  • 1. upgrade Solaris 7 to 9
    I have a machine runnig Solaris 7, just wonder if it is possible to upgrade directly from Solaris 7 to Solaris 9? The disks on the Solaris 7 machine is mirrored with DiskSuite, when I upgrade it, do I need to break the mirror and take the disk out from the DiskSuite or even remove the DiskSuite package? What is the senario of upgrading when the disks are under DiskSuite? Thanks for advice!
  • 2. Solaris 10 download
    When I try and download Solaris 10 Sun has some questions that are required fields but I can seem to get past one question I do not know the answer that sun is looking for Registered Licenses used for: a. *Commercial/Production: b. *Development: c. *Education/Research: d. *Evaluation: e. *Personal: What sort of answer is sun looking for me to enter into the text boxes next to these selections
  • 3. Disk labels (c0d0 & c0d1 => c0d2 & c0d3) wierdness
    This is not new or unusual for me, but I was just wondering if I could, or even should, change the disk labels when I install Solaris. I've got a W2100z with two U320 SCSI disks and two cdrom drives on the IDE interface (one on each channel, primary/master). SATA in BIOS is disabled as there are no other disks in the system. When I install Solaris (10 GA, 10u1, Nevada - doesn't matter) only disk labels c0d2 and c0d3 are available. c0d0 and c0d1 never show up. I've used Solaris for many months simply installing on disks "2" & "3" without any problem but some programs, iostat for example, are not as easily useful not having c0d0 and c0d1 populated first as those drives are displayed first. Is there any way to remedy this and have my SCSI hdds show up on the first two IDs "0" and "1"? I would almost wonder if this is a partitioning problem. Each 74GB drive has one dedicated partition to Solaris on the fist partition. TIA

Sun Clustering vs. VCS

Postby eizner » Wed, 17 Sep 2003 05:04:40 GMT

I'm sure it has been discussed already but I could not find any
helpful thread.
I need to implement HA (Fail Over) solution between two SUN servers,
probably 2x480R + StorEdge S1 Array
I'm considering to use either

1)DiskSuite + Sun Cluster V
or
2)DiskSuite + VCS.

I'm looking for comparison , advantages and disadvantages for #1 and
#2

Thank you
C.E.

OK.  Here is my contribution....



     This is less expensive in small systems.

     BTW the latest SunCluster is version 3.1
     It is also more complex to set up with the qourum disk.
     It is a kernel level cluster implementation.
     Can Use VERY FAST system interconnects ( SCI cards / SUNFire LINK, several
     100 Megabyte/s up to 2.4 GigaBytes/s )
     This is nessesary for LARGE Oracle RealApp clusters.

     can grow to 8 nodes.



    You dont want to do that. If you go for Veritas go the whole way
    and implement  "Veritas Foundation suite HA" which
    is VCS + Veritas Volume manager.

    VCS and VVM setup can be done almost entierly with GUI's
    It is a mixed Kernel/userland implementation. Some Kernel drivers,
     but the main HA-daemon process runs as a REAL-time user proc.
    Fastest usable interconnect is Gigabit ethernet.

     Can grow to 32 nodes.

In article < XXXX@XXXXX.COM >,



OK, rethink this architecture. The S1 will become a single point of failure.
Atleast consider the SE3310 with redundant power supplies, connections 
and controllers.
Will add only a few % to the total cost.


This seems like a disk performance insensitive solution and I would choose 
the simplest and cheapest solution, which would be #1 in this case.

I should have said that:
What is Sun Cluster V? V3.1
What version of Solaris are you going to use? Solaris 8 + DiskSuite 4.1
Number on nodes:                        2 (one in stand by)
Storage size:                                50Gb
Potential growth within 12 month: 100Gb

Thank you
C.E.

At the very minimum consider two S1 Arrays and mirror between them.
Even better would be to use a FC array like an A5200 or 3310FC.


Last I heard, using SDS with VCS (other than for the root mirror) is not
supported by Veritas.  Foundation Suite HA (VxVM+VxFS+VCS) would be best, but
you could probably get by with VxVM+VCS and use UFS for your filesystems.

What applications do you intend to cluster?

There are other Cluster products

I can get "disk system ds2405" (HP). Will it work?

I don't see that array listed on the VxVM 3.5MP2 HCL [1].  While it may work,
you will not have DMP (multipathing) and Veritas probably will not support your
configuration.

3.Cluster (VCS & Sun on Solaris): Install application package on shared disks

Hi, There

When installing application package on shared disks in a cluster
environment, the node (Node A, let's say) from which you install keeps
package (and patch) information. However, Node B doesn't have such
information even though in a failover situation, it still can see the
package binaries.

Since we can't install a local copy on each node due to space
restriction, is there a way (or workarount, or fool node B) to update
node B on pkginfo wheneven the application has package/patch installed
on node A?

Thanks a lot.

4.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.

5.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.
