Hi folks, I apologize in advance if this has been covered already but doing a search I wasn't able to turn up any info that's relevant to my problem.
We're currently building a low cost NAS based on the following hardware and OpenSolaris 2009.06 (all latest patches) with the HP CPQary3 driver (v2.20): - HP Proliant DL585G5 - HP StorageWorks Smart Array 6404 controller card - 4 x HP StorageWorks MSA20 disk enclosures (configured as 48 x 750GB SATA "RAID-0") The initially we deployed this system with 2 disk enclosures attached and have had no issues while we migrated the data from the old host to the new server. Once the data migration was completed we added the 2 old disk enclosures to the server. However we have encountered an issue, although all 48 disks are visible to the storage controller the operating system only sees 24 disks. I initially suspected that the expansion module that turns the 6402 into a 6404 wasn't working properly but when I did a search of the BigAdmin HCL I see that the 6400EM (the expansion module itself) is explicitly compatible (http://www.sun.com/bigadmin/hcl/data/components/details/324.html). I'm wondering if there is a special incantation that I am not aware of that is required to make the additional 24 disks visible to the operating system. I have already performed a reconfigure boot as well as running 'drvconfig' and 'devfsadm' in an attempt to try everything I could think of. I'm going to open a ticket with HP and see if they can confirm that all 4 channels are supported on the 6404 but I'm not sure how far I will get with that approach as HP doesn't officially support OpenSolaris. I'm fairly confident that this is not a hardware problem as I am able to see all 48 disks from a Linux rescue CD. I've considered attempting to migrate to FreeBSD but I'm not really comfortable with the stability of ZFS on 7.2 and I don't want to use 8.0 in a production environment yet. Any suggestions or help would be much appreciated. I can provide additional information on the system and configuration if it would help. cheers, Gabriel -- This message posted from opensolaris.org
