Troubleshooting Business Continuity Clustering 1.1
75
The cluster node that hosts the Identity Manager driver should have a read/write replica with
the following containers in the replica (filtered replicas were not supported in Business
Continuity Clustering 1.0):
Driver set container
Cluster container
(Parent) container where the servers reside
Landing zone container
Ensure that you have full read/write replicas of the entire tree at each data center.
4.23 Mapping Drives in Login Scripts
Consider the following when mapping drives in login scripts in a BCC:
Using an FDN (such as map s:=BCCP_Cluster_HOMES.servers.:shared) to a cluster-enabled
volume has been tested and does not work.
When the resource fails over to the secondary cluster, the DN does not resolve to a server/
volume that is online. This causes the
map
command to fail.
Using the
SLP Server Name
/VOL:shared
syntax has been tested and works.
SLP Server Name
is the name being advertised in SLP as specified in the resource load script.
This method requires a client reboot.
See
TID 10057730 (http://support.novell.com/docs/Tids/Solutions/10057730.html)
for
information on modifying the server cache Time To Live (TTL) value on the Novell Client
TM
.
4.24 Mapping Drives to Home Directories by
Using the %HOME_DIRECTORY Variable
Consider the following when mapping drives in login scripts in a BCC.
Using the
%HOME_DIRECTORY
variable (such as map u:=%HOME_DIRECTORY) has
been tested and does not work.
When you fail the resource over to the secondary cluster, the %HOME_DIRECTORY variable
still resolves to the old volume object, and the
map
command fails.
Using a temporary environment variable has been tested and does not work.
For example:
set FOO=%HOME_DIRECTORY
MAP u:=%FOO
Using a false volume object along with ICE and LDIF has been tested and works.
Create a new volume object that references the real volume object.
The Host Server attribute must point to the virtual NCP server in the primary cluster, and
the Host Resource Name attribute must specify the name of the volume. This new volume
object can be referred to as a volume reference.
All User objects must be modified to have their Home Directory attribute reference the
new volume object (volume reference).
Use LDIF and ICE in the NSMI script (SAN Array Mapping Information) area.
