Installation Instructions - The Adaptec SATA and SCSI RAID Controllers Installation and User's Guide contains complete installation information for the controllers and drivers, as well as complete instructions for all utilities and Adaptec Storage Manager software. -------------------------------------------------------------------- 3. General Cautions and Notes 3.1 General Cautions - While an array is being built or cleared, DO NOT remove and reinsert any drive from that array. Doing so may cause unpredictable results for any of the controller's arrays. - While a drive is being cleared, DO NOT try to include it in a new array. Doing so may cause unpredictable results. - DO NOT move drives containing an array or volume from one controller to another while the power is on. Doing so could cause the loss of the array configuration or data, or both. Instead, power off both affected controllers, move the drives, and then restart. 3.2 General Notes - When displaying information on a physical device, the device, vendor and model information may be displayed incorrectly. - During array migration from a RAID 1 or RAID 5 to a RAID 0, if the original array had a spare drive attached, the resulting RAID 0 retains the spare drive. - After building or verifying a leg of a second-level array, the status of the second-level array is displayed as a "Quick Initialized" array. - The Adaptec controller supports only new drives or drives that have been initialized or low-level formatted. Attaching used drives could cause problems, including: ø Existing/rebuilding arrays may go off line ø Interrupted rebuilds may continue on the wrong drive - On motherboard BIOSes supporting BBS, BBS support is usually enabled on the Adaptec controller. This can cause problems during restart. WORKAROUND: Disable BBS. - After using a hot spare to successfully rebuild a redundant array, information about the hot spare drive may not display as expected. Adaptec Storage Manager may continue to display it as a global hot spare. CLI may continue to display it as a global spare, but the array will not have a spare attached. ARC (the BIOS utility) displays the spare attached to the array as expected. -------------------------------------------------------------------- 4. Array Level-Specific Notes 4.1 RAID 10 Notes - If a RAID-10 is degraded, the BIOS reports a degraded RAID-0 and a degraded RAID-1 instead of degraded RAID-10. - You cannot change the priority of a RAID-10 verify. Setting the priority at the start of a verify has no effect. The priority is still shown as high. Changing the priority of a running verify on a raid-10 changes the displayed priority until a rescan is done, then the priority shows as high again. - A RAID 10 created using the ACU using the CLEAR method shows as "UNPROTECTED" until the CLEAR operation is complete. Also, the drives' statuses are reported as Not Busy, even though the drives are clearing. - Performing a Verify and Verify/Fix on an RAID 10 displays the same message text in the event log, "Build/Verify started on second level array of array 'Array_0.'" You may see the message three times for a Verify, but only once for a Verify/Fix. - During a migration from a RAID 0 to any redundant array like RAID 1, 5, or 10, Storage Manager shows the status as "Degraded Reconfiguring" for a moment, then the status changes to "Reconfiguring." The "Degraded" status does not appear in the event log. - Adaptec 2020ZCR/2120S/2200S only -- RAID 10 arrays with greater than 20 drives support the Build/Verify command, but not the Clear command. 4.2 RAID 50 Notes - Adaptec 2020ZCR/2120S/2200S only -- RAID 50 arrays with greater than 18 drives support the Build/Verify command, but not the Clear command. -------------------------------------------------------------------- 5. Controller-Specific Compatibility Issues 5.1 SATA Controllers - These SATA RAID controllers support the importation of legacy arrays or volumes created using earlier Adaptec SATA RAID controllers. - A Clear operation on an array causes a severe performance impact to other processes, such as Build/Verify processes, involving the same array members. Therefore, Adaptec recommends that you NOT attempt any other operations while performing a Clear operation on a SATA array. - SATA events are displayed with SCSI nomenclature. - Adaptec 2810SA/21610SA only -- ACU is not supported on these controllers when installed in the following motherboards: ø SuperMicro P40C6+/P4DCE Server Board, 512 MB DDR RAM ø Intel Xeon x 2 System BIOS rev: 1.26 WORKAROUND: Use Adaptec Storage Manager on the bootable CD to create arrays. 5.2 SCSI Controllers - In Linux, the controller does not support attached CD drives during OS installation. - Adaptec 2020ZCR/2120S/2200S only -- RAID 10 arrays with greater than 20 drives and RAID 50 arrays with greater than 18 drives support the Build/Verify command, but not the Clear command. - Adaptec 2120S only -- When you flash this controller, the confirmation message says "Writing 2200S firmware (4MB) to the Controller..." The model number and size are incorrect. (The message should say "Writing 2120S firmware (2MB) to the Controller...") However, the flash process is successful. -------------------------------------------------------------------- 6. Adaptec Bootable CD Usability Issue - If you experience problems with your video display or mouse when you boot from the Adaptec CD, specify your hardware by typing the following at the command prompt: bootcd [options] or lowres [options] lowres -Forces the Adaptec CD to use a generic framebuffer of 640x480. fbdev -Forces the Adaptec CD to use a generic framebuffer of 800x600. options: ø m= ø s=
