Aliasing SL3000 CAP IDs

The SL3000 has 12 CAPs, but some backup applications currently only support a maximum of 3 CAPs per LSM. CAP aliasing lets you alias CAPs 3-10 as CAPs 1 or 2.

Cap 0 is reserved for the Access Expansion Module (AEM) bulk load CAP. Since CAP 0 in an SL3000 has special attributes, it cannot be an alias CAP ID.

Map the Library CAP IDs to alias CAP IDs by using the following template.

$ACS_HOME/data/external/SL3000/SL3000_CAP_Aliases.SAMPLE

Note:

When setting CAP IDs, for Library CAP IDS:

For Library CAP IDs:

LSM must be zero (0)
ID must be 3-10
There can be no duplicate library CAP IDs

For Alias CAP IDs:

CAP number must be 1 or 2
There can be no duplicate alias CAP ID

# SL3000 CAP Aliases (SL3000_CAP_Aliases) 
# 
# This file maps real library SL3000 CAP IDs to CAP ID aliases.
# It is used when ACSAPI clients do not support SL3000
# CAP numbers greater than 2.
# (The SL3000 can have 12 CAPs, with a maximum CAP number of 11.)
# Alias a SL3000 CAP to an alias CAP number by providing the full
# SL3000 CAP ID and the aliased CAP number on the same line.
# For example:
#  SL3000 CAP ID     Alias CAP Number
#          0,0,6                    1
#
#    The LSM must be zero.
#    The CAP ID must be between 3 and 10
#    No duplicate SL3000 CAP IDs.
# Rules for SL3000 CAP IDs:
# Rules for Alias CAP numbers:
#    The CAP number must be 1 or 2.
#    No duplicate alias CAP numbers.
# # Using the CAP Aliases file:
#   (1) A # in the first column comments out a line.
#       The above CAP alias example is commented out.
#   (2) Only specify CAP numbers as an alias when there
#       is no actual CAP at that location.  For example,
#       use CAP 2 as an alias when there is no CAP 2
#       installed in the SL3000 library.
#   (3) Only CAP numbers 1 and 2 can be used as aliases.
#       NOTE: CAP number 0 (zero) is reserved for the
#       Access Expansion Module (AEM) and thus cannot
#       be specified as an alias.
#   (4) After updating the CAP Aliases file, you must:
#       a) Shutdown ACSLS.
#       b) Reconfigure ACSLS (using acsss_config) to update
#          the CAPs defined in the ACSLS database.
#       c) Restart ACSLS.
# Save the CAP alias file as:
#   $ACS_HOME/data/external/SL3000/SL3000_CAP_Aliases
# by copying and modifying the template:
#   $ACS_HOME/data/external/SL3000/SL3000_CAP_Aliases.SAMPLE
#
#   SL3000 CAP ID    Alias CAP Number
           0,0,6                   1
           0,0,4                   2
# Alias a SL3000 CAP to an alias CAP number by providing the full
# SL3000 CAP ID and the aliased CAP number on the same line.
# For example:
#  SL3000 CAP ID     Alias CAP Number
#          0,0,6                    1
#
# Rules for SL3000 CAP IDs:
#    The LSM must be zero.
#    The CAP ID must be between 3 and 10
#    No duplicate SL3000 CAP IDs.
# Alias a SL3000 CAP to an alias CAP number by providing the full
# SL3000 CAP ID and the aliased CAP number on the same line.
# For example:
#  SL3000 CAP ID     Alias CAP Number
#          0,0,6                    1
#
# Rules for SL3000 CAP IDs:
#    The LSM must be zero.
#    The CAP ID must be between 3 and 10
#    No duplicate SL3000 CAP IDs.

The example above shows a modified SL3000_CAP_Aliases file. The comment (#) character has been removed from the lines shown in bold to specify that alias CAP number assignments are enabled. In this example, the:

physical CAP ID 0,0,4 is aliased to CAP number 1.
physical CAP ID 0,0,6 is aliased CAP number 2.
