MSA2324i Reset snapshot removes LUN map

We're trying to utilise the snapshot feature but haveing problems scheduling a reset. If I make an explicit map and perform an immediate reset of the snapshot everything works as expected; I can go back to the host and mount the volume etc.

The problem is when I schedule the reset to happen, the LUN is reset. The event log also confirms that something is triggering this to happen;

Schedule reset of snapshot is complete here but LUN map was lost: 2011-01-19 09:45:40 A3200 221 Reset of a snapshot completed. (master volume SN: 00c0ffd8ba9900001ea0364d01000000, snapshot SN: 766430325f763030325f536e61704c55)
LUN IS RESET HERE: 2011-01-19 09:45:04 A3199 205 A mapping or masking operation for a volume was performed. (volume: vd02_v002_SnapLUN92, SN: 00c0ffd8ba9900001ea0364d01000000) (channelBitMap: 0x0, access: read/write, LUN: 0)
