The statement comes from a Los Angeles-headquartered HDD, SSD, and RAID data recovery firm aptly named Secure Data Recovery that has been in business since 2007 and claims to have resolved more than 100,000 cases. Īn analysis of 2,007 damaged or defective hard disk drives (HDDs) has led a data recovery firm to conclude that 'in general, old drives seem more durable and resilient than new drives.' Further, eight of the 13 SMR drives from Western Digital and Seagate registered fewer than 15,000 power-on hours on average. The firm found that, 'Western Digital's SMR models had a 12.7 percent shorter lifespan than their CMR counterparts, Seagate's SMR models had a 19.7 percent shorter lifespan than their CMR counterparts,' when looking at average power-on hours. It said that 37 percent of the Western Digital and Seagate drives analyzed featured SMR. Scroll down to VxRail and select 'Skyline Health'ģ.Update : Secure Data Recovery provided us with a little more information on the defective HDDs tested. Click on the node in VxRail and on the right hand window, select 'Monitor'Ģ. The follow up and check on the rebalancing status:ġ. System will load the new disk and start the rebalance Select the appropriate new disks and click 'Add Disk'ĩ. The system will look for the unused disks that are installed in the node and present themĨ. Next you have the option to select if you have already added the disk or let the VxRail suggest where to add the disks (slot)ħ. Select the node (physical picture) that you would like to add the disk to and on the right hand side, select 'Actions' menu and choose 'Add Disk'Ħ. Select the Monitor tab and scroll down to the VxRail section and click on 'Appliances'ĥ. Repeat this process for each node and each disk group that you'd like to addĤ. check the disk or disks that you would like to add to the group and select 'Add'Ĩ. When you click Add Disk, it will populate with the disks that the node sees as available (not in use). Select the appropriate disk group under each node and click 'Add Disk:' from the menuħ. This view will show each node and its disk group below each nodeĦ. Scroll down to the vSAN section and select Disk Managementĥ.

Add the physical disks into the correct nodes for VxRailĤ. This process below shows two methods to add a new disk to a disk group or to multiple disk groups.
