Solaris

had this one controller tray 12 disks and one expansion tray 12 disks, hard-linked to a v240 system..

for some reasons, only 6 drives from the controller tray are on..and 6 drives from the expansion tray are on...

I can run sccli into the array.. none of the show commands come up with anything meaning..except "this config is not supported by this RAID controller .."

The firmware on the 3510FC is updated, I am running sccli 2.4, the latest
release..

are you sure the storage+expansion is cabled correctly?

I did this cabling according to the best practise of SE 3510FC document..

one dual controller tray + one expansion tray...

I noticed the lights on the 6 drives for each tray is off for some strange reason when operating...

here is the connection I see:

FC2 (1st controller) ---> bottom right FC port, expansion tray
FC3 (2nd controller) ---> bottomr left FC port , expansion tray
FC3 (1st controller) ---> v240 host
FC2 (2nd controller) ---> 420R host

I am almost 99% of this cable connection is OK, since at one point I was able to see the disks on both hosts, using vxvm, now if I do a path listing to some disks, it is telling me invalid, about half of the total hosts. cfgadm tells me half of them are not connected..

I am curious what might be the problems...
