To assure the safety of the data contained on your RAID array, please run a complete backup and verify prior to beginning the following procedure. When changing any configuration or adapter card there is always a danger of data loss.
There are two possible types of failures that can occur using SCSI technology: Hardware failures and Logical failures.
When a Hardware failure occurs, something has physically affected the drive in question which prevents the drive from responding correctly, if at all. These types of failures can be catastrophic to the point where the drive fails to spin up or respond in any way, to less severe problems such as noise, head crashes, SMART errors, inability to relocate data from Bad Blocks, etc.
In these cases, when the drive is tested with the manufacturer’s testing utilities, the drive does not pass all or some of the tests. In these situations the hardware (i.e., the drive in question) must be replaced with new hardware before the array can be rebuilt. Any data on the drive may be lost, unless the drive is sent to a Data Recovery Service. In most cases, actual hardware failures are easily spotted (drives fail to spin up, make loud abnormal sounds, is not seen at all even though it is powered up and connected correctly, overheats, etc).
The second type of failure is a Logical failure. With these types of failures a device is failed from an array because of timeouts, accidental disconnection, cabling, termination, power or other problems that indirectly affects the drive resulting in a temporary condition that causes the card to fail the device. In these situatons, when the drive is tested with the manufacturer’s testing utilities, the drive passes all the tests and the drive can be used to rebuild the array. Data is still present on the drive, and depending on the type of RAID being used, the data on that drive may be recoverable by the user (as in the case of RAID 1).
Repeated drive failures can have many causes. Some of these include bad or incorrect cabling, firmware revisions on the drives, problems with an enclosure, inability to read another member of the array (as in the case of a rebuild), power problems, accidental disconnection, loose cabling, etc.
Troubleshooting of these types of failures requires that the end user try all tools available to narrow down the possible causes of the failure. The best approach is to start with the physical devices themselves and verify that all of the physical components are working, have the latest BIOS/Firmware and are properly connected.
The following list provides some of the most common items that should be checked:
1. Check the Motherboard’s BIOS revision and make sure that it is up to the latest version available from the manufacturer.
2. Check the revision of the card and make sure that the card is up to the latest BIOS/Firmware revision available on the Adaptec web site.
3. Check the firmware revision of the drives and contact the drive manufacturer to make sure that the firmware level on the drives is up to date. If the revision of the drive is not up to date, it will be necessary to flash the drives to the latest firmware available from the manufacturer. SCSI drives cannot be flashed while connected to a RAID controller. It will be necessary to use a standard SCSI card to test and flash the drives.
4. Review cabling and termination. 68-pin devices should connect to a terminated cable rated for the specific capabilities of the drives and controller (e.g., Ultra160 or Ultra320). The drives should connect starting on the connector closest to the terminator and moving towards the card without skipping connectors between the drives and the end of the cable connected to the card. Skipping a connector in between devices or at the end of the cable can cause a condition called 'Reflection', which can cancel the signal in the cable and make the card loose connection to a device, causing the card to fail the device. 80-pin devices should connect directly to a backplane rated for the specific application. The backplane should connect to the card using a 'Point to Point' unterminated cable rated for the maximum speed of the SCSI bus. Cabling/termination problems account for a large number of incidents where drives are marked failed. If the cable has been in use for some time, changing the cable may resolve issues related to bad connectors or terminators. For Ultra 320 devices Adaptec recommends using the Ultra 320 rated cables with the round-shaped bundle.
5. Adaptec does not recommend using any type of converter or trays where a converter is used to make a 68-pin drive hot-swap or to connect an 80-pin drive to a 68 pin SCSI cable. These types of converters are known to create problems with the signaling of the drives and are not supported by the drive manufacturers or by Adaptec.
6. Failed drives should be removed and tested on a regular SCSI card with the manufacturer’s testing utility to determine if the drive is fit for reuse in the system. If the drive passes all the tests, then it is safe to reintroduce the drive into the array and use it as a hot spare or recondition it to rebuild the array. Repeated drive failure during an array rebuild can also be caused by one of the remaining members of the array. If rebuilds fail, test not only the drive used for rebuilding, but also the remaining members of the array.
7. Review the resources allocated to the card by the operating system or by the motherboard. We recommend that Adaptec cards are allocated IRQ 10, 11 or higher, not shared with any other devices, for the best performance.
8. Check the driver that is installed for the card and make sure that it is the latest version available for the specific Operating System implementation.
