2. Q&A

• Q:DoweneedtomanuallycreateConsistencyGroupsonVPLEXandRPtoselecttheminViPR?

A:YoudonotneedtomanuallycreateanythingoutoftheVPLEXorRP.ViPRwilldoeverythingforyou.

YoudoneedtocreateCGinViPR.Aslongas“Multi-volumeconsistency”VPoolparameterischecked,than

youhavetheabilitytoselecttheCGinViPR.ViPRgoesouttoaVPLEXandRPandcreatenewCGsandadd

appropriatevolumestothem.

• Q:CanwechangeVPooltoMetropointconfiguration?

A:YeswecanchangeVPoolwith“AddMetropointprotection”option.OnelegwithCDPwillbechangedto

anotherVPoolwith2legswithCDP.

• Q:CanwechangeVPLEXMetrovolumetoMetropointCRR(3-site)protectedvolume?

A:Yes,butyoucan’tjumpdirectlyfromVPLEXvolumetoaMetropointvolume.IntermediateRPprotection

stepisneeded.

• Q:Canwehavea3rdMetropointprotectedsitewhichshouldbeCRR?

A:Shouldbechecked.Notsureifthatissupportednow.

• Q:IsRP/VEissupported?

A:RPVirtualEditionisnotsupportedbyViPR.

• Q:CanweingestexistingMetropointconfigintoViPR?

A:No,wecannot.But2.4supportsVPLEXvolumesingestionbothexportedandnotexportedtogetherwith

associatedback-endvolumes.WehopetoingestRPprotectedvolumesinthelaterreleases.

• Q:CanweexpandaJournalvolume?

A:No,wecan’texpandaJournalvolumewithViPRv2.4.Addingnewvolumeistheonlyoptionavailable

now.

• Q:AllJournalvolumesaredeletedbyViPRonlyafterthelastvolumeinCGisdeleted.Canwe

manageJournalvolumesfromUnisphereoutsideofViPRtomanagestoragecapacity?

A:Weshouldn’tmanageJournalvolumesoutsideofViPR.Thereasoniswecan’tidentifywhichJournal

volumeisusedbywhichproductioncopy.DataisspreadofallJournalvolumes.Thatiswhywedelete

Journalvolumesonlyafterthelastvolumeisdecommissioned.ThatwhywekeepallJournalvolumestillthe
