• Media-The current status of the physical disk media for the chunklet. The value is failed if the media has encountered errors and is unavailable, or valid if it is available for use. • Sp-The spare status of the chunklet. Y indicates the chunklet is used for spare, N indicates that it is not. • Cl-The cleaning status of the chunklet. Indicates whether the chunklet is in the process of being reinitialized for use, as happens when a physical disk is added to the system, or an LD is removed. The value can be Y (cleaned), N (not cleaned), or Cg (being cleaned now). • From-The initial location of the chunklet prior to relocation. The format is PD:CH, where PD is the physical disk ID and CH is the chunklet ID. • To-The destination location of the chunklet during relocation in the format PD:C H. Logical Disks and Chunklet Initialization After deleting logical disks, the underlying chunklets must be initialized before their space is available to build logical disks. The initialization process for chunklets generally takes about one minute per 1GB chunklet and 20 seconds per 256MB chunklet. To see chunklets that are currently in the process of being initialized, issue the showpd -c command. Chunklets that are uninitialized are listed in the Uninit column. Recovering Failed RAID Sets Failed RAID sets can prevent chunklet relocation, which in turn prevents servicemag operations from completing. Use the checkld command to recover data from a failed RAID set: checkld -y -rs -recover -fd:-fp, where: • -y-Indicates that any errors that are found should be fixed; this option is required when using the -recover option. • -Specifies the name of the LD that contains the failed RAID set. • -rs -Specifies the RAID set number within the LD to be checked, fixed, and recovered. • -recover -fd:-fp-Specifies the chunklet to be recovered by physical disk and chunklet position. Viewing Hardware Inventory Use the showinventory command to display information about all the hardware components in the system. The command output is divided into sections such as the following: • Nodes • PCI Cards • CPUs • Internal Drives • Physical Memory • Power Supplies • Battery • Node Fans • Port Inventory • Cage Inventory • Disk Inventory Recovering Failed RAID Sets 109
