Hi All
Can you help with a proposed config for a customer.
They want to provide access to a single A1000 from two systems. The proposal
is to connect both systems via SCSI diff controller to the same ports on the
A1000. Then allocate two LUN's on the A1000, one which will be used by each
system. In the event of system failure, the other one can access both LUN's
and access all of the data.
The problems as I see it are as follows, any suggestions/experiances will be
well received.
1) The second system requires that the SCSI id of the diff card be set to a
value different to 7 of the first system as they are all connecting to the
same port on the A1000. Anyone help with changing this via the OBP?
2) There is an assumption that the setup of the A1000 into two LUN's is
possible and that they are accessible as if they are two separate disks to
the SCSI I/F. IE you can see two disks if you use probe-scsi-all. I have not
setup an A1000, so am unsure if this is possible.
Thanks for your replies.
Peter
