Insert disks, wait for balancing to complete, and then create new LUNs in order for all LUN allocated space to be more than 50% of all available space (see 'armdsp -a' output). If you'll not do it, then after expanding VA may proceed with read-modify-write RAID5DP procedure instead of log-like writes and perfomance may be impacted<BR />Eugeny Fri, 28 Mar 2003 20:45:08 GMT Eugeny Brychkov 2003-03-28T20:45:08Z https://community.hpe.com/t5/disk-enclosures/va7100-information/m-p/2937864#M7975 Hello,<BR />I have VA7100 with 4 disks (36 Gb 15 Rpm), can I insert another 4 disk but with 73 Gb of capacity and 15 Rpm?<BR /><BR />Thanks For your help<BR /><BR />Filo Fri, 28 Mar 2003 08:34:16 GMT https://community.hpe.com/t5/disk-enclosures/va7100-information/m-p/2937864#M7975 Filosofo 2003-03-28T08:34:16Z https://community.hpe.com/t5/disk-enclosures/va7100-information/m-p/2937865#M7976 Hi Filo,<BR /><BR />You can mix disk capacity into an VA array.<BR /><BR />Regards,<BR />Jerome Fri, 28 Mar 2003 09:52:11 GMT https://community.hpe.com/t5/disk-enclosures/va7100-information/m-p/2937865#M7976 Jerome Baron 2003-03-28T09:52:11Z https://community.hpe.com/t5/disk-enclosures/va7100-information/m-p/2937866#M7977 You can sure put these disks<BR /><BR />More info here..<BR /><A href="http://www.hp.com/products1/storage/products/disk_arrays/midrange/va7100/index.html" target="_blank">http://www.hp.com/products1/storage/products/disk_arrays/midrange/va7100/index.html</A><BR /><BR />-USA..
