1、FC60 Workshop,Module 1 - Product Introduction Module 2 - Hardware Configuration Module 3 - Operation & Maintenance Module 4 - Discussion,Module 3 - Operation & Maintenance,Operation Concepts Daily Operations Maintenance Tips,Operation Concepts,Supported RAID level Raid 1 - Disk Mirroring Raid 0/1 -

2、Block Mirroring Raid 5 - Striping and Distributed Parity Supported LUNs Maximum 30 LUNs supported Raid level, capacity and stripe depth can config for each LUN Implementation Volume Set Addressing, can supported 32 LUNs,Operation Concepts,Volume Set Addressing,Operation Concepts - Cache,Read cache a

3、lways enabled Write cache Enabled by default if two controller present Cannot disabled by diagnostics All host writes are send to controller cache Mirrored of both controllers Write cache will disabled whenever a battery is fault, removed or not full charge Whenever a controller is fault, in passive

4、 mode or removed During power failure cache maintained by BBU in 5 days,Operation Concepts - ALT,Auto LUN transfer provides fail over access to the LUNs from one controller to the other ALT is always enabled and cannot be disabled, it is set by factory in NVSRAM LVM is used to configure primary and

5、alternate path to LUN. (also LUN ownership) If a controller fails, LVM will request access through alternate path LVM will continue to poll the failed path, and reestablish access when it recovered,Daily Operations - Software Tools,First release require HP-UX 11.0 Support Plus CD 9909 or later XSWHW

6、CR1100 B.11.00.46 or above. OnlineDiag B.11.11.10.12 or above. (STM A.17.00) PHCO_19571 B.11.00.07 HP Array Manager/60 cumulative patch (*wrong in 9912 CD) NOTE: Hardware Critical Patch bundle must be installed before Support Tools Bundle,Daily Operations - Three Tools,SAM - Most user friendly for c

7、onfigure but lack ability of diagnostic AM60 Tools - Most powerful in diagnostic, also strong in configuration. STM - Mainly used for diagnostics. Especially STM/inforlog is a must for trouble shooting,Daily Operations - AM60 Tools,Location - /opt/hparray/bin AM60Srvr - Background deamon amdsp - Dis

8、play status information, configuration ammgr - Manage overall characteristics (alias, cache etc) amcfg - Configure LUN etc amutil - Maintenance tool, set rebuild priority etc amdload - Download firmware amlog - View logs,Daily Operations - Installation,Basic Steps - Reference Quick installation guid

9、e Tips for avoid trouble in future: Good hardware connection/setting is first of first If possible, use LUN 0 as lock disk If possible, put non-critical data on LUN 0 Note primary/alternate link when create VG Confirm amdsp and STM/Infolog can work Collect amdsp -a and STM/Infolog data after finishe

10、d ! Best do syswipe ( Must when do field integrated installation ),Daily Operations - Power up and down,Power Up: 1) Power up all SC10 Disk Enclosures 2) Wait 2 minutes 3) Power up the FC60 Controller Enclosure 4) Start I/O from host(s) Power Down: 1) Stop all I/O to the FC60 or shutdown the host(s)

11、 2) Wait for the Write Cache LED to turn off (Approximately 60 seconds) 3) Power down the FC60 Controller Enclosure 4) Power down the SC10 Disk Enclosures,Maintenance Topic - For customer,Check all LEDs from front and rear Check status by amdsp -a Check STM/inforlog Check by amlog,Always Do followin

12、g regularly,Maintenance Topic - Firmware,Responsible for setting operating parameters and determining array behavior. There are three types of firmware files of controller modules Bootware - executed when power on, self test Firmware - manage controller operation NVSRAM -configuration settings of co

13、ntroller Cannot modified in field If required, modifications would be downloading Must download allow the sequence, B-F-N Auto Code Synchronization - new installed controller copy firmware from old one,Maintenance Topic - GHS,Similar to Hot Spare disk in NIKE GHS disk pull into a unused slot will make it become GHS slot Disk pull into a GHS slot will become GHS disk GHS disk insert into a LUN slot Usually it will be treated as replaced disk and do rebuild But
