Virtual disk failover - help required
Hi to all,
How to manage guest domains ?, if primary domain is offline and alternate domain is online.
When i tried installing ldom software on alternate domain, it got installed but ldmd daemon and smf not enabled.
Can anyone answer ?
Thanks in advance..

Virtual Disk Failover/Multipathing question
In the LDOM 1.1 Admin guide the section on virtual disk multipathing leaves me with one question.
LDOM 1.1
Scenario: T5240 with 2 IO domains. Each IO domain has an HBA attached to shared SAN storage. The storage folks assign you the same 2 luns to both HBA's. Does each LUN have to be a member of it's own mpgroup? Or can all 4 luns belong to the same mpgroup?
Put another way which is correct A or B?
(Assuming the SAN disks are c1t0d1 c1t1d1 refer to the same two LUNS on both IO domains.)
A:
ldm add-vdsdev mpgroup=guestdom1 /dev/dsk/c1t0d1 vol0@primary-vds0
ldm add-vdsdev mpgroup=guestdom1 /dev/dsk/c1t0d1 vol0@primary-vds0

this is the only forum entry to ldoms and the mpgroup option,
so i hope to get the answer to my problem here.

Adobe Audition R6025 Virtual C++ Crash (Help Required, Please!)
Hi. I posted a problem about Rewire earlier but I seem to have sort of overcome that. My problem now is that I get a crash with a dialogue box stating that AA is shutting down:
'To continue working where you left off, please restart Audition.'
This is followed by another dialogue:
'Microsoft Visual C++ Runtime Library Runtime Error! R6025 - pure virtual function call'
And then it shuts down.
I searched for solutions and have discovered that r6025 is a very general fault that can mean a number of things. Here's the specific thing that causes the crash:
If I have a session from me previous machine open, it'll play fine. If I try to change the input to a track, that's when the crash occurs. I can do it if I create a new session (I think - I haven't done anything complicated from scratch since I got a new PC this week).
I have tried a few things that have been suggested on other posts:
Reinstalling AA (a few times).
Running Audition in compatibility mode for XP SP2, XP SP3 and not in any compatibility mode.
Uninstalling Quicktime (as suggested http://forums.adobe.com/thread/414943).
Deleting the Application Data backup so that a new one gets created next time (as suggested http://kb2.adobe.com/cps/403/kb403357.html).
Disabling all plugins.
Trying it out on another User ID.
None of these measures have helped as of yet. I'd really appreciate some help or some suggestions of actions I could take. My system is an AMD Phenom II X4 945 (AM3) in a Gigabyte mainboard with 4GB RAM, running Windows 7 Professional 64-bit, AA 3.0.1 and using my Audigy 4 Pro from my old PC rather than the onboard Realtek HD Audio (for Asio purposes).
Please post if you need any more details to help with diagnosis.
Anticipated thanks.Hi. Thanks very much for the posts. I'm aware of the 48kHz issue from previous incompatibilities with other people's sessions. Always managed to work in 48kHz with Reason before using XP. I've just tried the ASIO4ALL driver with the same result, I'm afraid. Not really sure if the problem is limited to Reason because I don't own any other Rewire apps. I'm really hoping to get this sorted out because I use Reason an awful lot in conjunction with Audition as I think they make a nice pairing of complimentary skills (lack of a tempo track notwithstanding). I can change inputs on sessions with no Rewire tracks in them, using either Creative Asio or ASIO4ALL and it doesn't crash. I can also use Reason quite happily on it's own. I've even managed to create a new session with a couple of wav's and then set Reason on another track with no problems (although these sessions are very simple). I'm really stumped. I suppose I could try to run the whole thing in XP Mode but that negates some of the advantages of using my new computer and requires me to install everything, Audition, Reason and all my plugins, for a second time. I will do that if I have to but that's what my Dad, a scientist, would call an inelegant solution. Again, I really appreciate the suggestions you've come up with thus far. The ASIO4ALL idea was a good one and I'll keep it installed too as an option for when other problems (inevitably) arise. I'm loath to discard what was a reasonably expensive sound card (even if it is a bit dated and patently not designed for audio engineering). In my old set up, I used the Audigy for mixing and monitoring but my MBox as in input due to it's Focusrite preamps. Don't get me started on my MBox and Pro Tools!!! Haven't even started to install that yet because I know it'll be a nightmare. It's hard enough trying to install an update from Digidesign. I'd really be much happier to get things back to the way they were - plus a much faster processor and more RAM. That was the whole idea of the new machine. I really love AA and have done since Cool Edit 1.2. I'm too set in my ways to try and learn new software, not too mention too poor to buy any!! Any ideas really gratefully accepted.

