How to mirror soft partitions in solaris 10

I have created a few soft partitions on my disk using SVM and now wish to mirror the disk with the redundant one. At the time i give the metainit command to create the mirror, it gives me an error : invalid unit for the metadevice from which i have created the soft partitions.
Please help

Change active Partition in Solaris 10

I have installed Solaris10 and after Windows Xp, the boot loader disappear. The system Startup always by Windows Xp. I have installed Partion manager and I change Active partition to Solaris 10, Know the system Statup always by Solaris 10. Please tell me how I change active partition in Solaris (to set Windows XP active partition again ). Could I use fdisk ? and how?

1.Change the bios settings to boot from CD
2. Insert the Solaris Software CD 1
3. The procedures for installation starts , when it asks for the type of installation ie Interactive , jumpstart etc.
4. At this prompt type " b cdrom -s "
5. This will give you a root prompt
6. mount the disk root partition onto a temp mount point on cd
mount /dev/dsk/c0d0s0 /a
7. cd /a
8 . Run the format command
9 . Choose fdisk
10 . Follow prompts to make the WinXP the active partition
11. Save changes
12 . Reboot

Mirror boot disk with soft partitions

We've been investigating Solaris Volume Manager with Solaris 9 and have some questions. We currently use DiskSuite 4.2.1 to mirror our boot disks on Solaris 8. The fact that SVM is integrated into the kernel on Solaris 9 got us thinking. Here are some questions I would greatly appreciate answers to:
1. Is it possible to have your boot disk partitions (/root, /var, swap) be soft partitions and then mirror the soft partitions (so disk 1 you'd have 3 soft p's and on disk 2 you'd have 3 soft p's and create the mirror from them)?
2. What would the problems be with this? The major one we could foresee is not being able to see your /root, /var and swap partitions in the case of having to boot from the CD, but if SVM is in the Solaris 9 kernel, wouldn't that solve that issue. Is this a problem? Are there other issues/problems we're not thinking of?
3. Finally, is having your boot partitions be mirrored soft partitons a supported configuration from Sun?
Thanks,

Hi,

The reason the HDD is split into two partitions is so if there is an error with the OS, they can reinstall it without affecting the user files.
Makes sense in a way. But does this 'they can reinstall...' imply that you don't have the OSX Install DVD for your Mac ?
Cause you need that DVD for installing the BootCamp Drivers of it !
I do have admin, and I can re-partition my HDD, but I cannot touch the OS partition.
If I set it up like this: http://micmac95.fileave.com/HDD%20setup.png , by shrinking the USER partition, will I be able to install windows on the BOOTCAMP partition?
Personally I never tried this 'Shrinking one partition to make another partition' approach with BootCamp.
But, if you don't have one now is the time to make a complete backup of all the things on your Mac !
Before 'fumbling' with partitions I always make sure to have a backup.

How to create a separate /var partition on solaris non-global zone

Hi
I found no simple way to create a separate /var partition in solaris non-global zone.
I am using solaris 10 u9 and my root pool is zfs. My zone's zonepath is also separate zfs fs.
But, I do not know how to make the /var as a mountpoint of another zfs dataset since /var is not empty.
I also do not know if there is a way to install a zone with /var as a separate (outside '/') partition.
That will be really useful.
Any suggestion?
Thanks
Edited by: vadud3 on Sep 20, 2010 12:16 PM

I meant a separate zfs fs with mountpoint '/var' in a non-global zone.
I am insisting, because I do not want /var to fill up the '/' on non-global zone.
With default non-global zone installation, you cannot avoid that.
My zonepath itself is a zfs fs. I also have a zfs dataset provisioned to the non-global zone.
I cannot create a zfs fs out of that dataset and mount it as '/var' becasue by then non-global zone
already installed content on '/var'
I want the '/var' as a separate dir or mountpoint, the same reason global zone gives you that option during install.
Thanks

How to remove partition on solaris

Ultra Sparc-2. 2 Disks. 9GB, 18GB.
To use the soft partition tool, I upgraded to Solaris9. the OS is on first disk c0t1d0. So I run the format utility to format the whole second disk c0t2d0, hoping it will remove all the existing partition. However they are still there:
Part Tag Flag Cylinders Size Blocks
0 root wm 0 0 (0/0/0) 0
1 swap wu 0 0 (0/0/0) 0
2 root wm 0 - 7505 16.86GB (7506/0/0) 35368272
3 usr wm 0 0 (0/0/0) 0
4 var wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 - 7505 16.86GB (7506/0/0) 35368272
7 home wm 0 0 (0/0/0) 0
Is there a way to remove them explicitly? the size 0's are the result of my attempt to eliminate the with the modify command. Or do their existence really matter?
Ignoring them, I tried to create the metadatabase on c0t2d0 with the command, but get the failure msg below.
metadb -a -f c0t2d0s7
metadb: SunLab: c0t2d0s7: device size 0 is too small for metadevice database replica
What steps should I follow?

