Using the GUI to Create a Volume

Toprovidestoragespacetoendusers,youcreatestandardvolumesthatuserscanthenaccess

fromhostcomputers.

Beforeyoucreateastandardvolume,youneedtounderstand:

• Volumeattributesandgroupwidedefaultsettingsofthegroupapplytoavolume.

• Volumesecurityandaccesscontrols.Inparticular:

– Theconditionsacomputermustmatchtoconnecttothevolumeanditssnapshots.Spec-

ifyaCHAPusername,IPaddress,oriSCSIinitiatorname.Thisinformationgenerates

anaccesscontrolrecordthatappliestothevolumeanditssnapshots.

– Permissionforthevolume,eitherread-write(default)orread-only.

– Whethertoallowordisallow(default)accesstothevolumeanditssnapshotsbyini-

tiatorswithdifferentiSCSIqualifiednames(IQNs).

• Risksandbenefitsassociatedwiththinprovisioningbeforeapplyingthisfunctionalitytoa

volume.

• Ifcreatingthevolumeexceedsthecapacityofthepool,freepoolspacehasanegative

value.Reducethevolumesize.

Ifyouenablethinprovisioning,youcanadjustthedefaultsettingsforthethin-provisioned

volumeattributes,whicharebasedonapercentageofthereportedsize.

Tocreateastandardvolume,usetheCreateVolumewizarddescribedinthenextsection.
