Hi, I wonder if anyone can answer this question, we are using sun Storedge 3510FC on about ten different systems, one of the setup(all but one) used three of those unit linked with 2 Gb fiber loops to see maxium of 3 x (12 x 73GB) hard drives, the controllers are dual channels to the arrays. After configuration, they all created /dev/dsk/ and /dev/rdsk/ with WWN, ie /dev/rdsk/c7t40d0s20440FBDE0Fs2. We configured one with just a single array, that's 12 drives wtih 73GB each, all devices show up in /dev/dsk and /dev/rdsk without WWN, ie /dev/rdsk/c7t40d0s2, c7t40d1s2 and etc. Both setup worked fine, they used the same hardware, same version of Solaris, even the same release date, applied the same patched, but don't know why the system with single arrary has normal device node and the others has the weird World Wide Name. I search the internet, found only one post talk about conflict Hard Drive ID on the SAN will cause that, but it will funtion as normal when addressed with the WWN node, I tried reconfigure with "boot -r" and devfsadm on the system with single arrary but not able to cause it to create WWN node, anyone know what's the real cause of this?
Thanks
