Boot up from other node's boot disk
Hi,at the moment I got problem to boot up one of two nodes-cluster, because its boot disk seems to be damaged. Is it possible to boot up from other node's boot disk? If yes,how to do it? If not,are there any ideas,beside replacing the damaged boot disk? Because the machines are in testbed, I think my compay doesn't want spend much money to replace the disk in this short time =)
The version is SOLARIS 8 and SUN Cluster 3.0.
Hi,
Sorry to disappoint you but you cannot in Sun Cluster have one node boot from the boot disk of the other node. Do you have a backup of the boot disk?
Your best option is to replace it I guess

Trying to boot arch from win7 with EasyBCD; "boot device not found"
EDIT: title was 'Dual boot with Win7, easybcd + syslinux, getting "Boot error"'. Narrowed down the issue to something unrelated to Arch, and felt this was more accurate. The Arch install is sound, it's getting win7/EasyBCD to load it that's the issue.
I got a new work computer and am trying to recreate my formerly successful setup, which I documented here some time ago. Unfortunately... I'm having issues. Just a note up front from scouring the internet for ideas: I cannot use syslinux (or any other bootloader) to chainload Win7 vs. the other way around! The computer drive is encrypted with McAfee Endpoint Encryption, and doing anything whatsoever with the MBR from outside of Windows will brick my computer. Just wanted to add that, as almost all issues involving dual boot inevitably bring about the suggestion to "just chainload windows from grub/syslinux/etc."
With that out of the way, here's the process I used:
drive setup
Here's the partition scheme:
- /dev/sda1: SYSTEM (pre-existing)
- /dev/sda2: C:, Win7 (pre-existing)
- /dev/sda3: /boot, ext2 (created)
- /dev/sda4: /, encrypted Arch root, cryptsetup/ext4 (created)
My process for creating the partitions is as follows:
- shrunk C: down from the Win7 built-in partition utility
- created two unformatted partitions with no drive letter using Minitool Partition Wizard, setting the partition ID to 0x83 for both
- booted from USB drive of the Arch installation .iso (downloaded Friday 5/29)
- booted x86_64 arch

I just followed the Arch installation guide but documented my steps to a text file just to be sure...
# mount /dev/mapper/root /mnt
# mkdir /mnt/boot
# mount /dev/sda3 /mnt/boot
### connect to internet
# pacstrap /mnt base
# genfstab -p /mnt >> /mnt/etc/fstab
# arch-chroot /mnt
# echo arch_zbook > /etc/hostname
# ln -sf /usr/share/zoneinfo/America/Chicago /etc/localtime
### uncomment en_US.utf-8 in /etc/locale.gen
# locale-gen
# echo LANG=en_US.UTF-8 > /etc/locale.conf
### add encrypt before "filesystem" in /etc/mkinitcpio.conf hooks
# mkinitcpio -p linux
# passwd
# pacman -S syslinux
# cp -r /usr/lib/syslinux/bios/*.c32 /boot/syslinux
# extlinux -i /boot
### the above echoes "/boot is device /dev/sda3"
Then I edited /boot/syslinux/syslinux.cfg:
LABEL arch
MENU LABEL Arch Linux
LINUX ../vmlinuz-linux
APPEND root=/dev/mapper/root cryptdevice=/dev/sda4:root crypto=sha512:aes-xts-plain64:512:: rw
INITRD ../initramfs-linux.img
EDIT: I deleted the contents of /boot, reinstalled syslinux, linux, and mkinitcpio, and repeated the above with `extlinux -i /boot/syslinux`, noting that syslinux.cfg points to ../vmlinuz-linux. Same result.
Just to double check proper syslinux setup, here's the dir contents:

