For details about the installed commands, use the rpm -qi hp.com-npartition-cmds command. * HP nPartition Provider Version 1.03.00 -- Provides the WBEM nPartition Provider modules for Linux, which are used by the nPartition Commands for Linux. For details about the installed provider, use the rpm -qi hp.com-npartition-providers command. To install the nPartition Commands and WBEM nPartition Provider, use the installer that also is provided on HP Enablement Kit for Linux Supplemental CD. You can use this release of the nPartition Commands and nPartition Provider for Linux to manage a cell-based HP server from the following operating systems: * Red Hat Enterprise Linux 3 * Red Hat Enterprise Linux 4 * SuSE Linux Enterprise Server 9 You can use the nPartition Commands from any of these Linux releases running on an nPartition. You also can use the nPartition Commands from remote HP Integrity servers running these Linux releases.

Changes and Limitations for Red Hat Enterprise Linux 4 This section describes changes and known limitations with this release of the HP nPartitions Commands and nPartition Provider for Linux. NOTE The following changes and limitation are specific to Red Hat Enterprise Linux 4. This information does not apply to Red Hat Enterprise Linux 3 or SuSE Linux Enterprise Server 9. Location of cimserver configuration files has changed. In Red Hat Enterprise Linux 4 Update 2, the cimserver configuration files such as server.pem (digital certificate file), client.pem (Shared Authentication Store file), and others now are stored in the /etc/Pegasus/ directory. These files are used in enabling remote administration; for details, see the parstatus (1) manpage Dependencies section. WBEM authorization is through PAM. In Red Hat Enterprise Linux 4 Update 2, the /etc/Pegasus/access.conf file specifies the users who are allowed to send WBEM requests to cimserver. By default, access.conf is configured to allow only the pegasus user to send remote requests to cimserver, and by default it allows only the root and pegasus users to send local requests. Only the parstatus and fruled commands are supported for remote access by default. To enable remote access of all nPartition Commands, you must allow the root user to send remote requests. SELinux must be disabled or set to permissive mode to support nPartition Commands. The Red Hat Enterprise Linux 4 release includes Security-Enhanced Linux (SELinux). For the HP nPartition Commands for Linux to work, SELinux either must be disabled or put in permissive mode. The nPartition Commands for Linux will not work when SELinux is in enforcing mode.To put SELinux in permissive mode, use the setenforce 0 command. To disable SELinux, modify the file /etc/selinux/config . For details, see setenforce (1). # # #