Help needed to recover corrupt virtual disk - No snapshots
Hi
Please could somebody help me.
I was running Clean Up Virtual Machine and then I Force Quit Fusion. Now I can't start my VM. I have run vmware_vdiskmanager to try and recover the virtual disk, but I get the following error.
VixDiskLib: Invalid configuration file parameter. Failed to read configuration file.
The virtual disk, '/Users/juan-emil/Documents/Virtual Machines.localized/Windows 7.vmwarevm/Virtual Disk.vmdk', is corrupted and cannot be repaired.
In an attempt to solve the problem I created snapshots to see if I can recover from them, but all I did was to un-associate my fusion with the virtual disk.
What do I do. Please somebody help. I cannot afford to loss this VM. All my work is on it.If even vmware-vdiskmanager cannot repair the .vmdk file anymore, then I'm afraid that you may need to revert to your latest backup. What may be worth a try though is to see whether another start of the clean process will work!?
Other than the above, you can try to contact continuum, who may have further ideas.

Virtual Disk copy - abort- still copying - HELP
I started a virtual disk copy from one repository to another.
This particular disk is 2 terabytes, so very sizeable.
I decided about 200 Gigs through to stop and do something else so I clicked Abort in the Jobs.
I then check the jobs and yes it has a finish time of 235pm yesterday afternoon.
Today I check my repository and the file is still building. Like the file copy did not stop even though the job is confirmed that it was aborted.
I really don't want it to place this 2Gb file on my repository.
Its about 550Gigs through now.
Any ideas on how to stop this thing?I suspect the job has been aborted, so that no further tasks will be run. However, the in-progress copy is not aborted. This is possibly a bug, but I suspect it's not because we don't abort in-flight processes when you hit that button. Just the job itself. You could just kill the copy process yourself now that the job has been aborted.

