I am looking for the 3PAR CLI method to map an already_create VV to another initiator host. In VSA i was able to do the same as follows: CLIQ>getVolumeInfo volumeName=volume-b0bd9277-1add-4b22-b0c2-18a14823268f CLIQ>assignvolume volumeName=volume-b0bd9277-1add-4b22-b0c2-18a14823268f initiator=iqn.1993-08.org.debian:01:9095ec748e76 Discover from initiator: #iscsiadm -m discovery -t sendtargets -p 10.16.4.205 10.16.4.205:3260,1 iqn.2003-10.com.lefthandnetworks:hpevsa:186:volume-b0bd9277-1add-4b22-b0c2-18a14823268f Present the LUN: #iscsiadm -m node -T iqn.2003-10.com.lefthandnetworks:hpevsa:186:volume-b0bd9277-1add-4b22-b0c2-18a14823268f --login How to do the same thing in 3PAR cli . I aksed many ppl , everyone says they have not tried via CLI. Instead use SSMC. Is it possible via 3Par CLI. If so, how? |

See the "createvlun" command, CLI guides below. https://support.hpe.com/hpsc/doc/public/display?docId=c04204279 https://support.hpe.com/hpsc/doc/public/display?docId=c04204251 Ensure you aren't exporting the same volume to none clustered hosts otherwise there's the potential for writes from different hosts to corrupt the volume. |

Hi JohnMH, Thank for the reply. I saw this command createvlun. I am new to 3par and trying to understand the folowing things. I have done the following: Created a VV from oepnstack cinder in my 3PAR. <snip> FTC-R25-S-2851 cli% showvv -showcols Name,Comment osv-vQDRqhUSQ.aJVCOwajcJuw Name Comment osv-vQDRqhUSQ.aJVCOwajcJuw {"display_name": "ubuntu-20GB-volume", "type": "OpenStack", "name": "volume-bd00d1aa-1512-43e6-8954-23b06a3709bb", "volume_id": "bd00d1aa-1512-43e6-8954-23b06a3709bb"} OR FTC-R25-S-2851 cli% showvv osv-vQDRqhUSQ.aJVCOwajcJuw --Rsvd(MB)--- -(MB)- Id Name Prov Type CopyOf BsId Rd -Detailed_State- Adm Snp Usr VSize 14142 osv-vQDRqhUSQ.aJVCOwajcJuw tpvv base --- 14142 RW normal 768 1024 4096 19200 </snip> I also have mapped my host from 3par: FTC-R25-S-2851 cli% showhost ubuntu Id Name Persona ------------WWN/iSCSI_Name------------ Port 937 ubuntu Generic iqn.1993-08.org.debian:01:9095ec748e76 1:2:2 So if i need to map this VV osv-vQDRqhUSQ.aJVCOwajcJuw to ubuntu host with IQN iqn.1993-08.org.debian:01:9095ec748e76, what should i do: As per my understanding, i should create a vlun using createvlun command to map the VV osv-vQDRqhUSQ.aJVCOwajcJuw to the newly created VLUN. something like FTC-R25-S-2851 cli% createvlun osv-vQDRqhUSQ.aJVCOwajcJuw 12 ubuntu Where in the above command ubuntu is my host; osv-vQDRqhUSQ.aJVCOwajcJuw is my already available VV 12 is the newly created VLUN. Any pointers is highly appreciated. Regards, Novel |
