https://community.hpe.com/t5/disk-enclosures/optimize-autoraid-12h-workload/m-p/2666503#M4072 Hello,<BR /><BR />If I understood correctly, you are asking why the VG is not spread out along the 8 LUNs evenly.<BR /><BR />When you create a LUN on the AutoRAID 12H, ALL the disks are used and striped accordingly. No matter how large the LUN is, all the disks are used.<BR /><BR />Then of course there is the issue of RAID 0/1 and RAID 5 migration. How many disks does your AutoRAID have? And what capacity do each disk contain?

Then created one VG on system with 8 LUN's ( may be have mistake before ). And created 2 LV on this VG, one for 79GB ( /data ) and one for 8GB ( /ap ) . <BR /><BR />Question, why not the disk work loading balance on those disks ( 8 LUN's)?<BR />The massive disk utility on particular disks.<BR /><BR />Thank in advance.<BR /><BR />Jack Fan Mon, 18 Feb 2002 11:06:44 GMT https://community.hpe.com/t5/disk-enclosures/optimize-autoraid-12h-workload/m-p/2666502#M4071 Jack Fan 2002-02-18T11:06:44Z https://community.hpe.com/t5/disk-enclosures/optimize-autoraid-12h-workload/m-p/2666503#M4072 Hello,<BR /><BR />If I understood correctly, you are asking why the VG is not spread out along the 8 LUNs evenly.<BR /><BR />When you create a LUN on the AutoRAID 12H, ALL the disks are used and striped accordingly.