Recently, our mail server crashed at about 7pm one night, with the error 'There is no more space for virtual disk ServerName_2.vmdk. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.'
When we click Retry, the server starts up OK.
There are no snapshots listed in Snapshot manager for any of the virtual machines on the host.
There is also free disk space available on the host and for the VM with the disk errors.
This happened at least three more times, often at bad times. Each time, we were able to click 'Retry' and the disk/system would allow the VM to start-up successfully.
I checked the Forums, the VMware support articles and the internet as I had not seen this problem before. I have completed the VSphere 5.1 - Fast Track course and this issue was NOT covered in the training.
Most of the advice on-line and even that on the VMware web-site was pointing to snapshots being the cause of this issue. There are no snapshots enabled and I cannot see evidence of snapshots ever being used.
- We are running VMware vsphere (5.1.0) and there are (were) 4 virtual machines running on the ESX host. We are using the free version of VMware/ESXi.
- The Hard disk types we are using for this Virtual Machine are 'Thin Provisioned'.
- There are 4 [Thin Provisioned] Hard Disks for this virtual machine.
- There are 6 CPUs
- There is 20GB of RAM (memory)
- The VM is running Windows Server 2008 R2 as the guest/VM operating system. It is an Exchange 2010 SP1 mail server. There is plenty of available disk space on all the drives. The [Exchange] log files are cleaned out regularly (automated).
I decided to move one of our non-critical servers off this host and on to another host to see if this helped the problem. This took quite some time, as we are not using HA or vmotion, nor do we have VCenter Server...nonetheless, I finally managed to get the non-critical server on to another host (n.b. This was a much smaller machine with less virtual resources assigned to it).
After moving the non-critical server off this host, we decided to monitor the Host and see if the issue resolved itself.
I checked the host about 6-10 times a day, from first thing in the morning till last thing at night - monitoring the performance of not only the Virtual Machine, but the ESXi host also.
There were no adverse performance issues. The only thing I did note, was in the Summary page on the ESX Host, under Storage, was If I right-clicked on the datastore and clicked refresh, then the free disk space would drop (ie from 140GB to 125GB).
After monitoring the host and VM for about 2 weeks, we did NOT have another instance of the above error.
Sorry for the long winded post, but I wanted to give as much detail given this error has been raised before and snapshots are usually blamed as the cause.
My question is this:
If the ESX host had plenty of available disk capacity and there were no snapshots enabled on the VM (or any other VM's on the same host), then why did our Virtual machine crash with the error that 'there is not more space for virtual disk Servername_2.vmdk'?
How do we prevent this issue from happening if we don't know the underlying cause?
I would greatly appreciate any advice or suggestions.
If I have not provided enough info on the specs or environment, please let me know and I will provide more information.
Thanks all,
KurtThe type of storage is really based on your requirements, and your ability to withstand downtime.
iSCSI as you are using with a NAS such as Synology or QNAP. NAS Selector - Support - Synology - Network Attached Storage (NAS)
I wouldn't use iSCSI for Exchange or any database. It's a bit slow.
Do you have a single physical host? Then I'd probably to an external direct attached storage. This would be a card inserted in your host server that gives you multilane SAS/SATA connectivity (www.techcable.com/SAS-SATA/SAS-SATA.pps) and an external disk enclosure/array.
For multiple hosts to a single array, I recommend a fibre channel connection to a FC capable switch, and on to a FC connected array.
We used to use a HP P2000 (on old G1), but it's since been retired. Worked pretty well once firmware was upgraded. http://www8.hp.com/us/en/products/disk-storage/product-detail.html?oid=4118559#!tab=features. They can be connected via iSCSI, Fibre Channel or 6GB SAS so they are flexible and reasonably priced.
Recommendations:
Use RAID 6 with your large disk arrays. With large disks there is a measurable failure rate when rebuilding a failed RAID5 array based on MTBF.
Use smaller 15K disks in RAID 0+1 for speed on databases/Exchange.
Use slower 7.2K disks in RAID6 for file storage.
We are a small hospital and we have 3 VMware servers with dual CNA (FC and Ethernet in a single twinax cable) connections to 2 redundant Cisco Nexus 5K switches and then 4 Fibre Channel connections to an EMC VNX 5300. It's extremely fast with about 50 virtual servers, but was quite an investment. One thing we don't have to worry about is down time. If there ever is an equipment failure, we have redundant everything, including power split between two UPSs.
Our VNX has 3 tiers of performance. 3 100GB SSD "Fast Cache" in RAID 1 with hot spare, to keep the most used data ready, but it's not really a tier, however one could be built utilizing the same disks. A second tier is performance tier with a 8 600GB RAID 0+1 and hot spare. The third is a bunch of 7.2K 3TB disks in RAID6. The VNX autotiers, placing data on disks depending on where it's needed. The volumes are sliced and diced automatically in the background to make this happen and we never have to touch it. I used a demo of Solarwinds Storage Manager to monitor performance for a while and the utilization was always low, meaning all data access was fast, througout the day.

Hi, I'm having a problem in a VM Guest cluster using Windows Server 2012 R2 and virtual disk sharing enabled.
It's a SQL 2012 cluster, which has around 10 vhdx disks shared this way. all the VHDX files are inside LUNs on a SAN. These LUNs are presented to all clustered members of the Windows Server 2012 R2 Hyper-V cluster, via Cluster Shared Volumes.
Yesterday happened a very strange problem, both the Quorum Disk and the DTC disks got the information completetly erased. The vhdx disks themselves where there, but the info inside was gone.
The SQL admin had to recreated both disks, but now we don't know if this issue was related to the virtualization platform or another event inside the cluster itself.
Right now I'm seen this errors on one of the VM Guest:

We don't know if this can happen again, what if this happens on disk with data?! We don't know if this is related to the virtual disk sharing technology or anything related to virtualization, but I'm asking here to find out if it is a possibility.
Any ideas are appreciated.
Thanks.

Unable to repair degraded Virtual disks in Storage Spaces 2012R2
Hi all,
I have an anoying problem that I cannot seems to find a solution for.
I have a 2 node Failover Cluster with CSV-volumes consisting of 2 HP DL360 servers with 2 LSI 9300-16e HBAs each, connected to 3 Supermicro JBOD-cases with a total of 84 disks. With Storage spaces I have made 1 Pool with 6 virtual disks and 3 of these disks
are Degraded. However, when I look at the physical disks they are all fine and healthy, if I try to repair the disks it finishes without any error messages but the disk is still Degraded.
OS = Windows Server 2012R2
Anyone have an idea?

