RAID-1 for root/swap on Solaris 10 x86

OK, now that I have solved my problem with the update manager I am in the process of trying to create RAID-1 volumes for root and swap. I am working my way through the process by following the procedure in Solaris Volume Manager Administration Guide. I have run into a few errors in the doc, e.g. referent to using installboot as opposed to installgrub.
Now I am trying to create my new volume using the Enhanced Storage tool within the Solaris Management Console. I get as far as trying to create the new volume (RAID-0) with the root slice in it but it fails with metainit telling me that the slice is already mounted on /. (No kidding -- that is the whole idea.)
Does anyone have a working procedure to create RAID-1 for root and swap?
(BTW, I am trying to do this from the doc and admin guides without stealing time from folks on the list here but I just keep running into walls.)
(Once I get that done I hope to use zfs for the rest of the storage.)

I am attempting to set up RAID-1 (mirroring) for root and swap. I am attempting to work from "Solaris Volume Manager Administration Guide," Part No: 816�4520�12. (Same place you pointed me except I downloaded the pdf so I could page through it faster.) On page 105 you will find an entry for "Create a mirror from the root (/) filesystem," which directs you to page 122, "�x86: How to Create a RAID-1 Volume From the root (/) File System by Using DCA�.
I have two identical 300GB PATA drives with 20GB root/boot and swap partitions. The slices are all identical as to size and location, i.e. c0d0s0 is root and c1d0s0 will be the mirror for root. (I will use "mirror drive" to refer to c1d0.
Proceeding through the steps I have verified I can boot the mirror. I have created the slices. I have used fdisk to put the master boot block on the mirror drive. I have installed grub on the mirror drive.
At this point I am on step six which reads:
"Create a new RAID-0 volume on the slice from the previous step by using one of the following
methods. Only the single slice can be included in the RAID-0 volume. " At that point I decided to try to proceed using the Enhanced Storage Tool from smc.
As to RAID-0 vs. RAID-1, it is my understanding from the doc that one must first create the RAID-0 volumes, each containing just the single slice, one for each of the two volumes that will be combined to make the RAID-1 mirror, hence my comment about RAID-0.
I see your point about using the -f option to force the creation of the volume for the mounted root filesystem. One would think that, if they included the option of using the Enhanced Storage Tool that perhaps it might work. (I did not see a way to force the creation of the RAID-0 volume.) Certainly using metainit with the -f flag makes sense.
Next step will be to go back and punt EST in favor of using metainit from the command line.
I get the feeling that no one at sun is actually trying what is in the manuals to ensure correctness.

Install error for Oracle 10g on Solaris x86 64-bit. NETCA won't run

Hi All,
I'm installing Oracle 10.2.0.1 on Solaris x86 64-bit. I run the Oracle installer and all runs well until the NETCA portion of the install. It then errors (error file below). When i attempt to run NETCA outside of the installer i'm getting the same error output. I have verified my OS version and that all dependent packages are installed. I'm not sure what is causing this. Any help would be greatly appriciated.
thanks, dave

Bad entry in /etc/password for root

I had a feeling that it wasn't a good idea to change the default shell for root. Tried it anyway because I know how to get myself back in on other Unix versions - Well I can't log in as root anymore. Can't even su to root (with or without '-'). b - s from the boot interpreter fails as well.
What I'd like to try now is to boot in single user mode from CD and mount my hard drive and get to the /etc/passwd file.
Does somebody has the exact procedure (or a better one)?
Thanks
Jim Theriault.

This document outlines several methods to boot a Solaris 2.6/7 x86 system up to single-user mode. Most of these methods will work for earlier versions of Solaris x86 as well.
Booting Single-User From CDROM Using the Device Configuration Assistant (DCA) on the Hard Drive:
1). Power the system on.
2). Insert the correct version Solaris Software cdrom for your system.
OPTIONAL: If there is a boot loader in operation on your system, select the Solaris partition as the partition to boot from.
3). After the "Solaris Secondary Boot Loader" and "Running Device Configuration Assistant" messages appear, hit the 'esc' key where prompted to do so.
4). At the "DCA intro screen" hit F2 (F2_Continue).
5). At the "list of devices found" hit F2 (F2_Continue).
6). At the "list of available boot devices" select the CDROM as the device from which to boot a Solaris kernel.
7). At the screen where you are prompted to select 1, 2, or 3 for what type of install you wish to do, enter 'b -s' instead of a number.
This will bring the system up to single-user mode from the cdrom.
Booting Single-User From the CDROM Using the Device Configuration Assistant (DCA) Floppy:
1). With the power on, insert DCA floppy, then the correct version Solaris Software cdrom for your system.
2). At the "DCA intro screen" hit F2 (F2_Continue).
3). At the "list of devices found" hit F2 (F2_Continue).
4). At the "list of available boot devices" select the CDROM as the device from which to boot a Solaris kernel.
5). At the screen where you are prompted to select 1, 2, or 3 for what type of install you wish to do enter 'b -s' instead of a number.
This will bring the system up to single-user mode from the cdrom. It should be noted that even though there are fewer steps, this normally takes much longer than running the DCA from the hard drive.
You can then mount the root partition to /a (a standard mount point on the cdrom) and edit /a/etc/passwd

SGD Solaris x86 no SecurID support

Hi,
Is there no support for RSA SecurID on Solaris x86. SGD version 4.2. It seems as if the RSA SecurID module is just not installed (with security pack!).
Regards,
Arno Staal
Divider B.V.

Call or write RSA and let them know you want SecurID for Solaris X86. There is no excuse they don't release this as it is exactly the same code as Sparc, just a simple recompile.
I just spoke to them and they are checking on it for me.

