Using mknod to Set Up Device Files
You will need to have both a character device le and a block device le to
communicate with your SCSI hard disk drive on the system.
If you need to set up a device le or change the specications for an existing
one, you can use the mknod command. For example, if you wanted to add a
character device le with a bus address of 1, you could do so by entering:
mknod
/dev/rdsk/1s0 c 47 0x0e0100
To add a block device le with the bus address of 1 instead of 5, for example,
enter the following:
mknod
/dev/dsk/1s0 b 7 0x0e0100
By convention, the \1" in the device name (/dev/rmt/1s0 or /dev/mt/1s0)
corresponds to the bus address of the device.
See \Setting Up Devices Using HP-UX Commands", in the manual Installing
Peripherals for further information on device les.
Formatting Your Disk
Since these disks are pre-formatted, you do not need to run mediainit.
Building a File System on Your Disk
8
The newfs command is a \front end" command that automates the use of
mkfs in order to build a le system on the new disk. newfs looks up the type
of disk on which a le system is being created in the disk description le
/etc/disktab and calculates the appropriate parameters to use in calling
mkfs. This call builds the le system, and installs the necessary bootstrap
programs in the initial 8192 bytes of the device.
The disktab entries for these disk drives are under the following names:
A1440A is listed as: QUANTUM PD210S
A2075A is listed as: QUANTUM PD425S
A1443A is listed as: MICROP 1588T
A2076A is listed as: MICROP 1528
