+
+directory where <os> and <arch> are defined in the I<nodetype> table. 
+
+Second, add rpm names (without version number) into
+
+ /install/custom/install/<ostype>/profile.otherpkgs.pkglist 
+
+where <profile> is defined in the I<nodetype> table. <ostype> is the operating system name without the version number. The following os types are recognized by xCAT.
+
+  centos

+2. To re-run all the postscripts for the nodes, type

+
+3. To re-run the syslog postscripts for the nodes, type
+
+   updatenode <noderange> syslog
+

+   updatenode <noderange> script1,script2
+
+Note: script1,script2 may or may not be defined in the postscripts table. However if  you want script1 and script2 get invoked next time the nodes are deployed, add them into the postscripts table.
