Veritas VM vs. Sun VM

Is there still a big performance hit when using the Solaris 9 VM as opposed to the Veritas VM (no vxfs, just strictly disk management on some A1000's)?
I saw the older forum post comparing Solaris 8 (UFS w/Solstice) but haven't seen much in the way of the Sun VM. Any real-world admins like to comment?

^Bump for great justice?

Storagetek 6140 - chunk size? - veritas and sun cluster tuning?

hi, we've just got a 6140 and i did some raw write and read tests -> very nice box!
current config: 16 fc-disks (300gbyte / 2gbit/sec): 1x hotspare, 15x raid5 (512kibyte chunk)
3 logical volumes: vol1: 1.7tbyte, vol2: 1.7tbyte, vol3 rest (about 450gbyte)
on 2x t2000 coolthread server (32gibyte mem each)
it seems the max write perf (from my tests) is:
512kibyte chunk / 1mibyte blocksize / 32 threads
-> 230mibyte/sec (write) transfer rate
my tests:
* chunk size: 16ki / 512ki
* threads: 1/2/4/8/16/32
* blocksize (kibyte): .5/1/2/4/8/16/32/64/128/256/512/1024/2048/4096/8192/16384
did anyone out there some other tests with other chunk size?
how about tuning veritas fs and sun cluster???
veritas fs: i've read so far about write_pref_io, write_nstream...
i guess, setting them to: write_pref_io=1048576, write_nstream=32 would be the best in this scenario, right?

Hi
You cannot dynamically resize filesystems unless you have some disc managagement software
running ( eg Solstice Disksuite, Veritas Volume Manager ).
If you do not have disk management software, you will probably have to dump all the filesystems
to tape or another server using something like ufsdump, repartition your disk and then restore the
filesystems back.
You can find good FAQs on Disk Suite or Veritas at docs.sun.com.

Share a disk between 2 servers?

We have a situation where we're thinking of mounting a LUN on our SAN to 2 hosts, where one would have a writeable filesystem & the other read-only. Would save us having 2 copies of the same data. Right now both Sun servers are running Solaris 9.
If the writing host puts all the data on the filesystem, then the 2nd mounts it read-only and there is no change, no problem (we think). But, if the 2nd RO host has accessed a file recently so it's cached, and the 1st RW host modifies the file, and the 2nd RO host gets another request for that file, how does the 2nd system "know" the file has changed? Sorry for such technical terminology. ;-)
So, can we make this work or not? Thanks for any help/advice.
David Strom

Correct. UFS does not support multiple simultaneous mounts. Worse than some files being cached and not updated, some bits of the filesystem could be cached the same way. It's possible that two inconsistent pieces of the filesystem could be read in a way that would lead to a panic of the R/O machine.
To do this right, you'd need to access the raw device and do your own arbitration and disk format (like Oracle RAC), use NFS from one host, or use a filesystem that supports multiple simultaneous mounts (eg. Veritas Cluster Filesystem, Sun QFS, ADIC StorNext)

Cluster with Solaris for Intel?

Simple question: Is this supported? Is this possible? Do I need anything
else beside the Media CDs or Solaris 7/8?
The idea of this is to let our students try out HA. We don't have
any Sparcs left for this purpose, but we have lots of PCs.
Thanks,
Harald Backert

Clustering is very dependant on the hardware.
The Sun Cluster solutions uses Sun's standard server and
storage product. Therefore, it is NOT support on Intel.
If you need it on the Intel platform, I am sure Intel has its
own clustering solution.
To setup a cluster solution, you will need, beside the OS, Volume
management software(Solstice DiskSuite or Veritas Volume Manager),
Sun Cluster Software(Sun Cluster 3.0 is the latest) and others.
For the complete list, go to:

As our system is one of critical systems and I'd like to confirm that I can follow up this procedure without doing harm things to our system.

No problem Jeff :)
I took a look at the Veritas doc and you're right it does seem to cover everthing.
Has the vxconfigd core dumped since the start? ie from the moment it was installed?
I have installed VXVM 4.0 with Solaris 8 but without the ASL and this worked ok, I know that's not much help to you but I am not sure the ASL will help. Mind you I have not installed it with Sun Cluster 3.0.

Veritas required for Oracle RAC on Sun Cluster v3?