EasyBCD and boot attempt
At this point, exited the arch-chroot, unmounted/closed my partitions, and rebooted into Win7. Using EasyBCD, I added a entry for a syslinux bootloader, pointing it to "Partition 3 (Linux - 128MiB)."
I reboot, get the EasyBCD menu, but then the lone words "Boot error" on a black screen. Any key press takes me to some sort of BIOS boot thingy which tells me to "Please install an operating system!" I think this is something built into the laptop BIOS, not anything from the syslinux side. Selecting "Boot existing OS" from the Arch install USB doesn't give me any options at all.
From what I can tell, I'm using the same procedure that I ended up with on this former troubleshooting exercise.
Thoughts
I'm really struggling to understand what I'm doing wrong. I originally had a couple variations on logical/extended partitions since I need my eventual setup to hold a shared TrueCrypt partition so I can access my work files from both Win7 and arch. I tried /boot as primary and Arch/TC as logicals, as well as a primary TC partition with boot/root as a logical drive combination. I've simplified to just primary partitions (as shown above) to troubleshoot.
It's quite difficult to troubleshoot as I don't know if this is an installation issue or an EasyBCD one. Is there a way to manually try and boot my HD arch install from the install USB? I wanted to try that using the "Boot existing OS" option, but am wondering if it fails since only /dev/sda1 features a bootable flag and it's encrypted so only the HP BIOS can handle it? I thought about making /dev/sda3 bootable, but from my reading I can only have one bootable flag on a Windows system.
On that note, I checked my BIOS settings and the MBR is set to "Legacy mode" vs. the othe UEFI alternatives, so I don't think that's an issue. I also used blkid to confirm that it's using an MBR (output was "dos").
I will try UUIDs in /etc/fstab and syslinux next, as there are some other posts (example) talking about this as a potential issue (and, indeed, I sometimes get my HD as /dev/sdb* when booting from the arch USB drive. I can also try grub2 in case it's a syslinux issue.
Thanks for any ideas/suggestions. Does anything look awry in my description/setup above? I can chroot and do stuff just fine... so I think the install appears to be sound; it's just booting it!
Last edited by jwhendy (2015-06-06 04:38:09)A bit of progress, though this couldn't be much more awful in my opinion. Installed Arch to an sdcard to use as a bootloader, only to find that I can't boot from an sdcard, even though the HP docs say there's an sdcard boot option in the BIOS (which there's not). If the BIOS were in UEFI mode, there is an sdcard option listed in the boot order, but not in legacy mode. Sigh.
I don't have another sdcard laying around that's big enough to install Arch on, as I'm using my sole 8g drive for the installation media (and no optical drive). Sigh.
I did, however, through trial and error get my sdd arch install to boot using the installation drive's "boot existing OS" option! Took me a while to figure it out. In my opinion the drive/partition numbering is quite odd. Using the Hardware Information tool, the usb stick shows up as the first drive (so I'd assume hd0), but it can't be as "hd0 3" got me into the sdd installation. I'd have assumed hd0 0 was /dev/sda1, but that must be incorrect, as hd0 3 is /dev/sda3.
So, where I'm at now:
- going to re-partition how I originally intended (with truecrypt shared storage as a primary partition and boot/root as logical partitions)
- reinstall arch
- try to boot using the above procedure from the installation media
If that goes well, I'll try to find some teensy tiny usb stick to use as a bootloader device unless someone has any insights on why I can't boot by chainloading from Windows. I think at this point I've narrowed it down to a BIOS or drive numbering or EasyBCD issue, so maybe this post isn't a good fit for the Arch forums after all. Sorry for all the noise/updates... just wanted to provide the updated information as I uncovered it.
Thanks if you have any ideas or things I could try. -
Problems looking up JMS queues in JNDI from other nodes
I have a simple cluster(MyCluster) in weblogic 6.1 which consists of two managed servers
(Server1 & Server2).
Server1 has a JMSServer (JMSServer1) containing a couple of JMS queues.
I also created a JMS Connection Factory, and targeted both the managed servers as
well as the cluster.
I can look up the queue from the node hosting the JMSServer, but cannot look up the
queues from the 2nd node (server2).
It just says that it cannot resolve the jndi name for the queue on Server2.
According to weblogic docs, I should have transparent access to the queues from server2
as long as i target both servers from the connection factory.
Am I missing something?
Thanks.

