20EE000A Pointer to Operating
System not found in
non-volatile storage
Values normally found in non-volatile storage that point
to the location of an Operating System were not found.
This can happen for two reasons, either your installed
Operating System doesn't support storing the values or
some event occurred that caused the system to lose
non-volatile storage information (drainage or
replacement of the battery). If you are running AIX,
this information can be reconstructed by running the
bootlist command specifying the device that the
Operating System is installed on. Please refer to your
AIX documentation for the exact syntax and usage of
the bootlist command.
In order to boot the Operating System so that the
above mentioned values can be reconstructed, power
the system down and power it back up again, this
should cause the system to look for the Operating
System in the devices contained in the custom boot list
or in the default boot list, depending on the condition of
the system. If this is not successful, modify the Boot
Sequence (also known as boot list) to include devices
that are known to contain a copy of the Operating
System. This can be accomplished by using the
System Management Services Menus. For example,
select a hard disk known to have a copy of the
Operating System as the first and only device in the
boot sequence (boot list) and attempt to boot again.
20EE000B The system was not
able to find an
Operating System
on the device list
that was attempted.
Modify the Boot Sequence (also known as boot list) to
include devices that are known to contain a copy of the
Operating System. This can be accomplished by
powering down the system, powering it back up again,
and using the System Management Services Menus.
For example, select a hard disk known to have a copy
of the Operating System as the first and only device in
the boot sequence (boot list) and attempt to boot
again.
SCSI Device errors
SCSI device error notes:
1. Before replacing any system components
a. Ensure that the controller and each device on the SCSI bus is assigned a unique SCSI ID.
b. Ensure SCSI bus is properly terminated.
c. Ensure SCSI signal and power cables are securely connected and not damaged.
2. The location code information is required to identify the ID of SCSI device failures as well as to
indicate the location of the controller to which the device is attached.