It's kind of odd though. Normally when you set the size to 0, it cleans up the rest and changes the tag to 'unassigned'.
In fact I just tested that and that's exactly what happens. Perhaps you're behind on patches or something? I would expect slices 3, 4, and 7 to have 'unassigned'.

for metadevice database replicaUmm, your output shows 0 blocks assigned to slice 7. So yes, it's too small.
You should only give slice 6 (or whatever) all but a few cylinders. Then give slice 7 those cylinders. I'd allocate about 12MB to it.
That way you have a small slice for your metadevice replicas and a big slice for most of the data.

Partitioning in Solaris 10

I have a SUN v240 server that has been installed and partitioned. I installed both disks under the system with little available free space left. One disk with 70 gigs dedicated to system and one dedicated to /usr and some home dir's. I was informed afterwards that I need a large Oracle partition dedicated to Oracle for spatial. Is there any way to partition "on the fly" with Solaris 10 so that the system remains in tact and I have 25 gigs of free space to set up a partition for Oracle?

Yes what your looking for is "soft partitions". By using soft partitions you can create and grow filesystems on the fly if space is available. Check out chapters 12 and 13 of the Solaris Volume Manager Administration Guide (link is below).

How to make the Partition on my laptop hard disc

Dear Sir
I purchased new HP lap top, I would like to partition on my hard disc.
Please give me the suggestion for how to take the back up for my new laptop its necessary or not and how to create the partition on my hard disc System information

Windows dome premium 64 bit
Hard disc size 640gb
4gb ram
Thanks and Regards

Perfect Solution to Problem:
Precautions:
1.Create your recovery DVD's from recovery partition before proceding, or order them from hp so as in case of any error or in worst case system can be set to factory restore.
2.BACK UP YOUR DATA.
3.FOLLOW ON YOUR OWN RISK , NO RESPONSIBILTY FOR DATA LOSS , SYSTEM CRASH, OR LOSS OF RECOVERY PARTITION.
4.Hopefully you have read this , if any consequences arises take it on your part , nothing to do with it, you can leave the rest of reding part if not ready,
THANKS FOR READING........
OOP'S you are here,,,,,,,,,then lets continue at your risk..........
Statement:
You are using this guide at your own risk. I don't take any responsibility for any problems.
Important informations !
Before you will do anything please create a set of recovery discs and back up all important data.
Both these steps will save you a lot of troubles if something will go wrong.
Resource:
From experience
Remember that if you will decide to use the recovery discs or the F11 option to restore the PC to its originalcondition, all partitions which were created by you will be lost and all the data which were stored on them willalso be lost.
Introduction:
Below screenshot shows pre-configured partitions on HP notebook with pre-loaded Windows 7.
As you see mounted HDD has four primary partitions:
C - partiton with the operating system.
HP_TOOLS - partition which allow to use diagnostic tools after pressing F2 on startup.
RECOVERY - partiton which allows to recover system by pressing F11 on startup.
SYSTEM - active partition which boots the operating system.
Here begins our problem. A standard partition table is only able to store information about four partitions.
This means that a hard disk could have a maximum of four partitions. The four standard partitions are oftencalled the primary partitions.
To deal with this limitation we may:
----> Delete hp tools partiton , and create new logical partion, BUT RECOVERY MEDIA SET HAVE BEENCREATED BEFORE......
PROCESS:
Note:
Please perform each operation individually.
Using several operations at one time may end with fatal error.
1.Hope you have your recovery media , recovery media dvd set and DRIVER DVD,if not then please get it first for safety..
2. Download and install MiniTool Partition Wizard Home Edition.
3.Please back all of your data on HARDDISK before proceding.......
4.Go to START> COMPUTER > RIGHT CLICK ON IT > MANAGE
5.A window opens, select disk management from it , given on left hand side....
6.It will display your harddisk partitions as displayed in image.....carefully locate HP_TOOLS Partition in given table.....
7.Right click on HP_TOOLS Partition and Delete it.........it will prompt for response say yes.........
8.Now must have left with 3 partitons.........HP_TOOLS have been deleted...
9.Now action time...........
10.Start Minitool Partition wizard.......it will diaplay your partitons.........select C: partition......right click on it .....select option move/resize...
11.New dialog box appears displays currents stats use the drag corners on top to reduce size for C: drive ......set the new size according to use..........But new size must not be less than 150 gb to avoid any data loss.....
12.leave rest of options intact.........click ok...........this will return you to minitool partiton wizrd home screen........click on apply at leftmost top corner..........it asks for permission say yes........then it displays that drive is in use you need to restart............
13.Click on Restart Computer........
14.Your Computer will restart in Mini tool partition boot mode dont press any key...........after loading it will start processing and shrinking............then copying data...........it will restart automatically after progress is done 100%..........be patient.........it takes upto 5-10 mins......
15.If every thing goes fine your computer will start normally.........then go to START> COMPUTER > RIGHT CLICK ON IT > MANAGE
16. New window opens, select disk management from it , given on left hand side....now you can see your C: partition has been reduced in size according to your size specified...........and unallocated space have been created along by C: partion.
17. Finally right click on unallocated space and select NEW SIMPLE VOLUME......a dialog box appers specify size to create a new logical partition...........you may create any number of logical drives till there is free space left...........
18.Now open My Computer ...........you can see your new custom partitions have been created........
19. Done.........enjoy.......
SUPPLEMENTARY:-
1. You can create any image creation tool......to create image of your C: Partiton and save image in yourcustom created partitons.......
2. In future if you want to recover system,,,,,you may use your created image using imaging software forrestoring your C: partiton......may be helpfull instead of running recovery.........
Drawbacks:
Running Recovery form DVD or recovery partiton may delete your custom created partitons...........all datamay be lost.....so regularly backup your data.....

