Hello,
Although I haven't received any feedback, but I would like to share what I have just completed on the server.
Request from DBA: to grow /opt/oracle in a 4-node Veritas Cluster.
My question: how do I grow vxfs file system in a VCS environment since it's not using Veritas Cluster Filesystem, I can't grow the file system in master node and see it grow in all 4 nodes.
What I was thinking:
(1) is /opt/oracle under VCS control?
=> I went to check Veritas Cluster configuration file in /etc/VRTSvcs/conf/config/main.cf , noticed there has no mount point /opt/oracle defined, which means this file system is not under VCS control.
(2) To make sure, I login to all 4 nodes and noticed /opt/oracle is created in different disk groups
(3) Try to make sure again, I checked the size of /opt/oracle on all 4 nodes, noticed they are in different size
Therefore, I concluded serverb:/opt/oracle is "stand-alone" in serverb, I should be able just use simple "vxresize" to grow the file system.
Note:
1. vxdiskadm -> to initiate the 2 new SAN disks into serverbdg on serverb
2. vxresize -F vxfs -g serverbdg optoracle +XXg newdisk1 newdisk2

Hi,
I have 2 hosts with Veritas VxVM and VxFS (5.0 MP3_RP2). I need to use the application filesystem's luns from these 2 hosts and mount it on another 2 hosts that are running Solaris 9 09/05 and SVM.
Is there resources online or has someone tried this? (0 Replies)

vxbootsetup
vxbootsetup(1M) vxbootsetup(1M)
NAME
vxbootsetup - set up system boot information on a Veritas Volume Manager disk
SYNOPSIS
/etc/vx/bin/vxbootsetup [-g diskgroup] [medianame ... ]
DESCRIPTION
The vxbootsetup utility configures physical disks so that they can be used to boot the system. Before vxbootsetup is called to configure a
disk, the required volumes, standvol, rootvol and swapvol (and optionally, dumpvol) must be created on the disk. All of these volumes must
be contiguous with only one subdisk.
The -g option may be used to specify the boot disk group.
If no medianame arguments are specified, all disks that contain usable mirrors of the root, swap, /usr and /var volumes are configured to
be bootable.
If medianame arguments are given, only the disks that are associated with the specified disk names are configured to be bootable.
vxbootsetup requires that:
o The root volume must be named rootvol and must have a usage type of root.
o The swap volume must be named swapvol and must have a usage type of swap.
o The volumes containing /usr and /var (if any) must be named usr and var, respectively.
See the chapter "Recovery from Boot Disk Failure" in the Veritas Volume Manager Troubleshooting Guide for detailed information on how the
system boots and how VxVM impacts the system boot process. The vxmirror, vxrootmir, and vxresize utilities call vxbootsetup automatically.
If you use vxassist, or vxmake and vxplex to create mirrors of the root volume on a disk, you must run vxbootsetup explicitly to make the
disk bootable.
ARGUMENTS
medianame
Specifies the disk name (disk media name) of a VM disk that is to be configured as bootable.
