CPG growth not keeping up with ESX migration.

[woodunn]

We are currently migrating from a F400 to a 7400 and have hit a bug that HP have advised the "lab will develop (and test) a fix for this but ETA of fix (sic) is not availabe at this time.

So, what is the issue?

As we are storage migrating between arrays occasionally the migration stops and reports that the destination TPVV VLUN has run out of space.
After further investigation we found that the CPG had run out of space and not grown quick enough for the VLUN to assign growth space. This is the first environment that is being migrated so the destination array is not under load.
Growth increments is set to 128GB which was changed from 64GB when it first occurred

Anyone else had a CPG run out of space and not grow quick enough for TPVV growth?