After you delete HP_TOOLS partition, BEWARE about one thing: do you have something called HP support assistant in your laptop? if yes, beware when it wants to upgrade HP software, because it will make HP_TOOLS partition reappear without your permission!!

How to use Oracle partitioning with JPA @OneToOne reference?

Hi!
A little bit late in the project we have realized that we need to use Oracle partitioning both for performance and admin of the data. (Partitioning by range (month) and after a year we will move the oldest month of data to an archive db)
We have an object model with an main/root entity "Trans" with @OneToMany and @OneToOne relationships.
How do we use Oracle partitioning on the @OneToOne relationships?
(We'd rather not change the model as we already have millions of rows in the db.)
On the main entity "Trans" we use: partition by range (month) on a date column.
And on all @OneToMany we use: partition by reference (as they have a primary-foreign key relationship).
But for the @OneToOne key for the referenced object, the key is placed in the main/source object as the example below:
@Entity
public class Employee {
@Id
@Column(name="EMP_ID")
private long id;
@OneToOne(fetch=FetchType.LAZY)
@JoinColumn(name="ADDRESS_ID")
private Address address;
EMPLOYEE (table)
EMP_ID FIRSTNAME LASTNAME SALARY ADDRESS_ID
1 Bob Way 50000 6
2 Sarah Smith 60000 7
ADDRESS (table)
ADDRESS_ID STREET CITY PROVINCE COUNTRY P_CODE
6 17 Bank St Ottawa ON Canada K2H7Z5
7 22 Main St Toronto ON Canada L5H2D5
From the Oracle documentation: "Reference partitioning allows the partitioning of two tables related to one another by referential constraints. The partitioning key is resolved through an existing parent-child relationship, enforced by enabled and active primary key and foreign key constraints."
How can we use "partition by reference" on @OneToOne relationsships or are there other solutions?
Thanks for any advice.
/Mats

