Removing an ASL Package
Before removing an ASL package, first find out if the package (ASL_name) is installed; enter:
# swlist ASL_name
1. To remove an ASL package, enter:
# swremove ASL_name
2. If vxconfigd is active, invoke Device Discovery Layer (DDL) through the vxdctl
command to allow the arrays to be reclaimed:
# vxdctl enable
Otherwise DDL is started automatically the next time vxconfigd is activated.
3. Verify that disk array was claimed as “Disk”.
# vxdmpadm listenclosure all
NOTE If the disk array has multiple paths, they must all be claimed as “Disk” (use
the vxddladmaddjbod command); otherwise, duplicate disk ID errors will
be detected.
Upgrading an ASL Package
Before upgrading an ASL package (installing a new version of an already installed package),
first find out if the old package (ASL_name) is already present; enter:
# swlist ASL_name
• Remove the package (ASL_name):
# swremove ASL_name
• Proceed to add the new ASL package as described by “Adding an ASL package” on
page 18“.
