Disk Module Replacement Procedures
CAUTION! Not all disk modules are hot pluggable. See Table 11 and the appropriate
replacement procedure in this chapter for information on replacing a disk module.
NOTE! Replacement of a disk module is not the same as installing additional capacity to an
operating storage system. To add capacity, see "Installing Additional Disk Modules".
