File systems to export - only the active cluster node has exported file systems
Procedure to set up Ignite under Serviceguard
1. Create an LVM volume group to manage the shared file systems
This volume group will contain /etc/opt/ignite, /opt/ignite/boot, and
/var/opt/ignite. This must be on a RAID array and must be accessible by each of the
other cluster nodes. You must have approximately 1 GB of free disk space available in
/opt/ignite/boot. For this example, we have a 104 GB disk.
If you use a location other than /var/opt/ignite to store archives on the Ignite server,
you will need to change these instructions so your custom location is available via NFS as
part of this package. If your archives are stored outside the cluster, using a highly
available Ignite package in a Serviceguard cluster does not improve the availability of
your archives - if the archive server is down, you will not be able to perform any
recoveries.
Execute the following on the first cluster node.
# diskinfo /dev/rdsk/c13t0d2
SCSI describe of /dev/rdsk/c13t0d2:
vendor: COMPAQ
product id: HSV111 (C)COMPAQ
type: direct access
size: 104857600 Kbytes
bytes per sector: 512
#
# mkdir /dev/vg01
# chmod 755 /dev/vg01
# mknod /dev/vg01/group c 64 0x010000
For the mknod command, the major number is always 64 and the hexadecimal minor
number has the form 0xhh0000 where hh must be unique to the volume group you are
creating. You must use the same minor number for the volume group on all the nodes. You
need to determine in advance what minor number is available on all cluster members for
this new volume group by reviewing what has been used on all cluster members. Once you
determine what minor number is available, use it instead of the 0x010000 value used in
the example.
# chmod 640 /dev/vg01/group
# pvcreate -f /dev/rdsk/c13t0d2
Physical volume "/dev/rdsk/c13t0d2" has been successfully
created.
# vgcreate -s 16 /dev/vg01 /dev/dsk/c13t0d2
Increased the number of physical extents per physical
volume to 6399.
Volume group "/dev/vg01" has been successfully created.
Volume Group configuration for /dev/vg01 has been saved in
/etc/lvmconf/vg01.conf
