  • Page 9: Introduction

    Adaptec Arrays An Adaptec array is an array that was set up using Adaptec’s array software (see The Adaptec Array Software on page 1-4). Adaptec’s array software lets you create up to four nonbootable arrays of SCSI disks, offering several array types.
  • Page 10 Creating and Managing Arrays RAID 0 (Striped Disks) In a RAID 0 array, data is distributed, or striped, across the disks in the array. The array appears to the server as one large disk with a cap- acity approximately equal to the combined capacity of the physical disks.

  • Page 11: Number Of Disks In An Array

  • Page 12: Mixing Disks From Different Manufacturers Or With Different Capacities

    Mixing Disks on Different RAID Adapter Channels An AHA-3980 RAID adapter has two channels: A and B. An AHA-3985 RAID adapter has three channels: A, B, and C. Each channel acts as an independent RAID controller, implementing a separate SCSI bus (for more information on the AHA-3980 or AHA-3985, see the AHA-3980/3985 User’s Guide).

    AHA-3980 and AHA-3985 RAID adapter kits include Adaptec CI/O (the single server version). If you purchased the RAID adapter sepa- rately, you can obtain Adaptec CI/O by calling the sales order line at the number listed on page ii. System Requirements...

  • Page 21: Gray Menu Options

    Gray Menu Options Gray menu options are not available to you, usually because they do not apply to the chosen array. If an array has no failed drives, for example, the Reconstruct Functions option on the Main menu is gray, because no drives need to be reconstructed. Similarly, the Convert RAID Level option is always gray for a mirrored array, because you cannot convert a mirrored array to another format.

  • Page 23: Setting Up The Initial Arrays

    Note: If you have not yet installed the NetWare drivers for the AHA-3980/3985, do so before you set up the arrays (see AHA-3980/3985 User’s Guide for instructions). When you install the drivers, you also install the RAID utilities—in the DOS directory containing the server.exe file.

  • Page 26 To cancel the last selection, press the Delete key. To cancel an earlier selection, press the Delete key until the disk name no longer appears in the Adaptec Array # box (this cancels all disk selections back to that point, so you must reselect those disks you still want in the array).
  • Page 27 If the array is mirrored or RAID 5 and you have a disk left, a prompt appears, asking whether you want to choose a spare disk: If you do not want a spare: Type n and continue with step 10. To select a spare: Follow these steps: At the prompt, type y.

    Creating and Managing Arrays array utilities to that directory. If the sys:system directory does not exist, you must create it later and copy the utilities to it (see Installing the Array Utilities in the sys:system Directory below). When the Administrator utility finishes, it prompts you to press any key to continue.

  • Page 31: Formatting Arrays

    Formatting Arrays Whenever you create an array or redefine disks (other than spares) in an existing array, you must format the array. To do so, you can Perform a low-level format, or Initialize the array with zeroes Both types of formatting accomplish the same things: they erase all existing data on an array, and format the array for the specified array type.

  • Page 32: Choosing The Data Block Size

    Creating and Managing Arrays Check with your vendor or your drive documentation to learn how your drives handle low-level formatting. If you find the low-level formatting speed is acceptable to you, low-level formatting is the better choice. Choosing the Data Block Size When formatting arrays other than RAID 1 arrays, you must choose the size of the data blocks that will be striped across the array.
  • Page 33 Select Initialize Array to Zero or Low-Level Format. Caution: Remember, formatting or initializing an array erases all data on the array disks. If the array disks contain data you want to keep, be sure to back them up before you format the array! A menu of block sizes appears (this menu does not appear if the array is a mirrored array with only two drives).

  • Page 34: Canceling Formatting

    Creating and Managing Arrays completed. For low-level formatting, it displays the elapsed format- ting time. To display this information, press Alt-Esc until the Adaptec RAID Format Utility screen appears. You can display this screen even if you exit the Administrator utility. Note: After you format an array, view the status screens for that array to verify the array configuration.

  • Page 35: Monitoring Array Performance

    With the Administrator util- ity, you can view these performance statistics at the server console. If you have the Adaptec CI/O software, you can also view the statistics at a remote workstation. The Administrator utility also monitors arrays for problems, such as failed drives.

  • Page 43: Managing Arrays

    Managing Arrays Use the Administrator utility to routinely verify arrays and test spare disks, and to perform such nonroutine tasks as reconstructing data on replacement disks and reactivating off-line arrays and spare disks. The utility’s Scheduler function lets you schedule most of these tasks to run automatically at a specified time or interval.

  • Page 44: Assigning A Priority

    Creating and Managing Arrays Verification runs in the background, so you can continue your work while verification is under way. Assigning a Priority You assign verifications a priority on the server. The priority, which can be 0 through 9, determines the proportion of verification I/O operations relative to other system I/O operations.

The Configuration screen shows the percentage of verification completed While Verify runs, the logical block addresses (LBAs) of any repaired data blocks appear onscreen.

  • Page 46: Changing The Priority Of A Verification In Progress

    Creating and Managing Arrays Changing the Priority of a Verification in Progress If a verification is slowing other server operations unacceptably, you can lower the priority of the verification on the server. Conversely, you can speed a verification by increasing its priority. Change the priority at either the Verify menu or at the screen show- ing the Verify status bar: From the Verify menu, select Change Priority.

  • Page 47: Reconstructing The Data Immediately

    data is copied from the other disk in the mirrored pair. Data is recon- structed in the background, allowing you to continue working. Note: If your drive box requires that all host adapter activity stop while you replace a drive, use Hot Swap Pause. For details, see Pausing Host Adapter Activity When Replacing Disks on page 6-12.

  • Page 48: Reconstructing The Data At A Scheduled Time

    Creating and Managing Arrays The Reconstruct utility also tracks reconstructions, displaying a sta- tus bar that indicates the percentage completed. To display the sta- tus bar, press Alt-Esc until the status bar appears. Reconstructing the Data at a Scheduled Time Because reconstructing data may slow a system, you may want to schedule this operation for a time when system use is light.

  • Page 49: Reactivating An Off-Line Array

    Reactivating an Off-line Array An array goes off-line if the power fails or if someone removes a sec- ond disk when one has already been removed. To reactivate an off- line array, follow these steps: If the system has only one array, skip to step 2. Otherwise, from the System menu select the array you want to reactivate.

  • Page 50: Scheduling Tasks

  • Page 59: Selecting Different Disks For The Array

    Caution: Make sure your data is backed up before you refor- mat the array! If the number of disks in the array is not suitable for the new RAID level, you must reselect disks for the array and then format the array. For instructions on selecting disks, see the next section, Selecting Dif- ferent Disks for the Array.
