Hi

we have the situation that data on one lpar on many hdisks should be
moved to another physical volumes in an other SAN box (disk
performance). So we think about using the migratepv command to move the
data. Would be the following steps correct ?

1. Attach needed new LUNs to both VIO servers
2. Map these new LUNs from both VIOs to the lpar and add them to the
volumegroup (extendvg ...)
3. Run migratepv command online to move data from old hdisk to new
hdisk (migratepv hdisk<source> hdisk<target>
4. Test if the migrated data are useable in the right manner
5. If all is ok, remove the old hdisks from the volumegroup (reducevg)

Are these steps practicable ?

Thx in advance
