Note - The descriptions regarding the cfgadm command in the service manual of the server used are not applicable to the disk drives that make up a RAID volume. You do not need to cancel the RAID configuration before a replacement with a new disk drive or a hot swap. Displaying the status with the LSI SAS2IRCU utility You can also use the LSI SAS2IRCU utility to check for a disk drive failure. For details of the SAS2IRCU utility, see the beginning of " 14.2 Configuring Hardware RAID ." 14.2.10 Replacing a failed disk drive This section describes how to replace a failed disk drive among the disk drives that make up a RAID volume. RAID0 If a disk drive in a RAID0 volume fails, all the data in the volume is lost. Replace the failed disk drive with a new disk drive of the same capacity, re-create the RAID0 volume, and restore the data from a backup. RAID1 Replace the failed disk drive with a new disk drive of the same capacity. Synchronization begins when the new disk drive is incorporated into the RAID volume. In a hot spare configuration, the hot spare disk drive is automatically reconfigured to restore data. Once the failed disk drive is replaced with the new disk drive, the new disk drive is set for the hot spare. RAID1E Replace the failed disk drive with a new disk drive of the same capacity. Synchronization begins when the new disk drive is incorporated into the RAID volume. In a hot spare configuration, the hot spare disk drive is automatically reconfigured to restore data. Once the failed disk drive is replaced with the new disk drive, the new disk drive is set for the hot spare. Hot spare Data is automatically restored to the RAID volume. Replace the failed disk drive with a new disk drive of the same capacity, and configure the hot spare. 14.2.11 Re-enabling a hardware RAID volume This section describes how to re-enable a hardware RAID volume after replacing the CPU memory unit (lower) of the SPARC M10-4/M10-4S or the SPARC M10-1 motherboard unit. This is necessary when the hardware RAID volume is configured as a boot device. Chapter 14 Configuring a Highly Reliable System 337
