HACMP and disk management

[madra]

We're due to replace our DS4700 with an IBM SVC

This will entail moving from hdisk devices to vpath devices.

Which is the best way, outside of HA or within HA ?

At the moment we're unsure of the exact steps to do this within side HACMP. Cluster Data path management or Replace a Disk etc...

Any advice would be grateful.

thanks,

You should use SDDPCM if you can, still uses hdisks,
see

http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/FLASH10587,

and HACMP generally uses the vg for failover, and since you are still using hdisks.
I would think that disk replacement would be the same.
