Can you explain: Why block of text has disappeared from the new version of this guide?
I mean this block:
Thin-provisioned volumes require additional I/O operation to read and writemetadata to the internal disks or to the back-end storage which will also add additionalload to the IBM Storwize V7000 nodes. We therefore do not recommend the use of thesevolumes for high performance applications, or any workload with a high write I/Ocomponent."

More than happy to clear that up. It is subject to revision at any time and this text might have given some people the wrong impression, we like to clear things like that up as soon as possible. You raise a good point that people should always ensure that they have the most current version.

Please clarify conflicting statements:
Usage of Remote Copy target volumes as Remote Copy source volumes is not allowed. A FlashCopy target volume can be used as Remote Copy source volume and also as a Remote Copy target volume.
You can use Remote Copy target volumes as Remote Copy source volumes. A FlashCopy target volume can be used as Remote Copy source volume, as of Version
6.2.0. There are additional restrictions outlined in Table 11-5 on page 447.
