Symmetrix Optimizer questions
I'm trying to get Optimizer setup and have 2 questions/issues.
1. The priority for some devices shows as "Unknown". When I try to set to "Normal" and save change I get an error "The operation cannot be completed because one of more devices are unconfigured"
2. When Optimizer does swaps, will it always use DRVs within the same Disk Group as the device being swapped? Example: I have a DRV in Disk Group 1 FC15K disk group and a DRV in Disk Group 2 SATA disk group. The device being swapped is in Disk Group 1 FC15K disk group, will it ever try and use the SATA DRV? Second Example: Disk Group 1 is 146GB FC15K and Disk Group 2 is 300GB FC15K. Can a DRV in the 300GB FC15K disk group do a swap for a device in the 146GB FC15K disk group (assuming DRV is large enough)?

Hi,
I know its been long since you posted this query. Might be the issue is resolved at your end by now. But I just wanted to add in my comments on your query.
1) Check if these devices are the one's that doesnt exist in Symmetrix but still masked to the host.We need to unmask these devices from the host.
2) DRV selection doesnt depend on Disk Groups. We just need to have 2 DRV's for each size and emulation of the
volume to be swapped by Optimizer. Disk technology is also not counted here.
If its VMAX: only 1 DRV is required per swap and the DRV can be equal or larger in size than the logical device that is swapped.
