HSG80> SET FAILED_RAIDSET명 REPLACE = NEWDISK명 HSG80> SHOW FAILED_RAIDSET명 HSG80> SET FAILED_RAIDSET명 RECONSTRUCT = NORMAL HSG80> SET FAILED_RAIDSET명 POLICY = BEST_PERFORMANCE

  34. Assigning LUNs (Fibre Channel) • ADD UNIT {LUN} {Storage Set Name} • Port 1 displays units D0 through D99 • Port 2 displays units D100 through D199 • Example : ADD UNIT D101 M1