Booting MBP from SATA external drive/hard disk
I have an external SATA HD 120GB portioned in to 4 partitions. It is in an ICY BOX SATA house. Connected direct to the MBP via an USB cable. No external power supply.
I have cloned the OS from the MBP to one partition on the external disk (using SuperDuper!).
I can see the external device in the System preference window ‘Start-up Disk’ I can select it, but it refuses to start up from it. When I do a restart it starts up from my internal HD.
If I hold down the Alt key at start-up I do not see the external HD.
I also have an other non SATA disks connected via FireWire with a cloned version of my OS and here I have no problems.
Any suggestions as to how to be able to boot form the external SATA disk?
ThnaksIn Disk Utility/Partition/Options we can read:
- GUID Partition Table (GPT) "to use the disk to start up an Intel-based Mac".
- Apple partition Map (APM) "to use the disk to start up a PowerPC-based Mac or to use the disk as non startup disk with any Mac".
At http://developer.apple.com/technotes/tn2006/tn2166.html we have very important secrets of the GPT:
- Any Mac running Mac OS X 10.4 and later can mount GPT-partitioned disks.
_ Intel Macs can boot from GPT. By default, the internal hard disk is formatted as GPT.
- While Intel Macs can boot from GPT and APM, Apple only supports booting Mac OS X on these machines from GPT. Apple's GUI tools, like the Installer, will prevent you installing Mac OS X for an Intel-based Mac on non-GPT disks.
Many posts In this forum telling ius that it is mandatory to format disks GUID partitioned to boot MBP.
But, in other forums there are some opinions about APM too:

. http://www.micromat.com/index.php?option=com_simpleboard&Itemid=42&func=view&cat id=7&id=786
We are discuss the boot capability of external drives and I wish someone can clarify this question to isolate software (include cloning software) or hardware problems.

Prevent VIP's from other nodes to start on 11gr2 RAC ??
I have one node which is part of 3 node 11gr2 RAC.
Other 2 nodes(rac1, rac2) a power down, and on this node(rac3), crs is down.
Problem is, that, if I switch crs up, he will up all VIP addresses , from
rac3-vip, but, also rac2-vip, rac1-vip..but, this (rac1-vip, rac2-vip) is
already VIP address's in production on second RAC.
1)Can I somehow disable this 2 VIP's BEFORE I start crs on rac3 to prevent
this other VIP address to start on rac3???
2) If no, can I start crs, and quick stop down this VIP's,
crs_stop ora.rac2.vip
crs_stop ora.rac3.vip
3) and maybe somehow prevent from future start before I really migrate
everything on new RAC??

Today the VIP hostnames resolve to the 10g RAC's VIPs. Tomorrow when the switchover to 11g happens, the DNS is updated and these VIP hostnames resolve to the 11g RAC's VIPs.
So, I want on this third node from 11gr2 RAC to stop those VIP's, which is the same as prod VIP's..so I can have third node up, and first 2 node from 11gr2 rac down (which have same VIP's as 10g rac)Just the idea of purposefully creating duplicate IPs on a network.. Crazy...
You can try and hide those 11g RAC duplicate IPs from the network. Routing table is perhaps an option. Using iptables is another Or as you want, preventing the VIPs from starting in the first place.
But you should take this as a lesson in how NOT to configure networking. Duplicating IPs is simply a no-no. There is no reason I've ever seen, nor can think of, why IPs should be duplicated like this. Hostnames resolution exists for addressing such requirements. -

Hi Shipon,
Your network configuration not meet the cluster network requirement,
Network adapters and cable (for network communication): The network hardware, like other components in the failover cluster solution, must be marked as "Certified for Windows
Server 2008 R2." If you use iSCSI, your network adapters should be dedicated to either network communication or iSCSI, not both.
In the network infrastructure that connects your cluster nodes, avoid having single points of failure. There are multiple ways of accomplishing this. You
can connect your cluster nodes by multiple, distinct networks. Alternatively, you can connect your cluster nodes with one network that is constructed with teamed network adapters, redundant switches, redundant routers, or similar hardware that removes single
points of failure.

