Hello.   Download OpenManage Server Administrator v7.4.0.2 form this link: [URL]    Replacing 146 GB drive with 600 GB drive will not provide any additional space that you need because the array will only utilize 146 GB of 600 GB total space on the new drive. What controller do you have installed? In case that your controller does not support the Online Capacity Expansion (OCE)  the only option available for you might be to backup your data, delete the existing RAID array and re-create another array with the new 600 GB drives. Restore data from backup and re-install the operating system.  
Hello,  We have an old Dell Poweredge 2900 server running our SQL Server database.  Last week we discovered that the Raid 5 is degraded and 1 of the disks disk 0 is completely down and showing amber light.  We were already running low on disk space so even if we got it up and running by purchasing a replacement of the SAS 146GB 10k disk we would still be running out of database storage.  I have purchased a Seagate Cheetah 15k SAS 600GB ST3600057SS and would like to replace the failed drive with it.    Question: 1) Open manage is not installed but would like to install.  What version can I use for this Server 2900. 2) Can my replacement of a 146GB with a 600GB work? Please for your advise since this database server is key to my business operation.  Thanks in advance