This may be a dumb question, but I can't seem to find any definitive information after having done many, many searches. Short question is - can Windows Server Backup spread a single backup job across multiple disks if they are not in a storage
pool or some other RAID/JBOD structure?
Background:
I'm running Server 2012 Essentials with all Windows Updates installed. I have been backing up approx 2.8TB of data (Bare Metal Recovery, C:, S: (shared folders), and system reserved) for the past year+ onto a storage pool made up of two-2TB external
USB drives. Backup is slow (takes approx 1.5 days to complete), but generally works. Not surprisingly I was constantly getting capacity low messages so I decided to increase my backup storage pool by adding a 3TB drive and another spare 750GB drive
for a total of 7.75TB. Instead of having four separate external USB enclosures, I bot a 4-bay enclosure - Startech.com model #S3540BU33E to simplify this (or so I thought!).
The first problem I had was adding the two new drives to the existing storage pool. I think that is because the Startech uses a JMicron USB controller that reports identical uniqueid's for all drives so only one shows up in the GUI interface for creating storage
pools. After doing research on this, I set up a new storage pool and virtual disk using all four drives via Powershell and thought I was good. However, when the backup ran, it failed after filling the first drive, saying there was no remaining capacity. In
reality there were three remaining empty drives and there storage pool reported almost 5TB of avail capacity. I assumed this was due to the identical uniqueid issue so I decided to try a different tactic.
Instead of using a storage pool that combines all four disks into one virtual disk, I just added each of them to Windows Server Backup as individual drives thinking it would manage them collectively. I.e., when a drive filled up during a particular backup,
it would just start using the next drive and so on. Apparently this was a foolish assumption because the backup failed again as soon as the first disk filled up.
So now I don't know if this is still an issue with the identical uniqueid's or if Server Backup actually can't spread a single backup across multiple individual drives that aren't in a pool or other virtual disk implementation. Hence, my original question.
My guess is that it does *not* spread them across individual disks, but I just wanted to get confirmation.
ThanksMandy,
Thank you for following up on my question.
Unfortunately the article you referenced doesn't address what I am trying to accomplish.
The article focuses on saving the same backup job to multiple disks and rotating the disks between on and offsite for enhanced protection. However, it still requires that an individual backup job fits on a single disk.
What I am trying to determine is if a single backup job can span across more than one physical disk (during the backup process) without those physical disks being in some type of virtual disk implementation (e.g., storage pool, RAID, etc.).
Thanks,

Oracle VM 2.2: why virtual disk must be 1GB or larger?
I'm using Oracle VM 2.2. When I try to create a virtual disk using OVM Manager it requires that the disk be at least 1GB in size. Is there a reason for this? Or is it an arbitrary limit enforced by OVM Manager?
OK, but it seems like this arbitrary limit provides no benefit. In my case I actually do want a small disk image. I want to use it to pass small amounts of configuration information to a VM at startup, but it seems like this won't be possible via OVM interfaces (I can't create a small private disk image, I can't import an existing disk image, etc). So it looks like I'll have to go under the covers and manipulate the VM image directly.
Am I missing anything? Does OVM Manager provide any interfaces for passing configuration information to a VM at startup? -
Unable to repair degraded Virtual disks in Storage Spaces under Hyper-V 2012 R2 Core
Hi all,
I am finding myself in the following conundrum. I have a storage pool under Hyper-V Core, with 2 2TB Seagate drives.
One of the drives completely died (wouldn't spin up, tried it in a different box, still to no avail). I sent it in to Seagate for warranty replacement, got the new drive. Installed it and went through the notions of adding it to the pool and retiring the
one that was with "Lost Communication" status.
Tried to repair the virtual disks that are showing as "Unhealthy-Detached", quickly get 100% complete, but the repair didnt work.
The storage pool is in degraded state.
Looks like metadata is corrupted.
Followed this post to upgrade Storage Spaces to latest version:
https://social.technet.microsoft.com/Forums/windowsserver/en-US/eead59e9-5e49-4bb6-8cbb-1dafddd9576b/unable-to-repair-degraded-virtual-disks-in-storage-spaces-2012r2?forum=winserverfiles
Still, to no avail.
Couple of questions:
1) Is the data on the 3 virtual disks in state "Unhealthy: Detached" not recoverable?
2) How can I get the storage pool back to "healthy"?
Any help will be greatly appreciated.

Creating a Virtual Disk using Diskpart
Hi, I'm trying to study for a test on Windows 7 and I'm trying to install a Virtual disk and I keep getting the same error. The drive has been "cleaned" using the diskpart utility and is a 300 gb drive. here is the code that I used and the error
as copied from the command prompt. Any help would be great Thanks!!!!!!
DISKPART> create vdisk file="C:\test\disk1.vhd" maximum=24000
DiskPart has encountered an error: The system cannot find the path specified.
See the System Event Log for more information.Hi, slobodan21.
Here is the web page that contains the CREATE vdisk command you have been trying:
http://technet.microsoft.com/en-us/library/gg252579.aspx
I am only guessing but... make sure you create a folder called test in the root of your C: drive.
Good luck!

