Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Good Morning Experts,

I'm hoping you can help me.

I had a strange occurrence happening when I reboot our Hyper V servers.

I recently replaced the memory on one of our Hyper-V's and still need to replace it on our second host.

When I turned it back on, all of the storage on the virtual systems switched, each virtual had different disks assigned to them, so some of them would not start.  

These systems are using Iscsi storage that is provisioned for this host from a windows server.
All disks were online and available.

For example:  Virtual machine 1 that previously had Disk 9 at 300 gigs, now has Disk 3 at 80 gigs assigned.

I have documented what disks go to what virtuals as I create them, so nothing matched when this host came back on.  I also have documented and labeled what cables go into which nics since everything for storage and network are assigned accordingly.  

We have since matched everything back up but I need to figure out why this is happening and need to install the memory on the other host.

I hope this makes sense, these disks are not clustered.

Thank you,

Hello all,

I have a HP server DL 580 G5, running VMware vSphere 6 Essentials HP Custom version.
The hardware has 2 RAID controllers Smart Array P400. See attach.

Vsphere for some reason can only see the Embedded RAID controller and not the Controller in Slot 10.
I've tried to install the drivers manually but it doesn't seem to work.
However, If I install VMware version 5.5 it can see the controller in Slot 10.

Can some one point me or instruct me on how to inject or install the correct driver for RAID Controller in Slot 10?
I've included a few attachments. The one in question is vmhba4

Pls let me know if you need more information.

Dear experts,

I am supporting a few small dental offices that host the dental application server in house.

Some of this clients  do not have a way to fire up the server that they depend on once there is a hardware failure.

Today a power supply went bad and they are without their application until wednesday.

In other locations you can restore a virtual machine server from a  backup job  from storage.

No such thing here. What is the best solution in case they need a loaner or a image restore program?

Thanks, M
I am getting errors on my vsphere server that states we have hit our SQLExpress size limit.  Because of this we can not connect to the vcenter server.  I have loaded the SQL Management Console and it does show that we have 0% space available.  I have looked to remove old VM's that not is service any longer, which reduced the space used on the Storage server, but didn't free any DB space.  What are my options;
I'm facing some problems with an SD card. Its format is SDHC and I'm trying to format it but I don't have access to it in any possible way. I've tried SD Formatter, Disk Manager, command prompt and I didn't have success. Can someone help me, please? Thank you.
Hi all,

I am currently in the process of putting a logon script together in order to map network drives for users. This should be easy, but the drive mappings will be connecting to storage on another domain - without any trust relationship between the domains.

There is a legitimate reason for the trust not being there, if it was this would be much easier.

Each user has their own logon script (%username%.bat), which has a list of drive mappings using the 'net use...' commands to map to the storage on the second domain. Within the second domain, they also have another AD account (exactly the same username format) with the correct permission to the storage.

My initial idea was to place a script called 'runas.bat' within the 'NETLOGON' area of the domain they're logging into, with a one-liner of runas /user:<secondDomain>\%username% "%username%.bat" - hoping that this would run for each user, ask for their credentials to the second domain, and then run the required %username%.bat for that user to map the drives.

The problem... the 'runas' script will not run against a UNC path, so the script also defaults to 'system32' and the %username%.bat scripts cannot be found.

I have seen suggestions of temporarily mapping a drive letter within the 'runas.bat' script, but this would get messy.

The domain they're currently logging into will soon go, they're in the process of migrating all users, business data, and applications across to the new domain. The data …
This is something I have been searching for an answer to for a while along with trying various things that don't work.
Basically, I want to write 25GB and 100GB M-Disk media and while the articles I've found say that almost any modern writing software will work, none seems to understand the size of the disk.

What writing software for sure knows how to write to these disks, knows how to calculate the amount of data used/left, etc without being stupidly costly or made mainly to copy movies since in my case, I only want to write data disks for long term storage.
I've got 2 T430s, with an Intel Xeon E5-2630 v4 2.2GHz (10 core), 64 GB RAM, a mirrored 300 GB SAS drive for os & 6 2TB SATA in a RAID 10.
Looking to set up Exchange 2016, network version of Quickbooks enterprise, Trend Micro worry free business security, a remote access server, file & print server, as well as the MS stuff, DC (or 2?) DNS, DHCP, etc.
In complying with licensing, I gather the only role I can have on the host is Hyper-V, which is on my 300GB, would any other VM 'parts" go here, as well?
When setting up VMs, does one VM encompass the OS & data, which would normally be on 2 different arrays the 'old way'?
The two directories for VMs would both be on my RAID 10, correct?
Any suggestions on the best way to spread all my pieces between 4 VMs?
If I've got too much stuff here & would be better splitting between questions, lemme know.

Server is running VMware ESXi 6.0
Controller card P420i

We rebuilt 2x600GB SAS drives in a raid 1 to 2x1200GB without any issue.
When trying to expand the disk space on the logical volume it prevents us of doing this or there is no option as it complains there is a 600 GB Hot-spare drive configured to the same array (Array A).
I do not have any option in ACU on removing of Hot-Spare drive, i have the option to erase the drive.
Will an erase of the drive tell it that it is no longer a hot spare drive ?

