    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello Everyone - &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I'm relatively new vSphere, so I apologize ahead of time if this is a topic that has been covered previously. First time post to vmware communities&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I have a Dell Server running ESXi v6 with a RAID 5 datastore that is running out of space. Ideally, I'd like to be able to add the disks without rebuilding and losing my existing file system. I built the array using the on-board H700 PERC BIOS Utility. I have added additional disks to existing RAID 5 arrays on Windows boxes running Dell Open Manage in the past, but wasn't sure if there was similar functionality built into ESXi or not. I am still doing some digging into the H700 PERC BIOS itself, but haven't found where anyone has added the new disk via the BIOS utility without a rebuild of the array. Before doing any work, I will make sure that I have everything backed up, but it would be nice if I could just add the hot plug drive, reconfigure online and resize the datastore. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thank you for the benefit of your experience in this matter!&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks!&lt;/P&gt;&lt;P&gt;Bill &lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;I would highly recommend to use the current problem to rebuild your RAID and get rid of the raid 5 !&lt;BR /&gt;The chance that a future drive-failure of one the drives of a raid5 set will result in a complete loss is significantly higher than with a RAID 1 or 10.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Continuum has a very good point about RAID 5 - it is not considered a best practice these days due to the length of time it takes rebuild the array. With a larger window, you have a increased chance of losing another disk during the rebuild process, resulting in losing everything.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;That being said, you can install Dell's Server Administrator software on a ESXi host. You can find the VIB files on Dell's site (&lt;A href="http://www.dell.ca/support/contents/ca/en/cadhs1/article/Product-Support/Self-support-Knowledgebase/enterprise-resource-center/Enterprise-Tools/OMSA" title="http://www.dell.ca/support/contents/ca/en/cadhs1/article/Product-Support/Self-support-Knowledgebase/enterprise-resource-center/Enterprise-Tools/OMSA"&gt;Dell OpenManage Server Administrator | Dell CANADA&lt;/A&gt;); just install those and then you'll be able to pull up the Server Administrator via a web page.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Thanks for the comments and suggestions! To get me over my hurdle for the moment, I'm stuck adding to the existing RAID-5 array, but based on the comments from you guys, I will start looking into using a different RAID format. Unfortunately, it is something I will have to present and make the case for before I can do it. &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks for the help and links! I really appreciate it!&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
