xp1024 Microcode upgrade

When performing an online upgrade of the MC on an xp1024 using Alternate SCSI Path mode is the state of a LUN lost when rebooting the MP that controls the CHIP port that the LUN is presented on?
I know that it is possible to reset a CHIP port from the SVP to release any SCSI RESERVEs etc that might exist on the LUNs on that CHIP port.
However, Im not sure if the state of the LUN is stored in shared memory and not lost when MPs are rebooted during an MC upgrade.