How to Restrict same portal user from other node
Hi
In my application, we charge customers for each portal user logins. But, i found that, they can share same user logins amongs number of people.
I don't want to allow the same portal user login into the application if that user is already logged in and it's session is still active.
Here is the Scenario :
User A is logged in to the portal from terminal AA. Now, User A agin tries to logg in to the portal from terminal BB. I don't wnat to allow user A to log in from terminal BB bcuz user A has active session from terminal AA.
Can anyone know how to implement this??
thanks in advance.
SriniHi Srini!
We have solved this problem with our own login portlet. Before the final login we've got to check (from the certain table) how many logins there are currently with that username.
But there is a problem. If the user closes the browser without logoff, the session remains active. There is a cleanup job, which removes those session in some hours. Still it is not very elegant.

Can't read disk label: Booting Blade from CDROM
Folks !
I am trying to boot Sun Blade 100 from its internal IDE CD-ROM drive
using the Solaris 8 boot/installation CD (01/01). When I give the command
"boot cdrom" from ok fromt in OpenBoot, disk seems to spin for a moment
(green light comes on) but it eventually fails complaining:
can't read disk label
can'open disk label package
failed to open boot device.
I have tried following (all to no avail)
"boot /pci@1f,0/ide@d/cdrom@1,0:f" since devalias shows that cdrom is aliased to above. I also tried cdrom@0,0:f, but same result.
tried boot/installation CD from Solaris 9
did set-defaults reset-all
checked probe-ide and show disks output to make sure CDROM is recognized - it is primary slave.
swapped another IDE CD-ROM drived pulled from a PC. It was recognized but still not bootable.
Makes me wonder if PROM/NVRAM is corrupted. Hard disk
drive is trashed as such (another Blade 100 problem, since it was crashing
often, I had to force powerdown using the switch eventually leading
to corruption of basic files like /usr/lib/libnsl.so.1, so I can't force fsck)
I have to boot from CD to recover the machine and hopefully
repair the disk drive or swap it out and upgrade to Solaris 9.
any help would be appreciated.
thanks very much.
-Sanjay Kumaras per the message it appears either you have a bad CD drive or CD media . If you have another machine try to boot this CD and verify it is working there. If the CD is ok you will have to swap the cd drive for testing

From yesterday onwards, from one instance accessing data from a specific data file showing the below error, whereas accessing from other node to the same datafile is working properly.That would be due to some kind of failure in the shared storage layer.
RAC needs the very same storage layer to be visible and available on each RAC node - thus this needs to be some form of shared cluster storage.
Should a piece of it fails on one node, that node would not be able to access the RAC database files on that shared storage layer - and will throw the type of errors you are seeing.
So how does this shared storage layer look like? Fibre channels (HBAs) connected to a Fibre Channel Switch and SAN - making SAN LUNs available as shared storage devices?
Typically a shared storage failure would throw errors in the kernel log. This is because the error is not an Oracle error, but a kernel error. As it is in your case. The bottom error on the error stack points to the root cause:
ORA-01157: cannot identify/lock data file 75 - see DBWR trace file
ORA-01110: data file 75: '/dev/vg_rac/rraw_tap3plus_temp_live05'
ORA-27041: unable to open file
HPUX-ia64 Error: 19: No such device
So HP-UX on that node is not seeing a specific shared storage device. -
Want to boot XP from an external disk? Here's how:
Has to be a USB 2.0 drive:
http://forum.onmac.net/showthread.php?t=1015
By: gradenko
Source: www.onmac.net
[edit: you have to keep the 5GB NTFS parition on your internal drive for this to work]
Hello, I cannot find a working solution for this posted so I'll post the solution I came up with (well, cobbled together from other people's hard work). I am using a MacBook Pro and an external G-Tech Q drive that supports USB 2.0. While XP does not officially support booting from a USB drive there is a way around it.
This solution requires access to a PC and is a bit time-consuming.
1. Use BootCamp to create a 5GB XP partition.
2. Using a PC and your Windows XP SP2 CD, go through the following process to create a USB enabled XP SP2 installation CD: http://www.ngine.de/index.jsp?pageid=4176
3. Plug your USB 2.0 external drive into your mac.
4. Put your new XP SP2 CD into your MAC and boot holding down the "C" key.
5. XP installation should begin, when you get to the drive choice, be sure to choose your USB drive. You may have to pre-format this drive to NTFS, mine was already formatted.
6. You will get a screen warning you that drive C needs to be formatted. This is OK because XP needs to write some temporary data to the startup (internal) disk. It will format the 5GB XP partition you created in step 1.
7. Follow the installation prompts and when your Mac reboots be sure to hold down the Option key. You will get a choice to boot to either your OSX installation, XP or the XP CD. Choose the XP hard drive.
8. The normal XP installation will continue. You will get some warnings about unsigned divers. This is fine and is occurring because you tampered with the XP installation files in step 2. NOTE: My installation hung once here. I just reboot and tried from step 7 again and it worked fine.
9. Once XP comes up install your BootCamp device drivers.
Good luck! I just now finished this so I have some testing to do. A very big thank you to emmanual from ngine.Hi,
without the preperations to be made, that are outlined in the link I gave, Windows always tries to read and write certain files during bootup, which it can't find when you 'only' have a Windows on an external HD.
I only know of these instructions to get Windows on external HDs to work.
If it weren't for games you like to play, I would suggest to have a look at the 'Virtualization' apps like Parallels or VMWare Fusion.
But these aren't good for playing games.
Sorry