How to accelerate by partitioning drives & how to distribute data among 'em

Dear forum,
I have read guide to storage acceleration and guides to phototoshop acceleration, but they always warn that the best solution depends on the work i do, the hardware i have, and the hardware i think i can afford to buy. I'm hoping that if i tell you what photoshop work i do, what hardware i have, and what hardware i'm intending to buy, you can tell me how to accelerate by partitioning my drives and how to distribute data among them. My biggest questions are about how big the volumes should be, and what should go on each volume. It sounds vague here, but I get more specific below:
THE PHOTOSHOP WORK I DO:
*wet-mount raw scans of 6x7 cm film using silverfast software on microtek artixscan 120tf 4000dpi scanner: resulting 16-bit TIFF file is typically 550 MB in size.
*working in Photoshop CS2 on same file, adding multiple layers makes file 1 GB to 1.4 GB in size
*my system's limitations show up most painfully when I OPEN a file (this can take five minutes) SAVE a file (this can take more than ten minutes!), when i FLATTEN the image's layers for printing (this can take 5 minutes), and when i CONVERT the file from 16-bit to 8-bit (this can take 5 minutes). most other operations in Ps CS2 are fast enough (not snappy, but fast enough) for me to stay with my current processor for the time being.
THE HARDWARE I HAVE:
*Power Mac G5 dual 1.8GHz, made in 2004, with only 4 slots for RAM (not 8 slots).
(I'm told this has quite limited bus speed, as compared with other dual-processor G5s, and that this hardware will not benefit much at all from adding a RAID array.)
*one internal seagate 80GB 7200rpm SATA drive. this is half-full (it has 39 GB on it): it holds my OS and my Users folder, but NOT my photoshop image files.
*one internal Western DIgital 400 GB 7200rpm SATA drive. this holds my photoshop image files, but not my user folder.(This WD drive turns out to cause the G5 to hang up occasionally, requiring a re-boot; to avoid this, i recently learned, i can connect it with a host card adapter [see below].)
*two 500 GB external firewire drives
*two 300GB external USB drives
*I have 2.25 GB of RAM, but I'm about to buy 2 more GB to max out at 4GB.
THE HARDWARE I'M INTENDING TO BUY:
*2GB of RAM, of course.
*two Hitachi T7K500 500 GB SATAII HD 16MB Cache 7200rpm drives to occupy both internal drive slots in the G5
*a 2-drive external enclosure to hold my old seagate 80GB drive and my old WD400GB drive.
*a seritek host card adaptor for connecting the external enclosure to the G5.
THE PLAN:
What follows is a combination of suggestions I have received about what I could do and my speculation about how I could do it. Please see my Questions, embedded in the lines below: I'd be very grateful for any amendments or directions you can offer on this topic.
Drive A: first newly internal Hitachi 500GB drive:
partition into 2 volumes:
first (faster) volume, "volume A1," of 100GB to hold OS and Users folder but NOT photoshop image files.
(Question: how much space should I leave free on volume A1 for optimum performance? is 50% free of 100GB optimal? is 60% free of 100GB better? Is 50% free of 150GB better still? or does that cut into the other volume's space too much (indirectly cutting into the space of "volume B1" on Drive B, which is to be the WorkDisk/ScratchDisk)?
second (slower) volume, "volume A2" of remainder GB (almost 400GB) as backup for 400GB "volume B1" of the OTHER internal Hitachi Drive, a.k.a. Drive B.
Drive B: second newly internal Hitachi 500GB drive:
partition into 2 volumes:
first (faster) volume, "volume B1" of almost 400GB as designated WorkDisk/ScratchDisk for large photoshop image files;
second (slower) partition "volume B2" (exactly 100GB) as backup for 100GB volume 1 (OS volume) of the OTHER internal Hitachi Drive, a.k.a. Drive A.
(Question: how much space should I leave free on this WorkDisk/ScratchDisk for optimum performance? is 50% free of almost 400GB optimal? is 60% free of almost 400GB better? Is 50% free of 300GB just as good, with the additional advantage of indirectly allowing "volume A1" on Drive A to be 150+GB?
Drive C: old Seagate 80GB drive, in external enclosure: disk designated for running the Photoshop Application? How would I set this up? any pitfalls to watch out for? should i partition this drive, or leave the whole thing for Photoshop? or is it better to run photoshop off Drive D?
Drive D: old WD 400 GB Drive: second scratch disk? Storage disk? Both storage and scratch disk? how large should an empty volume on this disk be in order to be useful as a scratch disk? volume 1 or volume 2? if i run the Photoshop Application off of this drive, how large should the volume for that be? should it be volume 1, the faster, outside volume, leaving volume 2 for scratch disk space? or vice versa?
External Firewire and USB drives: i guess i'll just use them for storage/archiving and extra backup? or am i much safer buying more SATAs and Enclosures? or are the external firewire and USB drives plenty safe (so long as i double-back up), since i'll only power them up for the data transfer, and then power them back down?
Given that the large Photoshop files are not in my User folder, does it matter whether i keep the User folder (with its MS Word docs and a bunch of PDFs and so on) on my OS volume, "volume A1"? would it speed things up when I'm using photoshop if i moved the Users folder to another drive? what if i'd like to play iTunes while also working on photoshop? my iTunes music folder (with all the song data) is already on an external firewire drive. but the iTunes Library and iTunes application are, of course, in my User folder, which is on the OS drive. would moving the Users folder to another drive make much difference when i use photoshop and iTunes simultaneously?
But I wonder whether it makes sense to be using volume A2 on Drive A as a backup drive: wouldn't it make more sense to back up my working files to two external drives that can be traded out, one on-site and one off-site, back and forth (not so convenient when one of the backup drives is internal!)? and after all, why would i devote a 400GB volume to the task of backing up another 400GB volume that will never be more than half full? I need to leave a WorkDisk/ScratchDisk half empty for efficient use, but i can back up that 200GB of working files on a 200GB volume, right? so for a backup drive, I might as well use a slow, inexpensive external USB drive that will only be tuned on for backup and will then stay powered off, a drive that's easily transportable on and off site, right? or am i misunderstanding something?
by the way, what backup software do you recommend for backing up back and forth between Drive A and Drive B? I've been using Carbon Cpy Cloner. do you recommend that? or something that does more archiving of progressive states of data?
Thank you for any help you can offer!
Sincerely,

