Looked at a V7000, but decided to get rid of IBM storage (DS4700) here. Any problems we have the answer is always upgrade firmware. Other vendors will upgrade your firmware for you. With IBM, it is up to you to determine what part numbers you have, what the current version is, what version you have, what the upgrade path is, etc.
After you have done all that, they will determine it is an SVC problem and you will have to call SVC support. SVC support will then tell you to upgrade the SVC firmware.
You get the idea.
