However, in response to customer requests, Iomega may provide some limited information and/or instructions for unsupported systems at the assumed risk of the user.

Please use the following steps to install your Jaz® drive on a Sun® Workstation.


Operating systems that support Jaz drives:

The following operating systems support the Jaz drives when using the operating systems built-in drivers.

    Note: Do not format a Jaz disk using any of the operating systems listed below.

The Jaz drive is supported on the following operating systems using the built-in drivers, which are not provided nor supported by Iomega. Jaz disks cannot be formatted using these Operating Only standard, non-write protected disks can be used.

  1. SunOS 4.1.1
  2. SunOS 4.1.2
  3. Solaris™ 2.0

STEP ONE - Set the SCSI ID Switch on your Jaz drive

    Note: Be sure to select an unused setting.

  1. SunOS 4.1.1, 4.1.2, or 4.1.3, use SCSI ID 0, 1, or 2.
  2. Solaris 2.0, SCSI IDs 3 & 7 are reserved, use any other unused SCSI ID setting.

STEP TWO - Attach the Jaz Drive to your SCSI adapter or chain and create a Device Entry Point (for Solaris 2.0 only)
  1. Attach the Jaz drive.

  2. Start your SPARCstation™.

  3. At the OK prompt enter boot-r.


STEP THREE - Entries for format.dat

    Enter the appropriate entry into the /etc/format.dat file. Use the system editor and be careful not to change other file entries. The entries are case sensitive!

    Solaris 2.0;
    disk_type="Jaz 1GB"\ 
     :ctlr=SCSI\
     :ncyl=1018:acyl=2:pcyl=1020:nhead=64\
     :nsect=32:rpm=3600:bpt=16384
    partition="Jaz 1GB" 
     :disk="Jaz 1GB":ctlr=SCSI\
     :2=0,2084864
    SunOS 4.1.1, 4.1.2, 4.1.3 (for SunOS 4.1.1, replace the controller type SCSI with MD21)
    disk_type="Jaz 1GB"\ 
     :ctlr=SCSI\
     :ncyl=1018:acyl=2:pcyl=1020:nhead=64\
     :nsect=32:rpm=3600:bpt=16384
    partition="Jaz 1GB"\ 
     :disk="Jaz 1GB":ctlr=SCSI\
     :c=0,2084864

STEP FOUR - Data Disk Preparation Procedure
  1. Insert the correct Iomega disk in the Iomega drive prior to booting the SPARCstation.

  2. Run the SunOS format program at the # prompt type: format

    Note: In the following examples, X represents the sd number shown on your monitor for the drive that contains the working disk.

  3. Select the sd number related to the drive that contains the disk you are formatting. If the disk has never been formatted, the program should enter the Drive Type menu. Select the appropriate disk type from the list.

  4. Use the partition sub-command to choose the partition information.

  5. Use the print option to verify the existence of the C partition.

  6. Use the label sub-command to write a label on the disk.

  7. Use the quit command twice to exit the format program.

  8. Run the newfs utility to make a file system on the disk. At the # prompt type: newfs -v /dev/rsdXc


STEP FIVE - How to use a Jaz disk
  1. After the file system has been placed on the disk, you can mount it into the UNIX file system. (Replace mount_point with an appropriate mountable directory eg. /mnt). At the # prompt type: mount /dev/sdXc /mount_point

  2. When you are through using the disk, it can be removed from the UNIX file system. At the # prompt type: umount /dev/sdXc or: umount /mount_point

  3. To check the file system, make sure the disk is not mounted and use the fsck command. At the # prompt type: fsck /dev/rsdXc