Hi,
We are planning a 2 node Oracle 9i RAC cluster on Sun Cluster 3.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with LUNs etc, then why do we need to have Veritas Volume Manager (VxVM) if all the LUNS are configured at a hardware level?
2)
Do we need to have VxFS? All our Oracle database files will be on raw partitions.
Thanks,
Steve

> We are planning a 2 node Oracle 9i RAC cluster on Sun
Cluster 3.Good. This is a popular configuration.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with
LUNs etc, then why do we need to have Veritas Volume
Manager (VxVM) if all the LUNS are configured at a
hardware level?VxVM is not required to run RAC. VxVM has an option (separately
licensable) which is specifically designed for OPS/RAC. But if
you have a highly reliable, multi-pathed, hardware RAID platform,
you are not required to have VxVM.
2)
Do we need to have VxFS? All our Oracle database
files will be on raw partitions.No.
IMHO, simplify is a good philosophy. Adding more software
and layers into a highly available design will tend to reduce
the availability. So, if you are going for maximum availabiliity,
you will want to avoid over-complicating the design. KISS.
In the case of RAC, or Oracle in general, many people do use
raw and Oracle has the ability to manage data in raw devices
pretty well. Oracle 10g further improves along these lines.
A tenet in the design of highly available systems is to keep
the data management as close to the application as possible.
Oracle, and especially 10g, are following this tenet. The only
danger here is that they could try to get too clever, and end up
following policies which are suboptimal as the underlying
technologies change. But even in this case, the policy is
coming from the application rather than the supporting platform.

Veritas vs Sun Disk Mgmt. regarding DG portability.

Veritas allows Disk groups to be moved between hosts. Is this feature available in Sun's native suite? If so, has anyone deployed this in production and what is your feelings about it. If we run SUN's native disk mgmtm suite we can save thousands of dollars, but I need to gage the worthiness and maturity of product vs. Veritas for our SAN implementations.
Thanks
Patrick

The ease of deport/import with VxVM is one of the areas where I think VxVM has a significant advantage over SDS/SVM.
You can always do a "recreate" style import, but that assumes you have the old configuration and requires a bit of effort.
ZFS will offer an improved level of portability (similar to how VxVM works), but will not be available as a production release until Solaris 10 Update 2.

Is Veritas- or Sun Cluster needed for RAC in a Solaris Environment

Is a Veritas- or Sun Cluster needed for RAC in a Solaris Environment?
Does anyone know, when OCFS will be available for Solaris?

You don't need Veritas Cluster File System, but until OCFS comes out for Solaris you need to think about backups. If you've not got a backup solution that can integrate with rman for an SBT device then backups become more tricky.
If you use ASM then you can take a backup to a "cluster filesystem" (although ASM is raw partitions think of it as a cluster filesystem), that both nodes can see. BUT you then need to get these to tape somehow, unless you've got NetBackup et al. that support RMAN and can backup direct to tape you're more stuck.
Too many people don't think about this. You could create an NFS mount and backup to this from the nodes.

Sun c4 and veritas netbackup 6 mp4 installation

Hello, please help me!
We have SAN with 2 st6140 and 3 broacade 200e switch. One site is: two 200e and 3 linux hosts, other site is: v240 server (one FC port) with solaris preinstalled and installed Veritas NetBackup mp4, 1 200e switch, Sun C4 library whith FC ports.
On second site I connected C4 FC host port to the 200e swith, FC port on v240 also connected to the 200e switch.
Can you describe me a common porcedure to configure correctly a server with Veritas and C4?
I cant add "device" in veritas Administration console now, because it cant see nothing.
How i have to connect C4 and Veritas server to SAN correctly ?

create a soft zone on your brocade , with your C4's FCs ports and your Netbackup Master server, for Netbackup use version 6.5 , not 6.0
once you activate your zone, run cfgadm -al -o show_FCP_dev, you should be able to see your paths, one path or more paths from your server, two or more from your C4 libraries' fabrics, netbackuop 6.5 is very clean and installed , to be able to recognize your drivers ...once the software installed, go to your GUI, to configure device...
Also, use the latest version of Solaris10 on this..it is much cleaner to work with netbackup 6.5

Sun QFS cluster file system with Veritas Volume Manager

Hi,
Can someone confirm whether it is possible to create a Sun QFS cluster file system (for Oracle RAC datafiles) using a VxVM volume?
Or must we use Solaris Volume Manager with QFS?
Thinking of storing the static part of the Oracle RAC DB on VxVM raw devices, and the dynamic part on a QFS file system to avoid the overhead of constantly adding new raw devices when i want to create datafiles.
Thanks,
Steve

Steve,
No, shared QFS is only supported on Solaris Volume Manager. I've not heard of any plans to test it on VxVM.
Why not keep the static parts of the DB on raw SVM devices? Why keep them on raw devices at all?

