This is a complex question. I will try to provide an answer that is not as complex. The # of arrays supported on a single RAID adapter depends on the controller used. for instance the IBM ServeRAID adapter supports 8 arrays under some conditions and less under others. The # of drives per...

The serveRAID utility should allow you to setup your array and define your logical drives. For it to work properly your physical hard drives must appear a RDY in the configuration tree under Physical devices for the channel they are attached to. By the Way, The ServeRAID manager will only...

You might try setting the IRQs manually and not allowing PCI to allocate the IRQs. PNP in my experience tends to be a dream especally with high performance devices like the ServeRAID adapters. Every cold boot, PCI allocates resources and it is possible to end up with a resource conflict. I...

This may depend on the type of RAID controller you use. The big performace advantage of RAID is through the use of multiple read/wright heads working independantly, one set with each drive. As such the more drives you have in an array the better the performance. Therotically of course. You...

This usually indicates a problem with the signal cable, SCSI bus termination, one of the devices/drives or power to the drive(s). One other important point. This adapter will not support 8 bit SCSI devices by design. First disconnect the signal cable and press CtL+I during ServeRAID...

A few things to look at. First you will need the OS/2 7800 fam drivers for the 2940 adapters. Second, I suggest you change 3 settings for the tape drive. in the SCSI Select go into Adapter configuration/device configuration. then change the following for the SCSI ID of the tape drive. 1...

neilcresswell is correct, each processor requires a voltage reg. module. Also the processors must be the same speed and cache size. The gold print on the top edge of the processor will give you the speed and cache size.

Which ServeRAID adapter do you have and wqhat level of BIOS are you trying to update it with. The current BIOS for the ServeRAID family of adapters is 5.11 available from IBM. ServeRAID adapters started with the I, II, 3L, 3H, 3HB, 4L, 4M, 4H and a 5i. Any adapter prior to the 4x will have to...

Well several things come to mind. First, clocks built into computer system boards have always been just a convinence device for the user, accuracy was never a design point. If accuracy is a requirement your best bet, and most economical, is the free software provided by the National Institute...

Have you tried callinf 1-800-IBM-SERV? You will be prompted to enter the 4 digit model type (8476) in the phone switch. Some one there will be happy to assist you, Based on my experiences. Good luck.

A standard PCI adapter should fit. The adapter slots meet the established PCI design standards.

It is possible to down flash the card by entering Ctrl+F at the BIOS flash menu. If your adapter has the battery module I would not flash it beyond 4.84 for now. Now for the problem. 1st In order to flash to 4.x or later, the current flash level on the adapter must be at 3.x or later. If your...

Hi, are the drives the same size? If you are increasing your array size you may have other options that can save you time, e.g. Drive Migration, which is supported on the IBM ServeRAID adapter at flash level 4.3 or later. If you wish to replace the drives and recreate the array and logical...

Hi, from your info, it looks as if you have set a 2047MB Swapp partition. If I'm not mistaken, you should keep the swapp partition to less than 128MB. Try setting the swap partition to less than 128MB and give that a try. Good luck

Scooterscott, Take a look at some of the online auction sites like ebay. Look for an IBM ServeRAID adapter, I have seen them for less than $50. It will do what you need PLUS. With the latest microcode you will even be able to add a drive after your array has been created and in use. The...

The LED on the RAID controller may not be anything other than the controller is online. I agree your drive arrangement appears to be unusual. It appears you have 3 HDs with 1 HD in a RAIL level 0 with 3 partitions. What type of RAID adapter are you using? What RAID level do you have...

I suspect your problem is not the platter but more basic than that. If a liquid containing conductive material, like sugar or other agents are spilled on a drive, it will form new paths for the voltage, current and of course the controlling signals of the device. The problem will be worse if...
