Solaris + Clariion. Max LUNs.
Gurus,
I have an EMC clariion CX600 hooked up to an SAN running Solaris 8 and 9 boxes. We are getting close to 256 LUNs, and noticed that the /kernel/drv/sd.conf only defines LUNs 0-256 ie: last line: name="sd" parent="lpfc" target=17 lun=255; (There are 2 HBAs, 2 switches and 2 SPs, making 4 paths to each disk). All disks are presented to all hosts with VxVM 3.5 controlling which dg is presented where. Given that the Clariion can make 1024 LUNs, is this a hard limit, in Solaris, or can it be surmounted? If not: This is a "production" network for a software development company, so we need the ability to move databases between boxes to simulate different environments.... Solaris 8, 9... 2 proc server, 8 proc server etc etc. Databases vary wildly in size, and we currently have 6TB cut up into LUNs of 13GB and 54GB in order to create any sized DB. I am still learning how to drive the Clariion, and the low level stuff I do using the Navisphere GUI. However, if somebody can let me know what commands I need to consider to create snapview sessions and snapshots, present and un-present LUNs to various boxes, and make inquiries over what what is presented where, I'll go back to the manuals and try and put this in some form that the operators can handle. (I have over 2000 pages of CLI documentation. A few pointers would really help!) Thanks in advance Matt |

Given that the Clariion can make 1024 LUNs, is this a hard limit, in Solaris, or can it be surmounted? Can you have the Clariion produce the luns on a separate "target"? It might need to be another FA or another WWN which the HBA driver would map to a target. -- Darren Dunham Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