How so I protect my root file system? - x86 solaris 10 - zfs data pools

Hello all:
I'm new to ZFS and am trying to understand it better before I start building a new file server. I'm looking for a low cost file server for smaller projects I support and would like to use the ZFS capabilities. If I install Solaris 10 on a x86 platform and add a bunch of drives to it to create a zpool (raidz), how do I protect my root filesystem? The files in the ZFS file system are well protected, but what about my operating system files down in the root ufs filesystem? If the root filesystem gets corrupted, do I lose the zfs filesystem too? or can I independantly rebuild the root filesystem and just remount the zfs filesystem? Should I install solaris 10 on a mirrored set of drives? Can the root filesystem be zfs too? I'd like to be able to use a fairly simple PC to do this, perhaps one that doesn't have built in raid. I'm not looking for 10 terabytes of storage, maybe just four 500gb sata disks connected into a raidz zpool.
thanks,

You could use Sun Volume Manager to create a mirror for your root filesystem.
The files in the ZFS file system are well protected, but what about my operating system files down in the root ufs filesystem? If the root filesystem gets corrupted, do I lose the zfs filesystem too?No. They're separate filesystems.
or can I independantly rebuild the root filesystem and just remount the zfs filesystem? Yes. (Actually, you can import the ZFS pool you created).
Should I install solaris 10 on a mirrored set of drives?If you have one, that would work as well.
Can the root filesystem be zfs too?Not currently in Solaris 10. The initial root support in OpenSolaris will require the root pool be only a single disk or mirrors. No striping, no raidz.

Help with evaluation for Solaris x86

Hello,
I would like to evaluate Oracle Identity Manager and Access Manager products at the latest version possible -- the host system(s) are Solaris x86 (SunOS .5.10) Unfortunately, I am having a bit of trouble compiling the list of packages/versions to achieve this for this platform. For instance, on the downloads page it appears that OIM is not available for Solaris x86, not even in older versions(?)
Thank you in advance,
Scott

Hi Scott,
I'm pretty sure that x86 Solaris is not yet certified to run the Identity Management suite. I've been involved in an evaluation process and we ran it all on RedHat Enterprise Server Release 4 Update 5, without too many problems.
cheers,
James

Core 2 Duo and solaris x86 11/06 works for me

This is FYI, since I seen (and posted) problems, but I haven't seen the solution posted.
I have successfully gotten solaris x86 11/06 to install and run on my core 2 duo machine. I had tried solaris x86 06/06, but I could only run in 32bit mode until patch 118855-19 was installed. It looks like 118855-33 is the baseline for 11/06.
With 06/06 I had to edit the grub command and add " kernel/unix" to the end of the 2nd line. This would force 32 bit mode rather than 64 bit. If I tried 64 bit, it would enter an endless reboot cycle. Once I installed the patch to 118855-19 I could run solaris 10 06/06 in 64 bit mode without issue.
Again, since solaris 10 11/06 is at 118855-33, it runs on my core2 machine straight from the install.
Hope this helps

On a laptop there is little point with running a 64-bit operating system unless it physically has more than 4gb of ram, or if you are processing datasets exceeding 4GB of ram. Unless you're into assembly or use Solaris for some reason to manipulate media, little is to be gained by using 64-bit versions if anything. The increased pointer, integer, and padding causes more memory to use for the same software, most software on 64-bit operating systems runs in 32-bit mode because there is no need to have 16 exabyte memory addressing capability for anything but media encoders, giant databases, or extremely bloated single-threaded software. Sun Java Creator takes a heck of a lot of ram, but even at peak it's still under 4GB. If you move files bigger than 4GB, the ability to memory map all 4096MB might have less overhead on a 64-bit operating system, but generally from an end-user perspective, especially on a fast Intel or Opteron system, you won't notice the difference much. Solaris is bi-arch, a large chunk of Windows Vista and XP x64 is bi-arch, and most of FreeBSD and Linux are bi-arch in 64-bit versions, as I said, no point in making everything 64-bit. 64-bit device drivers is an issue for every OS, you should stick with 32-bit on a laptop, and hold off on desktops unless you need extended assembly registers available only in 64-bit mode.

"Oracle Enterprise Manager 10g Grid Control *Management Agent Release 1* (10.1.0.3) for Solaris *x86*"

Please throw me some more meat on that bone. I'm still waiting for my Metalink access. (i.e., can you cut and paste the note text onto this forum message.)Sharing(Cut&Paste) Metalink Notes is not legal.

Support for JRockit for WebLogic 10.3 in Solaris x86

Hi All,
I am trying to install JRockit Mission Control 3.1.2 in a Solaris 10 x86 platform.
For Solaris Spark I know there is a special distribution.. For Solaris 10 x86 I am trying to install the generic linux version.
When I try to install the jrmc-3.1.2-1.6.0-linux-ia32.bin I get the following error:
jrmc-3.1.2-1.6.0: Cannot find /lib/ld-linux.so.2
I also try with 64bit edition of the jrockit mission Control but I get a similar error but trying to find the /lib64/ld-linux.so.2.
Is Solaris 10 x86 supported? Or at least, is there a workaround to install it?
I find some site talking about JRockit for Solaris Spark, but seems to me that Solaris x86 is not supported...
Thanks in advance
Pablo

Hi,
The DTD used in "web.xml" should not cause any issue ...though it's the OLD "web.xml"...Please try to run the Following command to Generate the New Deployment Descriptors from the Existing Application:
Step1). Open a Command Window and Run "setWLSEnv.sh" or "setWLSEnv.cmd".
Step2). In the Command Prompt move to the Current Directory where you have placed your Application and then Run the Following Command
java weblogic.DDConverter -d NewDDs jamagent.war
Here Above Command Will read the "jamagent.war" War archive and then It will generate the New DDs in "NewDDs" directory...Which we need to replace with the OLD DDs present in our WebApplication..
