You DO need to create new LDEV's for these new drives if, as is presumeably
true, they were not pre-configured on your system. It is entirely possible
that they were pre-configured (by someone) - although that is not normally
done for disk drives.

Assuming you have configured them properly - with the appropriate paths and
device id's - they will only be useable AFTER you have added them to the
appropriate volume set with the appropriate volutil command, eg:

:volutil
 >newvol mpexl_system_volume_set:member99 99 100 100 (this example is for
ldev 99 - the 99 in member99 does not need to correspond to ldev no., it
only needs to be unique for that volume set.)

Yes. Make sure the SCSI addresses of the HASS enclosures are what you
believe them to be. Do not make any assumptions. You need to set the SCSI
address dip switches properly and ensure they are unique for the controller
they are attached to.

You will probably need a little flashlight to check the settings.

Before bringing the system up, check that your drives are indeed being
recognized by booting from disk, and typing ODE, then RUN MAPPER from the
ISL prompt.
