  • 1. System Backup
    Hi, I have a problem when I backup my system (/ /usr and /var) with ufsdump, I have an error : > DUMP: bread: dev_seek error: Error 0 > DUMP: bread: dev_seek error: Error 0 > DUMP: bread: dev_seek error: Error 0 > DUMP: bread: dev_seek error: Error 0 > DUMP: bread: dev_seek error: Error 0 > DUMP: Warning - block 1820510832 is beyond the end of `/dev/rdsk/c0t0d0s3' > DUMP: Warning - block 1621925620 is beyond the end of `/dev/rdsk/c0t0d0s3' I have called the SUN support and they told me that ufsdump should be used with unmounted FS. So for the system I must boot on CDROM or use the snapshot. It's not an hardware problem, because there is no message in /var/adm/messages, iostat is ok and fsck also (Dixit SUN support) I will do what SUN tells me, but I would like to know what method I must use with Solaris prior 8 on servers which cannot be stopped easily. Thank you Philippe PS : Sorry for my english !
  • 2. SCSI chaining question
    Hello NG, Not my day for anything going easily :-( I have a SCSI chain of a U60 and a U10 with a Multipak inbetween. The U10 is running S10_b69 and I am trying to jumpstart the U60 with the same OS (I would install the U60 by CD, but as per my earlier post, I cannot currently). I have used JET to configure the Jumpstart target, and all seems well until I try to boot the U60 over the net (boot net -s for testing)... bootp and TFTP work fine, the kernel is loaded, and all is going OK until I get a SCSI bus reset on c1 (the external SCSI chain), which then becomes a SCSI bus reset recursion, and the c1 bus is disabled :-( The U60 boots net OK though. I have tried configuring back in the c1 bus with cfgadm, but no luck :-( Now you may say "why don't you just unplug the external SCSI chain?" - well the drive that I am trying to install onto is in the Multipak :-( Short of opening the U60, oiking out the root disk, which is running S10_b63 (which I would like to keep, as S10_b69 has a few itchy bits), oiking out the target drive from the Multipak and making it the internal root disk in the U60... does anyone have any ideas how I might avoid the SCSI bus resets (or ignore them) on the external chain, and thus get the U60 to boot net OK and still have access to the external chain? Many TIA again, Beardy.
  • 3. Norwegian characters in vi solaris
    Hello I have som solaris 8 systems that has some scripts that has norwegian special characters. The problem is in the shell that we use the LANG setting is set to no_NO and that works in that shell. But when you use a program like vi it cannot read the characters. The same is when u use cat or more. So i was wondering if there was anybody with the same problem and if they had a solution on it. Regards Kalle

Clustering Sun: Sun cluster or Veritas?

Any of you have experience with Sun Cluster software and/or Veritas
Cluster?

I have worked with IBMS HACMP but none of the other solutions.  Even
that was fairly simple active/passive clusters, nothing too fancy.

Any pros/cons to running either Suns cluster software or Veritas' on
Sun systems? Probably either V880s or V1280s.  I have been looking at
the docs. on Suns site about Sun Cluster 3.1 but of course that is
just technical info, always best to hear from others with real
experience too :)

TIA.

Hey,

this is an endless discussion. I think, the Sun cluster is
fully integrated in Solaris (8/9/10), the Veritas cluster
has some more features and is easy to administrate.
Im certified on borh clusters, on smaller systems i prefer
Veritas on bigger systems (4800 and up) i prefer Sun cluster.

Worked with the older versions of sun cluster, not so familiar with the newer
versions of SUN cluster. Currently running both Veritas Cluster Server 2.0 and
Veritas cluster server 4.0.

Here is my 2 cents...

Sun cluster software must have been designed by some electrical engineer,
especially their heartbeat mechanism with the terminal server between the
multiple hosts,etc..(this is on the old clusters, not sure what it is like on
the new one.)

The overall design of the Veritas Cluster Server is just excellent. The way
their heart beat is designed and the way the hosts in a cluster communicate the
config information and maintain a consistent environment is just amazing. They
have their own proprietary protocol for the heartbeat and configuration
management over the heartbeat links ( LLT and GAB ).

The VCS configuration, is simple and easy to understand and easy to configure.
The administration GUI is excellent. Overall a great product. I have been
running VCS clusters for the last 4 years and have had no trouble with them.

