Attention
When power is removed from a hot-swap drive, the drive immediately parks the heads,
locks the actuator in the “landing zone,” and begins spinning down. However, the spinning
down of the disk might require up to 20 seconds after power is removed. Do not move the
drive while it is spinning down. Moving the drive while it is spinning down might damage the
drive.
2. Wait 20 seconds to allow the physical drive to completely stop spinning.
3. If you are certain there is nothing wrong with the physical drive you removed,
gently reinstall the drive into the server. Make sure the drive is completely
installed in the backplane connector.
Otherwise, replace the physical drive with a new drive that is the same size (or
larger) and continue with the rebuild operation.
Notes:
a. If multiple drives fail in separate arrays (one physical drive per array),
replace each defunct physical drive. If multiple physical drives fail at the
same time within the
same array, contact your IBM service representative.
b. Although it is possible to rebuild a defunct physical drive to an online
physical drive that is defective, avoid doing so.
Recovering from multiple physical drive failures (Windows only)
Important:
v There is no guarantee that this procedure will recover data.
v This procedure requires a ServeRAID-3 or ServeRAID-4 controller with BIOS and
firmware at version 4.x or later installed
prior to the physical drive failures.
v Repeat this procedure for each array that contains multiple physical drives marked
defunct.
The ServeRAID controller is designed to tolerate a single physical drive failure in an
array. Although there is no guarantee that intact data can be recovered after a
multiple physical drive failure in an array, the following procedure offers the
possibility of a successful recovery in the event that multiple physical drives are
marked defunct within the same array.
You will need the following:
v An IBM ServeRAID Support CD, version 4.80 or later.
v A diskette containing the IPSSEND command-line program. This can be either
downloaded from the IBM Web site or created using the
IBM ServeRAID Support
CD.
v
A version of DUMPLOG and CLEARLOG appropriate for your operating system.
You can download both programs from the IBM Support Web site at

Notes:
1. If you have downloaded a newer version of the IBM ServeRAID Support CD, do
not upgrade the BIOS and firmware until you have completed this procedure.
2. The following procedures rely upon logging functions introduced in version 4.0
of the IBM ServeRAID Support CD. The ServeRAID controller must have had
BIOS and firmware version 4.x or later installed prior to the multiple physical
drive failure.
