Before going into detail, some information on the so-called Hot Plug of fault tolerant disk

arrays (RAID 1/4/5/10) is given below.

Fault tolerant means that a hard disk which is part of a RAID 1/4/5/10 Array Drive can fail

without causing data loss on the Array Drive. At the same time, the Array Drive remains

fully accessible. Obviously, the Array Drive then lacks the redundant data, therefore the

defective disk should be replaced by an intact one as soon as possible. In chapters C

(RAIDYNE Quick-Setup) and L (GDTSETUP in Detail), we have shown with various examples

how to exchange a defective drive with GDTSETUP. Moreover, we described the functioning

of the so-called Hot Fix drive. This "constantly available spare part when needed" auto-

matically integrates itself into the Array Drive and is therefore the quickest means of re-

gaining a redundant Array Drive.

The Hot Plug function enables the replacement of a drive of an Array Drive (either in the

ready or fail state) while the system continues to run, that is, without having to shut down

the NetWare fileserver for instance. A drive replacement may not only become necessary

when the drive has already failed, but also when there are signs that a failure could occur

soon (strong whistling of the hard disk, or constant retries of the read/write head).

Only those users with thorough knowledge of RAID and the ICP Controller should use the

Hot Plug function. Improper use can lead to data loss. (Naturally, we have integrated all

kinds of security provisions into the ICP Controller and GDTMON. But how can we prevent

a user from plugging out the wrong drive?). We recommend that you document each Array

Drive immediately after its configuration with GDTSETUP. This record should at least com-

prise the following information:



 To which ICP Controller has the Array Drive been connected ?



 Which hard disks are part of the Array Drive ?



 To which SCSI ID have they been set ?



 Which SCSI devices terminate a SCSI channel ?

In addition, the hard disks themselves should be labeled with the above information. The

following is an example of such a label.
