If you follow the HP manual and don't do anything wrong, or nothing happens like a powerfailure etc, then the data will be intact. The problem is that it is always possible for something to go wrong, so having a verified good backup is essential before expanding the array.

I have a HP Proliant ML350 that currently has 3 72.8 GB drives in a RAID 5 array. &nbsp;I would like to add three more to max out the available hot swap bays. &nbsp;My question is, if I chose to &quot;Expand&quot; the array to include the additional 3 disks, will this wipe out my data or will my data still be intact? &nbsp;I called HP support but they would give me a definate answer, I guess for legal reasons, but surely someone can tell me whether an array expansion will or will not destroy your data. &nbsp;I've done this on DELL PoweEdges before and then used the Windows '03 partition tool to increase the logical disk size on the data partition. &nbsp;Should I have the same result on this Proliant ML350?

I have a HP Proliant ML350 that currently has 3 72.8 GB drives in a RAID 5 array.  I would like to add three more to max out the available hot swap bays.  My question is, if I chose to "Expand" the array to include the additional 3 disks, will this wipe out my data or will my data still be intact?  I called HP support but they would give me a definate answer, I guess for legal reasons, but surely someone can tell me whether an array expansion will or will not destroy your data.  I've done this on DELL PoweEdges before and then used the Windows '03 partition tool to increase the logical disk size on the data partition.  Should I have the same result on this Proliant ML350?

System Utilities are a type of system software used to support the computer infrastructure, distinguishing it from application software which is aimed at directly performing tasks that benefit ordinary users. Commonly used utilities include password managers, disk managers, system monitors, data synchronization tools, security and antivirus software and editors.

System Utilities

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
