A questions came up within my team regarding some VVs that we may have forgotten to tune when we added additional storage. How can we validate whether a VV is properly striped across all drives of a certain class or not? |

I am not aware of a way to do this other than physically collating all the LD's used for each VV and checking that way. I can't imagine that would be practical. What method did you use to restripe? Typically, I add the disks. Create a new CPG(s) across all the disks. Migrate all the my VV's over to those disks. |

What I think happened, though, was that they got the new storage in and wanted to immediately allocate it to a new system, so they created a new CPG and setup new VVs against it. So, basically, we're trying to recollect if we ever went back to the older VVs to tune them. If there is no practical way to validate that, I'll just have them retune them alltogether, just to be sure. Thank you. |

The GUI used to have graphic chart that helped with this, in fact that is what the logo above is made from. I can't seem to locate this feature in the current IMC. |

To turn back on the layout tab, you have to go to Edit > Preferences, and then there's an option on the Advanced tab called "Show Provisioning Layout tab." |

Thanks Steve! So with that layout tab turned on, you can select a object like a VV or CPG (or shift click multiple objects), and visually see a map of what chunklets on what disks are used. |