How to format boothcamp partition

I have iMac (Snow leopard OS) and a friend set up a partition and installed Windows but after years I realized I don't need it.
Is there anyway to format this partition so I can use it as another drive and can be browse from Mac OS?
This is my first Mac, I don't know how to manage the partition and I don't want to format the whole computer.
Thx

Use Boot Camp Assistant. Select the menu option to remove Windows and return the drive to a single OSX partition. Do not use Disk Utility, it will mes up your drive and you will need to reinstall OSX. Make a backup of your data before you start.

Why not look at how much you have free first? too many people end up redoing partitions because it is never "exactly perfect."
Also, if later you update to SP3 you need x amount of free space.

How to remove a partition of my hard drive

I have an old 2007 HP Pavilian DV6000 series with Windows Vista. At some point, one of my husbands friends had the bright idea to partition the hard drive and put Linux (Ubuntu) operating system on my laptop. I haven't used this laptop in a few years now because once he did that the laptop has been screwy ever since. I want to remove that OS and remove that partition. I don't have a recovery disc to do a factory reset, I've tried that and I've tried restoring to early point and nothing is working. So how can I un partition that part of the hard drive and remove that horrible OS?? Vista is still on there and I can still access Windows, but I just want my computer back to how it should be. Thanks!

How to create recovery partition in new(changed) HDD.

my new HP pavilion g4 laptop HDD have crased, then I replce it by HP care. I upload original win 7 by recovery disk(DVD) but when I open my computer it shows only one partition (C drive, there is no recovery partition and HP tool.
So how to creates recovery partition by recovery disk(DVD)...........please help me.

Creating the recovery partition
Right-click the start orb, and start 'Disk Management'.
Shrink the C: drive by let's say 20-30GB.
Then create a new Partition and assign the R: label to it and name it RECOVERY.
Then open command prompt as administrator and type: 'recimg /createimage <directory>',
In this case: 'recimg /createimage R:\' to save it on the new partition.
This step may consume a lot of time.
Now we need to register the newly created recovery image: 'recimg /setcurrent <directory>'
'recimg /setcurrent R:\'
Voila you are done.
Restoring from recovery partition
You may want to use this restoring method by default, because it is the easiest way to do so if your recovery partition is still intact. If not, look at the other recovery methods to see which suits you best. This is usually the way you reset or refresh your Windows installation if you purchase a computer from a brand like Lenovo instead of building one yourself
Press the Windows-key + C to open the charms bar or swipe in from the right.
Click Settings.
Click Change PC Settings.
Click Update & Recovery in the menu on the left.
Click Recovery.
If all your documents are safe and sound in your user folder, you can use Refresh your PC without affecting files. However I still recommend taking a back-up... If you want to do a complete reinstallation of Windows and also clean your user folder in the process then choose Remove everything and reinstall Windows.
