How does VNX allocate luns when you set it to auto?
I know in the past with CX it would just alternate between A and B if you asked for 10 luns, so it was evenly distributed. Partner is telling me this isn't the case with VNX. Can someone elaborate? Pointing to documentation would help greatly as well.
Thanks,
Andrew

From the HELP in Unisphere:
Default owner of a LUN
The default owner is the SP that assumes ownership of the LUN when the storage system is powered up. If the storage system has two SPs, you can choose to create some LUNs using one SP as the default owner and the rest using the other SP as the default owner, or you can select Auto, which tries to divide the LUNs equally between SPs. The primary route to a LUN is the route through the SP that is its default owner, and the secondary route is through the other SP.
I created 10 LUNs with Auto selected

Thanks this is how I knew it always worked with CX, VNX, but I had heard different from a partner so was just checking. Thanks!
