4.24 Mapping Drives to Home Directories 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 will reference 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 (Disk Array Mapping Information) area.
This script modifies the new volume reference object and updates the Host Server
attribute to point to the virtual NCP server in the secondary cluster.
NOTE:
Using LDIF/ICE prevents you from using the NSMI script to control the SAN. If
you want to use LDIF/ICE and the NSMI script, you must have two NCF files: one for the
SAN, and one for LDIF/ICE. The NSMI script must then call each NCF file separately.
A sample NSMI script is included below.
#!ICE -b -D LDAP -d cn=root,ou=servers,o=lab -w novell -S LDIF -f
#@ -s0 -w20
version: 1
dn: cn=HOMES_REF, ou=servers,o=lab
changetype: modify
replace: hostServer
hostServer:
cn=BCC_CLUSTER_HOMES_SERVER,ou=From_BCCP,ou=servers,o=lab
The first line in the sample script instructs NSMI to run the ICE utility.
The -b parameter automatically closes the ICE window.
The -d parameter is the administrator DN that is used to modify eDirectory.
The -w parameter is the password.
There must be a trailing space after the -f parameter.
