APPENDIX 98 Appendix C SNMP Operation & Installation C-1 Overview McRAID storage manager includes a rm ware-embedded Simple Network Management Protocol (SNMP) agent and SNMP Extension Agent for the Areca RAID controller . An SNMP-based management application (also known as an SNMP manager) can monitor the disk arra y .
99 APPENDIX C-3 SNMP Installation Perform the following steps to install the Areca RAID controller SNMP function into the SNMP manager . The installation of the SNMP manager is accomplished in sever al phases: Step 1. Installing the SNMP manager software on the client Installing the SNMP manager software on the client.
APPENDIX 100 Step 3. SNMP Service Method With Areca series RAID controllers, there are 2 service methods to get SNMP: in-band Thunderbolt port and onboard NIC. 1. Service Method-1: Using in-band Thunderbolt port (ArcHT TP proxy server) Pa y attention to these: • Do not check mark the option: “SNMP Through PCI” .
101 APPENDIX T o enable the controller to send the SNMP traps to client SNMP manager using the IP address assigned to the oper ating system, such as Net- SNMP manager , you can simply use the SNMP function on the ArcHT TP proxy server utility .
APPENDIX 102 The rmware-embedded SNMP agent manager monitors all system events and the SNMP function becomes functional with no agent software required. When you open the "SNMP Conguration" link, y ou will see the following settings: 1.
103 APPENDIX Appendix D Event Notication Congurations The controller classies disk arra y events into four levels depending on their severity .
APPENDIX 104 Event Level Meaning Action Start Initialize W arning V olume initialization has started Start Rebuilding W arning V olume rebuilding has started Start Migrating W arning V olume migration.
105 APPENDIX C. RAID Set Event Event Level Meaning Action Create RaidSet W arning New RAID set created Delete RaidSet W arning Raidset deleted Expand RaidSet W arning Raidset expanded Rebuild R aidSet Warning R aidset rebuilding RaidSet Degraded Urgent Raidset degr aded Replace HDD D.
APPENDIX 106 HT TP Log In Serious a HTTP login detected T elnet Log Serious a T elnet login detected InVT100 Log In Serious a VT100 login detected API Log In Serious a API login detected Lost Rebuilding/ MigrationLBA Urgent Some rebuilding/ migration r aidset member disks missing before power on.
107 APPENDIX Appendix E RAID Concept RAID Set A RAID set is a group of disks connected to a RAID controller . A RAID set contains one or more volume sets. The RAID set itself does not dene the RAID level (0, 1, 1E, 3, 5, 6, 10, 30, 50 60, etc); the RAID level is dened within each volume set.
APPENDIX 108 In the illustration, v olume 1 can be assigned a RAID level 5 of operation while v olume 0 might be assigned a RAID level 1E of operation. Alternativ ely , the free space can be used to create vol- ume 2, which could then be set to use RAID level 5.
109 APPENDIX RAID set. Then, data on the existing volume sets (residing on the newly expanded RAID set) is redistributed evenly across all the disks. A contiguous block of unused capacity is made av ailable on the RAID set. The unused capacity can be used to create additional volume sets.
APPENDIX 110 • Online RAID Level and Stripe Size Migration For those who wish to later upgr ade to any RAID capabilities, a system with online RAID level/stripe size migr ation allows a simplied upgrade to an y supported RAID level without having to reinstall the operating system.
111 APPENDIX of disk failure(s). In the case of disk failure, the volume set transitions from migr ating state to (migrating+degr aded) state. When the migration is completed, the v olume set tran- sitions to degraded mode. If a global hot spare is present, then it further transitions to rebuilding state.
APPENDIX 112 cal drive that has been marked as a hot spare and therefore is not a member of any RAID set. If a disk driv e used in a volume set fails, then the hot spare will automatically tak e its place and he data previously located on the failed drive is reconstructed on the hot spare.
113 APPENDIX In the normal status, the newly installed drive will be recon- gured an online free disk. But, the newly -installed drive is automatically assigned as a hot spare if any hot spare disk was used to rebuild and without new installed drive replaced it.
APPENDIX 114 RAID controller allows user to choose the task priority (Ultr a Low (5%), Low (20%), Medium (50%), High (80%)) to bal - ance volume set access and background tasks appropriately . For high arr ay performance, specify an Ultr a Low value. Like volume initialization, after a volume rebuilds, it does not re - quire a system reboot.
115 APPENDIX cover able read error , the correct data will be tr ansferred to the host and that location will be tested by the drive to be certain the location is not defective. If it is found to hav e a defect, data will be automatically relocated, and the defective location is mapped out to prevent future write attempts.
APPENDIX 116 vides an additional level of protection. In the event of a power failure, a BBM supplies power to retain data in the RAID con- troller’s cache, thereb y permitting any potentially dirty data in the cache to be ushed out to secondary stor age when power is restored.
117 APPENDIX Appendix F Understanding RAID RAID is an acronym for R edundant Array of Independent Disks. It is an arra y of multiple independent hard disk drives that provides high performance and fault tolerance. The RAID controller imple - ments sever al levels of the Berkeley RAID technology .
APPENDIX 118 RAID 1 RAID 1 is also known as “disk mirroring”; data written on one disk drive is simultaneously written to another disk drive. R ead performance will be enhanced if the arra y controller can, in paral- lel, access both members of a mirrored pair .
119 APPENDIX RAID 10(1E) RAID 10(1E) is a combination of RAID 0 and RAID 1, combining stripping with disk mirroring. RAID Level 10 combines the fast performance of Level 0 with the data redundancy of lev el 1.
APPENDIX 120 RAID 5 RAID 5 is sometimes called striping with parity at byte level. In RAID 5, the parity information is written to all of the drives in the controllers rather than being concentr ated on a dedicated parity disk. If one drive in the system fails, the parity information can be used to reconstruct the data from that drive.
121 APPENDIX RAID 6 RAID 6 provides the highest reliability . It is similar to RAID 5, but it performs two different parity computations or the same compu- tation on overlapping subsets of the data. RAID 6 can offer fault tolerance greater than RAID 1 or RAID 5 but only consumes the capacity of 2 disk drives for distributed parity data.
APPENDIX 122 Important : RAID level 00, 100, 30, 50 and 60 can support up to eight RAID set. If volume is RAID level 00, 100, 30, 50, or 60, you can’t change the volume to another RAID level. If volume is RAID level 0, 1, 10(1E), 3, 5, or 6, y ou can’ t change the volume to RAID level 00, 100, 30, 50, or 60.