Veritas volume replicator under sun cluster

Hi,
Can we use VVR under sun cluster server? We want to replicate data on sun cluster nodes to a seperate box which is not part of the sun cluster. Is there any special configuration needed?
Thanks and appreciate any response.

Don't forget you will also need to obtain a VXVM Cluster functionality license to use VXVM in a Sun cluster, which is a separate license key to the base VXVM.

Sun Cluster 3.0 Veritas Volume manager add a new file system

Hello people recently in need add a new file system to my Solaris cluster installation ( with oracle 8), but I have some dudes about the correct procedure for this.
I put the procedure:
Ok:
/etc/vx/bin/vxdisksetup -i c4t1d1
/usr/sbin/vxdg -g space-dg adddisk space07= c4t1d1s2
/etc/vx/bin/vxdisksetup -i c4t1d2
/usr/sbin/vxdg -g space-dg adddisk space08= c4t1d2s2
/usr/sbin/vxassist -g space-dg make vol3-space 70686720 layout=striped stripeunit=128 alloc="space07 space08"
mkfs -F vxfs /dev/vx/rdsk/space-dg/vol3-space
In this point I update my dginfo in the active node of my cluster
scconf -c -D name=space-dg,sync
Add in all node /etc/vfstab)
/dev/vx/dsk/space-dg/vol3-space /dev/vx/rdsk/space-dg/vol3-space /space_mount/vol3-space vxfs 2 no -
Made the mount point in all nodes:
mkfs /space_mount/vol3-space
mount the file system in active node.
mount /space_mount/vol3-space
use sccheck.
My dude is about is about Storage plus resource (space-grp:space-storageplus-res:FilesystemMountPoints) because this don�t have the new mount poing, if I must put the new mount point in this property using: scrgadm because my cluster has HAStorage-plus.
What is the optimal form? If I must use scrgadm I can modify this property (FilesystemMountPoints) with
(scrgadm -x FilesystemMountPoints =value) ??
Or must recreate space-storageplus-res????
Thanks for you time and sorry for my English.

Thanks I made sucessuly.
The final procedure:
1 create the disks in vertias (not the volumen)
2 if you add new disk, recreate the did
scdidadm -L
scdidadm -r (must exec in all nodes)
scgdevs (in all nodes)
3 Disable the resouces using scswitch -n -j (the resouce)
in my case we disable all resouce but NOT the resouce group. (only exec in one node)
Make the new file system. :-D. makefs. (in one node)
4 make the new pount mount in all nodes.
5 insert the new line in vfstab (remenber the mount at boot to set to no)
scrgadm -pvv | grep "FilesystemMounPoints="
6 You must put the "FilesystemMounPoints=" in same orden in vfstab
I use the sunplex (more easy) ..
Renable to online your resources.
Test to switch over to another node.
The new filesystem may be automaticaly mounted.
Bye an thanks for the help

Upgrade from Solaris 8 SPARC with Sun cluster 3.1u3 to Solaris 10 SPARC

Dear All,
We are planning an upgrade of the OS from Solaris 8 SPARC to Solaris 10 SPARC on a two-node active-standby clustered system.
The current major software we have on the Solaris 8 system are:
1: Sun Cluster 3.1u3
2: Oracle 9i 9.2.0.8
3: Veritas File System Vxfs v4.0
4: Sun Solaris 8 2/04 SPARC
Any pointers as to what sequence and how the upgrade should be done?
Thanks in advance.
Regards,
Ray

yes I know it can be quite complicated and complex, but Sun provided us with a detailed documentation, at least in our case Solaris 9 to 10 it was very helpful.
You might get better help in the cluster forum http://forums.sun.com/forum.jspa?forumID=842
