    Creating and Managing Arrays and Partitions Using the OCP, you can perform the following array-related functions: Create arrays (see page Manage arrays (see Manage partitions (see Creating Arrays You can create an array at any time. drive requirements for each RAID level. Table 2-1.

  • Page 12: Creating A Single-Partition Array

    Note: Before you create more than one array, you must be sure that your host’s operating system (OS) supports multiple Logical Unit Numbers (LUNs). Most operating systems (OSs) support multiple LUNs, or can be enabled to. If yours does not, the host sees only one array at LUN 0. Refer to Setting the Host System HBA to Multiple-LUN in the DuraStor Installation and User’s Guide.
  • Page 13 5 Enter a name for the array. You can enter up to 27 characters (A-Z and 0-9), one at a time. ↑ ↓ to choose a character and then press Enter. Repeat until the name is complete, then press Enter. Note: If you do not want to name the array, skip this step by pressing Enter.
  • Page 14 9 Choose the number of disk drives in the array, excluding spares, then press Enter. The Select Drives screen appears. If you are using active-active mode, the Select Drives menu includes all available disk drives (those that are not members of an array and are not assigned as dedicated or pool spares) on both controllers.
  • Page 15 If the array you are creating is a RAID 3, RAID 4, RAID 5, or RAID 50, the Chunk Size screen appears. If you are creating a different type of array, skip to 14 Choose the chunk size, then press Enter. Chunk size is the amount of contiguous data that is written to an array member.

  • Page 16: Creating A Multiple-Partition Array

    Note: Most OSs, such as Windows NT 4.0, require you to reboot the host system to see the new array. NetWare v3.12 and later can recognize new devices by typing the command SCAN FOR NEW DEVICES at the console prompt. Other OSs might have similar features. Creating a Multiple-Partition Array You can create an array that has more than one partition.
  • Page 17 7 Choose the RAID level, then press Enter. (You can choose from RAID 0, RAID 3, RAID 4, RAID 5, RAID 50, VOLUME, or MIRRORED. Note: A RAID 10 array is automatically created when there are more than two disk drives in a mirrored array. If you selected RAID 50 as the array type, the Pick RAID 50 Array Size screen appears.
  • Page 18 11 Choose a disk drive to use as a dedicated spare, then press Enter. Repeat, if you are using multiple dedicated spares. Only available disk drives (those not members of an array or assigned as dedicated or pool spares) display. You can delete a dedicated spare from the array at any time.

  • Page 21 RAID level—Array type (0, 3, 4, 5, 50, volume, or mirrored). The term mirrored is used for both RAID 1 and RAID 10 arrays. Number of drives—Number of disk drives in the array when fault-tolerant. For example, if you create a three-drive RAID 5 array and lose one disk drive, the number will still display 3.

  • Page 22: Stopping The Array Initialization Process

    Viewing Disk Drive Status You can view the following information for the disk drives in an array: Drive number—The disk drive’s sequential position in the controller’s disk drive list. Drive status—Whether the disk drive is up, down, or spare. Channel number—Back-end disk bus number. Target ID—The number assigned to each disk drive attached to a SCSI channel (also known as SCSI ID).

  • Page 23: Verifying An Array

    To stop the array initialization process 1 Press Menu, choose Controller Menu, then press Enter. 2 Choose the desired controller 3 Choose Array Menu, then press Enter. 4 Choose the array you want, then press Enter. 5 Choose Abort Initialization, then press Enter. The system asks if you want to stop the initialization process.
  • Page 24 Checking the Progress of the Array Verification You can check the progress of the array verification at any time. There are two ways to do this: Viewing Verification Status on page Select Array Menu from the System Menu. The status of the verification appears in the list of arrays. Viewing Verification Status You can view the status of the verification process while it is running.

  • Page 25: Reconstructing An Array

    Reconstructing an Array The controller automatically reconstructs redundant arrays (RAID 3, RAID 4, RAID 5, RAID 50, and mirrored) if an array becomes critical and a proper-size spare disk drive is available. An array becomes critical when one or more member disk drives fail. If a reconstruct does not start automatically, it means that no valid spares are available.
  • Page 26 Table 2-2. Disk Drive Additions by RAID Level RAID Level RAID 0 RAID 1 (mirrored) Volume Set RAID 10 RAID 3, 4, or 5 RAID 50 If you are expanding a multiple-partition array, you add free space at the end of the array. Note: Once you start expanding array capacity, you cannot stop it.

  • Page 27: Changing An Array Name

    Checking the Progress of the Array Expansion You can check the progress of the array expansion at any time. There are two ways to do this Viewing Expand Status on page Select Array Menu from the System Menu. The status of the expansion appears in the list of arrays. Viewing Expand Status You can view the status of the expansion process while it is running.

  • Page 28: Changing Array Ownership

    Changing Array Ownership If you are using active-active mode, you can change the ownership of any array between controllers. You might want to change ownership if you plan to replace or repair one controller. Changing ownership lets you continue using an array without interruption, and makes the array visible on the controller you change it to and not visible on the original controller.
  • Page 29 An array is offline because a disk drive is failing, you have no data backup, and you want to try to recover the data from the array. In this case, the Trust Array Function may work, but only as long as the failing disk drive continues to operate. Before you can use the Trust Array Function, you must enable it in the Option Configuration Menu.

  • Page 30: Deleting An Array

    Note: If the array does not come back online, too many members may be offline or the array may have additional failures on the bus or enclosure that Trust Array Function cannot fix. Deleting an Array You can delete an array when you no longer need the array or you need the disk drives for another use.

  • Page 35: Changing A Partition Lun

    Changing a Partition LUN You can change the LUN assigned to a partition as it appears under the controller’s target ID from the host system’s point of view. The change takes place immediately; however, you may need to reboot the host system to see the partition at the new LUN. Note: You cannot change the partition’s LUN to one that is already in use.

    Resetting Overall Statistics You can reset all of the overall statistics back to zero, which you may want to do if you are monitoring performance. Note: Resetting overall statistics also resets the statistics for each individual partition. See on page 2-23.

  • Page 43: Managing Spares

    Managing Spares DuraStor RAID controllers automatically reconstruct redundant (fault-tolerant) arrays (RAID 3, RAID 4, RAID 5, RAID 50, and mirrored) if an array becomes critical and a proper-size spare disk drive is available. An array becomes critical when one or more member disk drives fail.

  • Page 44: Adding A Dedicated Spare

    Adding a Dedicated Spare You assign dedicated spares to a specific array. If a member disk drive in the array fails, the controller uses a dedicated spare to automatically reconstruct the array. You can add dedicated spares to mirrored and parity arrays as you create the array or afterward. You can assign up to four dedicated spares to an array.
