    Altos RAIDWatch User Guide The enclosure window also includes Logical view as a sub-function. The Logical view displays the logical relationship among member drives of a logical configuration. Drives belonging to the same logical unit will be displayed in the same color for ease of identification. A.3.3 Powerful Event Notification Function Altos RAIDWatch can notify system administrators of event occurrences and status changes in the disk array system.

  • Page 19: Conceptual Foundation

    Introduction A.4 Conceptual Foundation In order for Altos RAIDWatch to function properly, different software modules must be correctly installed on different servers and stations in a given LAN or WAN. Assuming that a given network has multiple RAID systems, one RAID connected server will need to be chosen as the main server. This point is particularly important if Altos RAIDWatch will be operated via web browsers as the main server will need to be a web server.
  • Page 20 Altos RAIDWatch User Guide Notes 1 OS drivers are required for Solaris servers. 2 OS patches are required to run JRE on Solaris, AIX and Linux servers. 3 Browser preferences must be edited for browsers running under Windows systems. The requirements for installing Event Monitor are exactly the same as those for Altos RAIDWatch Manager.

    Troubleshooting Appendix B Troubleshooting This appendix provides troubleshooting tips for common problems you may encounter while using Altos RAIDWatch Manager. It includes the following topics: • Common oversights, B.1 on page 177. • Error codes, B.2 on page 178. • Error messages, B.3 on page 179. B.1 Common Oversights Check the following first before you run Altos RAIDWatch or if you are having trouble.

  • Page 192: Error Codes

    Altos RAIDWatch User Guide Check the Primary and Secondary agents #ps -eaf|grep primary #ps -eaf |grep secondary If either program is not running, please open a terminal session and run it manually. IP Settings: Each RAID host server must have a unique IP address assigned. Check the IP address of each RAID host.

  • Page 193: Error Messages

    Troubleshooting What You Can Do: Check your network environment to determine whether or not the Primary agent is available. Use a “ping” utility to see if the server exists on the network. Code: RC=2 • Meaning: The Primary agent did not understand the last Altos RAIDWatch Manager command. What You Can Do: Please check the firmware version of controller to see if it is compatible with your version of Altos RAIDWatch.

    Altos RAIDWatch User Guide Explanation: Please assign one PID to each drive channel. • Message: Channel settings failed! Explanation: Please check the channel settings. • Message: Drive channel can only have one ID! Please remove ID from PID list first, and then add.
  • Page 195 Troubleshooting • Message: Setup redundant controller failed! Explanation: Check the redundant controller configuration. See if the PID and SID of drive and host channels are all correct and if the logical drives (volumes) are correctly assigned. All other Altos RAIDWatch Manager error messages should be fairly self-explanatory.

    RAID Levels Appendix C RAID Levels This appendix provides a functional description of Redundant Array of Independent Disks (RAID). This includes information about RAID and available RAID levels. C.1 RAID Description Redundant Array of Independent Disks (RAID) is a storage technology used to improve the processing capability of storage systems.

  • Page 199: Raid 1(0+1)

    RAID Levels In disk mirroring, the total disk capacity is equivalent to half the sum of the capacities of all SCSI drives in the combination. Thus, combining four 250GB SATA drives, for example, would create a single logical drive with a total disk capacity of 1TB. This combination of drives appears to the system as a single logical drive.

  • Page 200: Raid 3

    Altos RAIDWatch User Guide C.6 RAID 3 RAID 3 implements block striping with dedicated parity. This RAID level breaks data into logical blocks, the size of a SCSI disk block, and then stripes these blocks across several drives. One drive is dedicated to parity.

    Glossary Glossary Fibre (Also known as “fibre channel.”) . A device (in the case of RAID, a data storage device) protocol capable of high data transfer rates. Fibre channel simplifies data bus sharing and supports not only greater speed, but also more devices on the same bus. Fibre channel can be used over both copper wire and optical cable.
  • Page 204 Altos RAIDWatch User Guide Parity . Parity checking is used to detect errors in binary-coded data. The fact that all numbers have parity is commonly used in data communications to ensure the validity of data. This is called parity checking. Primary Agent .
  • Page 205 Glossary Write-back Cache . Many modern disk controllers have several megabytes of cache on board. Inboard cache gives the controller greater freedom in scheduling reads and writes to disks attached to the controller. In write-back mode, the controller reports a write operation as complete as soon as the data is in the cache.
