Toasters, Sorry to open an old thread but I have a related question. I have an F820 with 8 FC9's (56 disks) (7x36) attached on one FC-AL loop. I want to add a DS-14 (14x144) with an LRC for which I have a second HBA to accommodate the DS-14. The 820 literature indicates a max of 56 disks per loop, max two loops, and a max capacity of 3Tb. With my proposed config I will be at 4Tb (2 per loop) but only 14 disks on the second loop. Is it a disk limit or a file system size limit? Can I proceed with my proposed addition?
Rahul, How many FC9 shelves did you add?
Thanks, Jamie

Sure, this will work. You've got 2 options:
1) The FC9 shelves can reside on their own loop. This assumes you have a copper HBA (and you can't use the one on your 740, it's a different one, the one supported on the F820 has a GBIC on it, that's your clue).
2) The FC9 shelves can go on the same loop as the DS14 shelves as long as the DS14 shelves have LRC modules and not ESH modules. You can't mix LRC and ESH in the same loop. The rule here is when assigning shelf IDs, give the FC9 shelves the lower numbers in the loop and the DS14 shelves the higher numbers. This way you will avoid conflicts.

Hi
We have a old filer 740 with fc9 disk shelves attached to it
We want to swap 740 with 820 head and attach 1tb ds14 shelf to it along with fc9 shleves
Will FC9 shelves work with 820 ?
How can I go about it
Regards, Rahul
