Apologies if the question has been asked before but could'nt fine a good answer to this question.

I have been asked to study the impact of changing the host group mode on a USP. Someone had accidently assigned a windows host to a unix HSD.

As per my faint memory (the last time i did this was on HP XP512) and some reading

1. Data integrity is at risk and the vendor would ask us to backup data.

2. Would need to shutdown the host so that it does not claim the LDEV's at the point of change.

Would appreciate any pointers to assist me plan this activity. I would be getting assistance from HDS, but I really appreciate the prescence of some experienced folks here on the forum.
