We are having a problem with all of our servers. 4 server cluster we add a LUN with a ID above 7 scan the storage adapters but the LUN will not be seen by any of the servers.
If we create another LUN with an id 5 or anything below 7 and rescan the servers all see LUN id 5 on first-second rescan. The strange thing is the other LUN with a ID above 7 we added earlier is also seen. We are using 3.02 and patched up to date the servers have the advance setting - DiskMaxLUNS set to 256 the default. Help
are you sure that masking/zoning is OK ?
Can you see the luns in hba bios?
