Subdirectory names

How subdirectories are used as names for IBM Storage Archive Library Edition.

An LTFS-formatted cartridge is accessible as a subdirectory under the root mount point of IBM Storage Archive LE. The volume serial number (VOLSER) for the cartridge is set to the subdirectory name. IBM Storage Archive LE reads the VOLSER on the bar code label through the tape library's bar code reader, and sets the VOLSER in the VOL1 record on tape, and its cartridge memory, during the format process. If a volume name is assigned when the cartridge is formatted, the subdirectory name is formatted VOLSER – volumename. For more information, see Volume serial numbers and names.

Note: The volume name can be set up to 255 characters. If the user sets a volume name near 255 characters, the total length of the VOLSER – volumename would exceed 255 characters. Due to the specification of the file system, any additional characters of the subdirectory name that exceed the 255 character limit are omitted. The length of the subdirectory name becomes 255 characters.

Possible names for a IBM Storage Archive LE subdirectory are summarized in Table 1.

Table 1. Cartridge status and subdirectory name
Cartridge Status	Subdirectory name
LTFS-formatted	VOLSER `VOLSER – volumename`
LTFS-formatted Permanent write failure.	VOLSER `VOLSER – volumename` Note: The cartridge becomes read-only when it is in the drive, but the name is not changed. A cartridge with a permanent write-failure status becomes inconsistent. The cartridge might need to be recovered by using the leadm tape recover command. For more information, see leadm.
Cartridge without a bar code Cartridge with an error on reading its bar code.	UNKN0000 Note: This unique character designation is reserved for unknown cartridges. Note: The cartridge cannot be accessed through file system requests. Also, no operation that is provided by the leadm command is allowed.
Not LTFS formatted or Inconsistent LTFS format.	VOLSER Note: This status occurs before the cartridge is accessed and the status is confirmed. N/A (not shown) Note: This status occurs after the cartridge is accessed and the status of "not LTFS formatted" or "inconsistent LTFS format" is confirmed.
Cleaning Cartridge	N/A (not shown)