How to add an virtual disk device
I remember i have seen one doc describe how to add an virtual disk device in solaris system, but I forget it now, can somebody help me?
not sure what you are trying to achieve...
However you should not be referring to Luns via their logical device i.e. c0t0d0, but using the unique did device or the /global device. refer to scdidam -L which will list all the did devices across all nodes and map them to the logical device path. -
Help required with Photoshop Elements 4.0 this has been installed on my new Toshiba laptop with windows 8.1 for some 18 months and operating well. Now it will not open, message pops up saying “attempt to access invalid address” then “application not responding” Suggestions how to access would be much appreciated. Tks. Stuart
What is the size of your hard disk? PSE 4 is a very old program and I suspect it is not able to access the entire hard disk on your machine. Just a thought here.

Server 2012 RC. I'm using Storage Spaces, with two virtual disks across 23 underlying physical disks.
* First virtual disk is fixed provisioning, parity across 23 physical disks: 10,024GB capacity
* Second virtual disk is fixed provisioning, parity across the remaining space on 6 of the same physical disks: 652GB capacity
These have been configured as dynamic disks, with an NTFS volume spanned across the two (larger virtual disk first). Total volume size 10,676GB. For more details of the hardware, and why the configuration is like this, see: http://social.technet.microsoft.com/Forums/en-US/winserver8gen/thread/c35ff156-01a8-456a-9190-04c7bcfc048e
I'm copying several TB from a network share to this volume. It is very slow at ~12MB/sec, but works. However, three times so far, several hours in to the file copy and with plenty of free space remaining, the 10,024GB virtual disk is suddenly taken offline.
This obviously then fails the spanned volume and stops the file copy.
The second time, I took screenshots, below. The disk (Disk27) is marked offline due to "This disk is offline because it is out of capacity". And the disk in the spanned volume is marked as missing (which is what you would expect when one of its member disks
is offline).
I can then mark the disk (Disk27) back online again, and this restores the spanned volume. I can then re-start the file copy from where it failed. There doesn't appear to be any data loss, but it does cause an outage that requires manual attention. As you
can see, there is plenty of space left on the spanned volume.
Each time this has happened, there are a few event 150 errors in the System event log: "Disk 27 has reached a logical block provisioning permanent resource exhaustion condition.". Source: Disk.

This error seems to be related to thin provisioning of disks. I found this:
http://msdn.microsoft.com/en-us/library/windows/desktop/hh848068(v=vs.85).aspx. But both these Virtual Disks are configured as Fixed, not Thin provisioning, so it shouldn't apply.
My thoughts: the virtual disk should not spuriously go offline during a file copy, even if it was out of space. And in any case, there is plenty of free space remaining. Also, I don't understand the reason for why it is marked as offline ("This disk is offline
because it is out of capacity"). Why would a disk go offline because it was out of thin capacity, rather than just returning an "out of disk space" error while keeping it online.Interesting Thread, I've been having the same issue. I had a failed hardware RAID that was impossible to recover in place, so after being forced to do a 1:1 backup, I find myself with 5 2TB hard drives to play with. Storage Spaces seemed like an interesting
way to go until I started facing the issues we share.
So my configuration is A VM Running Windows Server 2012 RC with 5 Virtualized Physical drives using a SCSI interface, 2TB in size that make up my storage pool. A Single Thinly provisioned Disk of 18 TB (using 1 disk for parity)
Interestly enough, write speed has not been an issue on this machine (30~70MB/s, up from 256k on the beta)
Of note to me is this error in my event log 13 minutes before the drive disappeared:
"The shadow copies of volume E: were deleted because the shadow copy storage could not grow in time.Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied."Source: volsnap, Event ID: 25, Level: Error
followed by:
"The system failed to flush data to the transaction log. Corruption may occur in VolumeId: E:, DeviceName: \Device\HarddiskVolume17.(The physical resources of this disk have been exhausted.)"Source: Ntfs (Microsoft-Windows-Ntfs), Event ID: 140, Level: Warning
I figure the amount of space available to me before I start encountering physical limits is in the vicinity of about 7TB. It dropped out for the second time at 184 GB.
FYI, the number of columns created for me is 5

Steven Blom
