This section explains how to replace a faulty disk. The system does not 
need to be powered off or rebooted to perform this procedure.

A disk problem is usually indicated in the

 /var/adm/messages file. The 

following lines, for example, indicate a disk problem: 

Those lines, however, do not tell us which disk has the problem. One way 
of finding out is to enter an

 ls -l /dev/dsk/c* 

command and 

search the output for a device description matching that in the warning 
message. For example:

That the ”/iommu@0....” information matches the same information in the 
warning message indicates that disk c0t2d0 is the faulty disk.