Strongly recommend using VCS. Unless you have a very high end sun system and sun
has integrated some of the hardware failover into the cluster design for the
15K, 10K etc range of systems. I am not familiar with the high end systems and
won't be able to weigh in the benifits of the proprietary integration that sun
has implemented on the higher end systems. ( This is probably the reason why
another gentlemen who posted a reply to your message mentioned using sun cluster
if it is a high end sun system. )

For a 440/880/1280 VCS should kick ass, without any problems.

Sun Cluster 3.x is completely different to Sun Cluster 2.x. There are more
differences between the two versions than there are similarities.


The heartbeat stuff, as well as the need to have a terminal server is all
gone with Sun Cluster 3.x


"proprietary integration" ? Cluster on the high-end machines works in
exactly the same way as it does on the lower-end machines. There's nothing
special in the standard hardware or Solaris which acts differently.

There is one specific product which can have an impact on cluster configs,
being the WildCat interconnect boards, but that's an extra which is
just for better performance - it's neither required, built in, or used
in a standard HA cluster config.


Ditto Sun Cluster.

Obviously I'm a bit biased towards SC, and I've never actually run VCS
in anger, but I suspect either will do the job you're after without
any poblems.

Sun Cluster has the advantages of single-vendor support (same vendor
for OS, hardware and cluster) as well as tighter integration with the
OS.  VCS has the advantages of slightly more flexibility (although
this is both an advantage and a disadvantage), cross-platform
administration (but ask yourself if that's really an advantage - it
depends on the environment).

Personally I'd recommend SC3, but like I said, I'm a little biased  -
especially as I've installed 9x 2-node SC3 clusters in the past 2 weeks :)

At the moment being sysadmin for 2x SC3.0 system running on 6800's and also 
busy installing VCS 4.0 on 2xV480.
I like VCS much more, resource dependecies are much clearer in VCS, 
installation is easier, GUI's are better (for those that use GUI's). AFAIK 
you can download them both. Just pick 2 old machines and cluster them and 
see what you like best. If you can't download Veritas, contact them or a 
reseller and they can give you an evaluation version.

Good luck in choosing,

Marc 



Similar Threads:

1.Sun Cluster + QFS or Sun Cluster + Veritas

Right now I've got some 3.5 Veritas Clusters running Oracle8
that are due for an upgrade.

I'm playing around with the idea of getting rid of all of
our Veritas software and replacing it with Sun software
(since cluster is now free).

So it would be:

Solaris 10 (01/06 HW release, latest patches)
Sun Volume Manager
MPXIO
QFS
Sun Cluster 3.1

I've used Veritas for so long now & am weary of mixing it in
with Sun Cluster.  Ideally - I'd like to just go with one vendor
for my clustering.

Is MPXIO comparable to DMP?  Are people actually running Sun volume 
manager under production Oracle DB's?  I've used SVM for mirroring
boot drives on web servers and app servers but never in the database
tier.

I've read that QFS can do the volume management all on it's own -
is that what people are typically using with Sun Clusters?

I'm reading the FAQs and white papers right now but would love to
hear from some people with real world experience with the stuff.

4.Problem during Veritas VM upgrade on a Sun Cluster 3.0

Hello!


I have been upgrading Veritas Volume Manager 3.2 to 3.5 on a Sun Cluster 3.0
node. This is what I did:

- boot the node into single-user nocluster
- install patch 110648-33  :  should enable SC 3.0 to support VxVM 3.5
- reconfiguration boot
- back to single user nocluster mode, performed the VxVM upgrade according
to the manual method described in the "VERITAS Volume Manager 3.5
Installation Guide" pages 58 through 61.
- after another reconfiguration boot, I get this ginormous amount of
messages on the console:

5.SUN Cluster mount Veritas Volume as raw-device

Hello,

i must mount a Veritas Volume on a Mountpoint in SUN Cluster 3.1. The 
Volumes are create from Veritas in the Diskgroup and now  i want mount the 
volume at a mountpoint, but if i have mountet the volume, i found a ufs 
Filesystem on the volume, but i need a raw-device.
Can anyone help me, please. I think that i have little mistake in my doing, 
but i don't see it.

cheers feranna
