HP Insight Cluster Management Utility manual Operating system support, Rhel 6 support

2.2.3 Operating system support

HP Insight CMU software is generally supported on Red Hat Enterprise Linux (RHEL) 5 and 6; and SUSE Linux Enterprise Server (SLES) 10 and 11.

The HP Insight CMU diskless environment is supported on RHEL5, RHEL6, SLES10, and SLES11.

Ubuntu is supported on the compute nodes only, on HP Ubuntu certified servers. Contact HP for support.

Debian is supported on the compute nodes only, but requires active approval and verification from HP. Contact HP for support.

CentOS and Scientific Linux are supported on the compute nodes and the management nodes, but require active approval and verification from HP. Contact HP for support.

For details on specific operating systems supported, see the HP Insight CMU release notes for your version of the product.

2.2.3.1 RHEL 6 support

HP Insight CMU v7.1 supports RHEL6 on the management node and compute nodes. HP Insight CMU continues to support a mix of operating systems. For example, RHEL6 is not required on the management node if RHEL6 is installed on your compute nodes. However, you must use HP Insight CMU v7.1 when RHEL6 is installed anywhere in your HP Insight CMU cluster. As with all HP Insight CMU releases, all backup images from previous HP Insight CMU versions can be used with v7.1.

HP Smart Array warning with RHEL6 and future Linux releases

If your compute nodes have P212, P410, P410i, P411, P711, P712, P812, or all newer controllers proposed by HP after April 1, 2011, then running RHEL6+ (or SLES 11SP1 with the optional driver) will make them appear as standard /dev/sd* SCSI devices and not as /dev/cciss/c*d*. Other controllers such as HP Smart Array P400, P800, and P700m will continue to appear as /dev/cciss/c*d* with RHEL6+.

Having these particular nodes means that HP Insight CMU users might have to create new logical groups and declare backup devices as /dev/sd* instead of /dev/cciss/c*d*. For example, you can clone a RHEL5 image on a P410i-based compute node, then clone it with RHEL6 and HP Insight CMU will switch from /dev/cciss/c*d* to /dev/sd*.

As a result of support for RHEL6, HP Insight CMU v7.1 now supports:

•The ext4 file system

•UUID support in fstabs (replaced at backup by HP Insight CMU)

•dhcpd.conf alternate path support

•SHA512 password support for RHEL6 management nodes

•hpsa/cciss support