Is it possible to boot from a shared dvd or disk image remotely
Is it possible to boot from a shared dvd or disk image remotely without using netboot for install or utility?
All Apple Remote Desktop can do is point a system to a startup disk; it has no facility for providing a boot image. So you may want to ask this question in the Mac OS X or Mac OS X Server forums. You'll be more likely to get suggestions there, though other than NetBoot I know of no way to boot a group of computers from a single disk image or DVD.

2005 mac mini on OSX leopard will not boot up from firewire disk
I have an old mac mini that my son still uses and the super dirve does not work any more. But now the main hard disk needs to some attention from Disk Utility. So I need to boot up from the Leopard install DVD. But of course the DVD dirve does not work so how to do this? I have tried to create a bootable disk by restoring the install DVD to a partition on a firewire drive and this is seen as a bootable drive by my 2008 iMac, but not by the Mac Mini. So is it possible to boot up rom a irewire drive? USB doesn't work either
Which Tiger Install DVD do you have...?
1. I think that, that model originally came with 10.4.10 and so you will need either the original 10.4.10 install disc or a later retail (Leopard or Snow Leopard) upgrade DVD.
2. In addition, a new (HDD, Hybrid Drive or SSD) must first be Partitioned GUID Partition Table and Formatted Mac OS Extended (Journaled) before OS X can be installed. -

I just bought a 250Gb Lacie D2 triple interface external hard drive to go with my 15" 1.25ghz G4 powerbook.
I partitioned the External drive into two volumes, one of which I will reserve exclusively for backing up my entire Powerbook hard drive.
I used the software (Silverkeeper) that came with the Lacie disk to copy the powerbook hard drive onto the Lacie disk. When I commenced the copying, a dialog box asked me if I wanted to make the copy 'bootable' I clicked yes.
Now for my question..... How do I boot up from the copy???
I had assumed that if I switched off the powerbook & then re-started it, (with the Lacie disk connected... Firewire 800) that I would then be given the option of booting from either the Powerbook hard drive OR the Lacie hard drive. Not so.... Powerbook booted up as per normal, having 'recognised' the Lacie disk & placed it's icons on my desktop.
Obviously there is a simple step I am unaware of, probably holding down a combination of keys whilst re-booting???
So....How do I boot up from the copy?
regards
Ian

If you are updating the OS on it you might want it to persist through reboots vs using the very time consuming Option key method each time.
To go back to the original boot disk or any other one just go to preferences and select the one you want again. Much faster. -
How to boot always from a firewire disk?
Hello,
I hope someone can help me on this.
My HD is almost dead and it's making a lot of noise. I have managed to create a boot disk
on an external disk connected through Firewire.
What shall I do now to have the HD definetly unmounted and have the boot always from the firewire disk?
Thanks in advance
TomI've had a similar problem with an external drive that was USB powered.
In my case, the system was looking for a boot device before the drive was ready.
I had a friend that was good with OpenFirmware add a delay before booting to give the drive time to become ready. Added 5 seconds to the boot process, but it works!
Like cldjr said, hold the Option key (⌘) when powering up, if the drive shows up there, I'd guess it's the problem I described...
Anyone good with OpenFirmware??
