HP/Apollo division should be paying me commissions for user-support! OK, this comes from the Update to Domain Series 2500 Owner's Guide, order number 017934-A00 ... Use the regular "invol" program to format the disk. If you are adding a disk to a system which is already up and running, you can do this online using /etc/invol (/com/invol is a link to /etc/invol for you Aegis users). Use option 1 -b to initialize the disk with BSD-style ACL's. If you want to boot from this disk, then use option 8 to create an OS paging file after you do option 1. Invol prompts for the disk to use in the form "w:" ie. to init the second disk on the first controller, you would use "w0:1" -- to init the first disk on the second controller (ie. the 3rd disk in the system as each controller can handle two disks), you would use "w1:0". Be aware that the "controller" and "unit" have different meanings for ESDI (ie. DN3xxx/4xxx and DN10000) disks and SCSI disks. With the ESDI disks, "controller" is what you think it means -- the number of the disk controller board, ie. 0 or 1 -- and "unit" is the number of the disk attached to a particular controller, ie. 0 or 1 again. With SCSI disks, "unit" is always 0, and "controller" is the number of the SCSI target ID which is set on the disk (i.e 0 to 6 -- 7 is reserved for the CPU's target ID). Once you have involed the disk, you can create the the Unix device file with the command: /etc/mkdsk W where and are the same as they were in the "invol" command, and is the number of the logical volume you created when you initialized the disk ("invol" will allow you to partition a disk into 1 or more logical volumes). For example, to create the Unix device file for the 1st logical volume of the second disk (ie. unit 1) on the first controller (ie. controller 0) you would use the command: /etc/mkdsk W 0 1 1 To create the device file for the 2nd logical volume of the same disk, you would use /etc/mkdsk W 0 1 2. Once you have created the device file, you make an emptry directory for a mount point, just as in a native Unix system, using /bin/mkdir (ie. /bin/mkdir /moint_point_for_new_disk) and then use the regular Unix "mount" command to mount the disk using the device file you just created (ie. /etc/mount /dev/whatever_mkdsk_reported_as_the_device_name /mount_point). -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter.mit.edu@eddie.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)
