Veritas_cluster SETUP example

Veritas Cluster Server - VCS

Versions: 1.0.1, 1.0.2, 1.1, 1.1.1, 1.1.2, 1.3.0 (The difference between 1.1.1 og 1.1.2 is just VRTSgab)

HEARTBEAT:
1) heartbeat is on layer 2, with LLT /GAB (Low Latency Transport/Group Atomic Broadcast)

Script-setup NFS Script-setup ORACLE S_delete group tuning-script v.01

Simple Setup(before 1.3.0) (I've never tried this):
cd /opt/VRTSvcs/wizards/config
./quick_start

Simple Setup(from 1.3.0) (even install the packages for you, but NOT the clusterManager(gui))
cd /cdrom/cdrom0
./VCSinstall

manuel setup:

make /etc/llttab and /etc/llthosts /etc/gabtab

#cat /etc/llttab:(before 1.3.0)
set-node VXcluster1
link qfe0 /dev/qfe:0
link qfe1 /dev/qfe:1
start

#cat /etc/llttab:(from 1.3.0)
set-node VXcluster1
set-cluster 0
link link1 /dev/qfe:0 - ether - -
link link2 /dev/qfe:1 - ether - -
start

# cat /etc/llthosts
0 VXcluster1
1 VXcluster2

Will be started from /etc/rc2.d/S68llt

#cat /etc/gabtab
/sbin/gabconfig -c -n 2

GAB is started from /etc/rc.d/S92gab

test av LLT/GAB:
On system A:
#/opt/VRTSllt/llttest -p <port>
>receive -c <count>

On system B:
#/opt/VRTSllt/llttest -p <port>
>transmit -n <dest-node-ID> -c <count>
>exit

DISKHEARTBEAT: This can be done in 2 ways:
1) global, by GAB
2) pr. hagrp, its own resource , DiskGroupHB

1: needs 128blocks (64kb) of a disk
#hahpsetup c1t3d0 (reinitialize) Can still be used by VxVM
heartbeat slice 7, private slice 3, public slice 4

Settes i /etc/rc2.d/S92gab:
/sbin/gabdisk -a /dev/rdsk/c1t3d0s7 -s 16 -p a
/sbin/gabdisk -a /dev/rdsk/c1t3d0s7 -s 144 -p h

blocks 0-15: partition-table
blocks 16-143: Seed port a
blocks 144-271: VCS port h

/etc/VRTSvcs/conf/sysname holds "the name of the node" this does not need to be the same as 'nodename' but why not?

#cat /etc/VRTSvcs/conf/config/main.cf
include "types.cf" (Has to be copied from /etc/VRTSvcs/conf
cluster <clustername>
snmp <clustername>
system VXcluster1
system VXcluster2

Example of a CONFIG:
Making a servicegroup, imports a diskgroup, starts a volume, mounts it and share it

Machines: VXcluster1, VXcluster2
cluster: VXcluster (193.216.23.205)
Volume: Vol01, dg= DataDG
Mountpoint: /export
ha(service)-group: hanfs

VXcluster1# haconf -makerw
# hagrp -add hanfs
group added; populating SystemList and setting the Parallel attribute recommended
before adding resources

# hares -modify nfsSHARE Enabled 1
# hares -modify nfsSHARE PathName /export
# hares -modify nfsSHARE OnlineNFSRestart 1
# hares -modify nfsSHARE Options " -o rw,root=VxConsole"

# Finnished with config, make links and mountpoints:
# mkdir /export
# hares -link nfsIP nfsnic
# hares -link nfsVOL nfsDG
# hares -link nfsMOUNT nfsVOL
# hares -link nfsSHARE nfsIP
# hares -link nfsSHARE nfsMOUNT
# hares -link nfsSHARE nfsNFS

#haconf -dump -makero

- Resource MultiNIC will do network-failover (like nafo in SunCLuster)
