I have never done this before. Do you have any step by step > procedure on how to do this? Thanks ../Murli So you wish to install the OS on the normal IDE or SCSI (or SATA) drives in the machine and reserve the SAN for database? Ok, that's fine. As far as the SAN is concerned, I always try to configure things with a hot spare if at all possible. If you need the space, then a 4-drive RAID5 is fine. If you can add a hot spare later, then that's even better. Each LUN on the SAN will appear as a SCSI disk (/dev/sda, /dev/sdb, depending on what other stuff you have). Configure your database to use raw devices or set up partitions on those disks as you see fit. Note, however, that multi-LUN setups will have problems as the default kernels from Red Hat only look at the first LUN. Just why they do that is beyond me for an "enterprise" kernel (probing multiple LUNs is pretty innocuous), but that's what they do. To get around that, you need to rebuild the kernel with "CONFIG_SCSI_MULTI_LUN=y" set and boot that kernel. If you can give us details on the system configuration (the number and sizes of IDE, SCSI or SATA drives, SAN host adapter, SAN itself, etc.), we will be able to advise you more completely. Remember, these are just _suggestions_...we aren't Red Hat employees here. ---------------------------------------------------------------------- - Rick Stevens, Senior Systems Engineer rstevens@vitalstream.com - - VitalStream, Inc. http://www.vitalstream.com - - - - If you can't beat your computer at chess...try kickboxing! - ---------------------------------------------------------------------- _______________________________________________ Redhat-install-list mailing list Redhat-install-list@redhat.com https://www.redhat.com/mailman/listinfo/redhat-install-list To Unsubscribe Go To ABOVE URL or send a message to: redhat-install-list-request@redhat.com Subject: unsubscribe </tt>
