hi,<br />
which is the ServeRAID card (at bios enter in ctrl-?)<br />
The latest ServeRAID CD are 8,9 and are for SAS <br />
Last SCSI is 7 but for some cards (I need model) 6.xx is more indicated.<br />
<br />
bye<br />

I inherited an IBM xSeries 350 server with Linux already installed and RAID 5 configured across three disks.  I wanted to change to RAID 1 and have a hot-swappable disk, so I downloaded the latest ServeRAID CD and booted into it to reconfigure the array.  Only, the ServeRAID said all three disks were "defunct" and therefore we couldnt make any changes.  So I deleted the array altogether but then a scan for 'new' disks to add to a new array result in "no disks found."  Strangely, if you reboot and remove the ServeRAID CD, the server boots back into Linux.  A system/BIOS-level scan of the disks says there arent any hardware issues.  So what am I missing?  How do I get the ServeRAID to see the disks to create a new array?

&quot;defunct&quot; disks but OS boots???

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.

Server Hardware

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.
