Purpose

RAHU is the new storage server and possibly the first building block of a Fibre Channel SAN. It will be hosting home directory and other storage using Veritas filesystem and volume manager (VxFS and VxVM) on Fibre Channel RAID arrays (currently utilizing a single Apple Xserve RAID for 2 TB of storage). Access to file services is currently only over NFS.

Dependancies

RAHU is dependant on SHANTI for the NIS/YP domain, RADIUS authentication, and proper functioning of the self service quota system. DNS (PAX or EIRENE) is used for normal operation in NFS services.

Startup/Shutdown

Startup:

• Turn on the Xserve RAID system by hitting the power button at the back of the unit (above the power supply on the right side as looking at the back of the unit).
• Connect to the serial ALOM port and issue a poweron command or hit the power switch behind the bezel on the front of the unit.

Shutdown

• Issue the command shutdown -g 0 -y -i 5 to shutdown the system and turn off power.
• Press and hold the power button on the Xserve RAID until the lights stop flashing and the unit turns off.

Notes

12 Apr 2004

Upgraded last week form VxFS/VxVM 3.5 to 4.0. There was an issue with 4.0 thinking that DMP was enabled on the Xserve RAID (controllers c3 and c4) and thinking that the second LUN for the 500 GB RAID 5 sets was an alternate path to the first LUN. This caused filesystem corruption. The fix was to use vxdiskadm and choose option 17 to prevent multipathing on specific controllers.

A snapshot is generated every night, Sunday through Friday, of the /home/fc-raid-00-1 filsystem (home directories) for both NetBackup and instant recovery purposes. Currently, only administrative access is granted to the snapshot; we will begin exporting it for user access in late summer.

The Quota perl module makes and installs fine. The Makefile.PL needs to have the VERITAS support check commented out, since it relies on older Solaris/VERITAS versions and the current version works with standard quota system calls.

All the perl modules in /usr/local/source are currently installed. They are there to support: quotas, ecs-usermgr, and most of the stuff for self-service quota server tools. They are made with standard /usr/bin/perl and the Forte C compiler.

21 Apr 2004

Installed the base PostgreSQL binaries compiled locally and installed iinto /usr/local/pgsql. The version of PostgreSQL is 7.4.2 (currently the latest). This is primarily to support the quota database on SHANTI. DBD-Pg is also now installed for perl.

20 May 2004

Installed Net-SNMP which required the OpenSSL 0.9.7 package. Installed 0.9.7 over the top of 0.9.6, since the only thing using 0.9.6 was PostgreSQL and the SSLeay perl modules.
