Solaris and Solaris Cluster on HP ProLiant Servers


Sun Microsystems announced today, support for Solaris Cluster on non-Sun servers, through the Solaris Cluster Open Hardware Program. To learn more about supported configurations and FAQ's please visit: http://www.sun.com/software/cluster/ohp. Sun and HP customers now have the option of running Solaris Cluster on HP Proliant DL 385 G2 and Proliant DL 585 G2 servers. The benefit being a robust availability solution with unequaled reliability for end users.

The intent of this blog entry is to share some of what we learned during the initial implementation of the Solaris Cluster Open Hardware Program on HP ProLiant servers.

First step in the process of the Solaris installation, is to familiarize yourself with the documentation that ships with the HP Proliant servers. Second step is to ensure that the servers are racked and cabled (power and network) and ready for configuration of the iLO 2 processor. HP ProLiant servers utilize the Integrated Lights-Out 2 (iLO 2) remote management software. This is similar to the Advanced Lights Out Manager (ALOM) host management software that Sun x86/x64 servers use. The iLO 2 processor is accesible via a dedicated ethernet port and gets its power from the auxiliary power plane of the server, so it is always available when the server is plugged in. The iLO 2 processor can be assigned a static IP address or can be configured to obtain its IP address via DHCP (this is the default setting for servers shipped from HP). Please refer to the HP Integrated Lights-Out 2 User Guide for changing the Network Settings to utilize a static IP.

Consoles: you have the option to use the serial connection on the servers (ttya), a keyboard and monitor, or a virtual serial console from the iLO 2. Configure and set up the appropriate choice you feel best for your environment.

Hardware RAID for the internal drives is enabled by default. Thus, if using two internal drives, a RAID 1 logical volume is preseneted to the OS.

The different ways to install Solaris on HP ProLiant servers are documented in the  Sun Solaris 10 Deployment Guide for HP ProLiant Servers.
We recommend the PXE based network installation method. A couple of observations:

- The standard Solaris distribution does not contain packages for the hardware RAID driver (CPQary) and the onboard NICs (BRCMbnx). These drivers can be downloaded here.

- Once the dhcp server is set up, modify the file /tftpboot/menu.lst<BootFile: Name> as follows:

Change line 4 from

    kernel /I86PC.Solaris_10-1/multiboot kernel/unix -B

to:

    kernel /I86PC.Solaris_10-1/multiboot kernel/unix - install dhcp -B

We hope you find these tips useful. Stay tuned for further updates as the Solaris Cluster Open Hardware Program expands.

It's been awhile since my last blog, but hopefully most of you have had a chance to keep up with our posting's from month to month, as we continue to include Sun Cluster solutions on 3rd party storage arrays, “http://www.sun.com/software/cluster/osp/”.  Everyone has been active, and we are all excited to be able to offer Sun Cluster 3.2 solutions in various configurations on new and established server platforms. As of today, there are many offerings in relation to Sun Cluster 3.2 support that are detailed below, which we are excited and proud to offer.


   IBM (Sparc & x64)

   HP (Sparc & x64)

   NetApp (NAS – Sparc & x64)

   LSI (Sparc & x64)

   HDS (Tagmastore on Sparc & Lightning 9xxx on Sparc & x64)

   Fujitsu (Sparc)

   NEC (Sparc)

If you haven't checked the matrix recently, please do so. I'll be back next month with more postings and news in relation to the Sun Cluster Open Storage Program. Until then, tell a friend!
