I've had a VXFS filesystem get corrupted and now it won't mount.
Can I run a fsck -y on the raw disk device or should something be
done within veritas? Veritas does not see the disk at the moment. (2 Replies)
Hi there,
My task is to replace the two 73 G disks with two 143 G disks , which has vxvm 4.1 running on it. I would like to know whether the steps iam following are correct.
1. Break the sub-disks, plexes of the root mirror.
2. Remove the sub-disks,plexes of the root mirror.

I am trying to write a kornshell script that will automatically create veritas disk groups. However, the only utility that I can find that will create the diskgroup is vxdiskadd, which prompts with interactive questions. I've tried to pass the answers through to vxdiskadd, but I receive the... (0 Replies)
hi all
i am using vxvm 5.1 on my sun blade 150 which is running with solaris 5.10. When i give the command "vxdisk list" it gives the following output

I installed new internal disks in my p570. They will be part of a new AIX vg. Unfortunately, we have Veritas Volume Manager running on this AIX 5.2 ml 10 box. Veritas has grabbed control of the disks. I want AIX LVM to control the disks.
I cannot get these disks free of Veritas:

Hi,
I`m on SunFire480R with Solaris 10. Disk in rootdg group failed, so it was replaced. However, I cannot make Veritas initalise the replaced disk:

Need help getting all disk devices back on node 2 the same as node 1.
Recently Veritas and/or Sun cluster got wrecked on my 2 node Sun cluster after installing the latest patch cluster. I backed out the patches and then node 2 could see only half of the devices and Veritas drives (though format... (0 Replies)

vxdmp - Veritas Volume Manager multipathing disk devices
DESCRIPTION
Multipathed disk devices in Veritas Volume Manager (VxVM) represent virtual devices with one or more physical access paths to a physical
disk. The Multipathing feature provides disk access reliability by dynamically switching to another physical path if there is a path fail-
ure.
Every disk that is visible to VxVM is represented by a multipath device node in the /dev/vx/dmp and /dev/vx/rdmp directories for block type
and character type interfaces. A simple disk is represented by a multipath device having one physical path, whereas a disk that is part of
a multiported disk array is represented by a multipath device with many device access paths depending upon the type of the disk array.
VxVM uses standard disk device naming conventions to name multipath devices. For example, if there is a disk device with two physical
access paths such as c1t0d0 and c2t0d0, the multipathing device node for this particular disk is created under /dev/vx/dmp and /dev/vx/rdmp
as c1t0d0 or c2t0d0.
To provide multipathing, VxVM maintains an internal database of all the multipathed devices detected by the system and their respective
paths. The database is created at system boot time. When disks are added or removed from the system, VxVM provides support to reconfigure
the multipath device database to reflect new states of the hardware, while the system is online.
To reconfigure the DMP database, run ioscan followed by insf, and then invoke vxdctl enable (see vxdctl(1M)).
The various access paths to a multipathed device can be seen by using a vxdisk command (see vxdisk(1M)). These commands open the multi-
pathing configuration device /dev/vx/dmpconfig to obtain the required information about the various paths to a multipathed device and their
states.
VxVM also provides the facility to enable or disable a disk controller. This feature can be used to stop all I/Os through a particular con-
troller to perform maintenance operations on it. Use the vxdmpadm command to do this and also perform other operations on the multipath
device database.
VxVM can provide notification about events that occur in the DMP database due to a change in hardware. See the vxnotify(1M) man page for
more information.
VxVM is capable of multipathing both Active/Active and Active/Passive disk arrays.
