Removal and Replacement Disk Enclosure Modules This section describes the procedures for replacing the hot swappable modules in the disk enclosure. Disk Module or Filler Module " Hot Swappable Component! This procedure describes how to add or replace disk modules and disk slot filler modules. When adding or replacing disk filler modules use the same procedure, ignoring any steps or information that applies to disk modules only. CAUTION - To prevent damage from static electricity, follow standard ESD procedures and avoid touching exposed circuitry. - Do not remove a disk module or filler module until you have a replacement. An empty slot will disrupt the cooling airflow within the enclosure and may cause overheating. - To avoid removing the wrong disk, it is recommended that you identify the disk by flashing its amber Fault LED. Identifying a disk can be done using the management software tools. Removing the wrong disk can cause data to become unavailable if the disk is part of the same volume group as the failed disk. - Never move disks from one array to another or within an array with power on. Moving disks with power on may result in data loss. Always power down the disk array before moving disks. Moving disk should not be confused with replacing a failed disk, which can be done with power on. Disk Enclosure Modules 291
