RH Switching rootvg/sanvg to New SAN cont'd
Hi, wow that sounds awesome - thanks for the insights.
This is a live production server I have to work with - any chance you know how to accept the new LUN presentations on RH - and how to write the pvmigrate command?
The entire rootvg including /boot is on the SAN - so do you think the pvmigrate will cover the /boot as well - or will I have to create a new /boot on the new SAN?

Hi everyone,
I wonder if I can canvas any opinions or thoughts (good or bad) on SAN attaching a SUN V880/490 to an EMC Clarion SAN?
At the moment the 880 is using 12 internal FC-AL disks as a db server and seems to be doing a pretty good job. It is not I/O, CPU or Memory constrained and the... (2 Replies)

I want to increase the size of /tmp by 1GB
I know that the command is
chfs -a size=+1G /tmp
But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks.
Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ?
Please advise. (1 Reply)

LEARN ABOUT FREEBSD
boot.config
BOOT.CONFIG(5) BSD File Formats Manual BOOT.CONFIG(5)
NAME
boot.config -- Configuration file for the boot blocks
DESCRIPTION
The boot.config file contains options for the FreeBSD boot block code.
When the FreeBSD boot loader runs, it searches the ``a'' slice of the boot partition for a boot.config file (as a result, slices which are
missing an ``a'' partition require user intervention during the boot process). If the boot.config file is found, its contents are used as
the default configuration options for the boot block code and are echoed to the system console.
A valid format of this file is to put BIOS drive number, a controller type, a unit number, a partition, a kernel file name, and any other
valid boot(8) option on a single line, as it is done at the ``boot:'' prompt.
The options related to the boot image selection described below and all the other options available for boot.config are documented in detail
in the boot(8) manual page.
FILES
/boot.config parameters for the boot blocks (optional)
EXAMPLES
The command:
# echo "-P" > /boot.config
will activate the serial console of FreeBSD.
The command:
# echo "1:ad(1,a)/boot/loader" > /boot.config
will instruct the second stage of boot(8) on the first disk to boot with the third boot(8) stage from the second disk.
The command:
# echo "1:ad(1,a)/boot/loader -P" > /boot.config
will do both of the above.
