Booting From The SRM
Placing bootable aSses on sector oriented devices is fairly straight forward. On LIF devices an
as file IYLUst be created, and on SDF and HP- UX devices a boot area must be created. For the
SRM, aSses to be booted must be placed in system files in the directory /SYSTEMS.
Because the SRM is a shared resource there are some unavoidable and peculiar behaviors that
can be exhibited if the /SYSTEMS directory changes while the Boot ROM is scanning it. During
the scanning or booting process, the order of the directory can be re-arranged, as files can
be deleted, or added. This means that the Boot ROM may show an as that does not exist
anymore, nlay
not show an as that does exist, or may never show an as that has always been
there.
If an as that does not exist is chosen to be booted, the Boot ROM will stop with the error NOT
FOUND. A reset is required to try again.
As long as
the /SYSTEMS directory is stable, which is usually the case, everything will work as
expected.
