3.5 Checking Peripherals
LDEV 1 Disk Minimum Capacity
LDEV 1 requires a minimum capacity of 500 MBytes. As of Release 5.0, you cannot use the
older HP7933 or HP7935 disk drives as LDEV 1 (the system disk).
When you update to MPE/iX Release 6.5, you will be unable to use CIO or fiberlink drives
anywhere on the system. It is recommended that you disconnect all unsupported devices
before updating.
To identify your LDEV 1 device, use the DSTAT ALL command to determine the logical
device numbers of configured devices.
1. From either the terminal or console for each system:
:DSTAT ALL
2. If you are on an operating system older than 5.0, and if the device configured as your
LDEV 1 is an unsupported device (such as HP7933 or HP7935), you must replace your
LDEV 1 device with a supported device. Contact your HP representative to schedule
installation of the replacement disk drive. See further instructions in the 5.5 System
Software Installation Manual for Release 5.5.
3. If the device configured as your LDEV 1 is supported, proceed with “LDEV 1 Disk
Maximum Usage.”
LDEV 1 Disk Maximum Usage
If you are using a disk drive with over 4 GBytes capacity as LDEV 1, any disk space over
the 4 GBytes is not available for use. It cannot and will not be used for system or user files.
The 9 GB disk drive cannot be used as LDEV 1.