How can i remove the Hot-Spare drive ? I would like to repurpose it to another Array B as a hot-spare.

Update, i tried to do this from ESX console using hpacucli using command ./hpacucli ctrl slot=0 array A remove spares=2I:2:8
but got Assignable spares not available (see attached screenshot).

Show command on Array A

Hi all,

We have a file server Windows Server 2012 and we would like a tool or script that sends weekly reports of the disk size of each folder on the File server.

Basically the file server is consuming a lot of storage and we would like to have like a dashboard.
Hi we currently have had a failed harddrive in our server i have replaced the drive i no seem to be gettin a warning as posted below thanks chris

Can you please suggest the best and cost effective Enterprise Cloud Storage/Sharing against Dropbox,, and
We are evaluating it for our new project.

I have a box that I configured to use MD RAID during the install process for the OS and boot drive. It's this weird /dev/md0p# structure that confuses me.

The installer produced /dev/md0p1 (/boot), /dev/md0p2 (/var/lib/mysql), /dev/md0p3 (/), /dev/md0p4 (extended), /dev/md0p5 (swap). I noticed it did this for all physically installed machines from the CentOS 6 DVD.

How do I increase the size of the /dev/md0p3? I need this root partition to be expanded. I feel like I need to delete the /dev/md0p3, /dev/md0p4, /dev/md0p5 partitions and then create a new one for /dev/md0p3 with the extra space. I don't care for p4 and p5, because they don't contain actual data. I can create them after the fact.

I am confused on the order of deleting partitions and adding the space in respect to /dev/md0. fdisk -l shows the drives /dev/sda, /dev/sdb and then finally /dev/md0 with all of the sub partitions.
On Exchange 2007 how do I move part of the storage group maybe half of it to a different drive?
I have large numbers PDF document, from which I need to extract text. The extracted text I use for further processing. I did this for a small subset of documents using Tesseract API in a linear approach and I get the required output. However, this takes a very long time when I have a large number of documents.

I tried to use the Hadoop environment processing capabilities (Map-Reduce) and storage (HDFS) for solving this issue. However, I am facing problem to implement Tesseract API into the Hadoop (Map-Reduce) approach. As Teserract converts the files into intermediate image files, I am confused as to how intermediate result Image files of Tesseract-API-process can be handled inside HDFS.

I have searched and unsuccesfully tried a few options earlier like:

    I have extracted text from PDF by extending FileInputFormat class into my own PdfInputFormat class using Hadoop-Map-Reduce, for this i used Apache PDFBox to extract text from pdf, but when it comes to scanned-pdf's which contains image, this solution does not give me the required results.

    I found few answers on the same topic stating to use -Fuse and that will help or one should generate image files locally and than upload those into hdfs for further processing. Not sure if this is the correct approach.

Would like to know approaches around this.
i am trying to acquire data from the lock-in amplifier in interval of 1 millisecond or less.

I have IBM server 3650 with 4 hard disk install slot no 1,2,3 is have HDD 750GB and they are in raid 5 and the same array.
in addition. the slot number 4 have hard disk 300 GB this hard disk was faulty I have removed and inserted into the running server and it went to an orange solid light and flashing green light. I assumed at that time it was rebuilding the drive. it is still it rebuilding the drive.

Moreover, I found one partition disappear

Does anybody know why the light is flashing green light? on the drive?  Any suggestions for?

I am using 15GB of my 15GB G-Mail allowance. I have done all the easy stuff but have lots of IMAP folders that I can't trim down much.

365 seems to give you 50GB storage.

After suggestions really. I have a Dropbox Pro account and Amazon S3 too if anything there that would help.

Just need too find some solution of getting the IMAP folders somewhere easy to manage. My preferred client is Outlook (using 2016 on Parallels on my MBP).

Any ideas appreciated
One of our Exchange servers is running out of space on C: (Exchange 2013 on Server 2012R2)  Investigation finds 36GB in System Volume Information, apparently in ShadowStorage:

I suspect some involvement by DPM 2012 which is used to backup this server, but have no real evidence to support that...

I had this question after viewing What's the maximum limit on the MBR - NTFS drive to be extended ?.


I've got some serious issue here, after rebooting the server for some exchange service issue, now the D: drive which is 1.9 TB as per VMware VMDK size, is not showing accessible as NTFS.

it is now becoming RAW.

I tried to run CHKDSK D: but it is not working due to the filesystem is now RAW not NTFS.

Any help please ?

This is impacting my Mailbox Database for Exchange server.
The D: drive is VMDK running on iSCSI SAN (HPE lefthand)
I have a Windows 2003 SP2 server which is running Sanctuary (Lumension) client 4.3.25 used for application and device control.

Recently the service has failed and will not restart. When starting the service it will run for a few seconds and then stop.

I have enabled the SCOMC logging and the log file shows the following error:

"Error 1 querying storage device number"

So far the following troubleshooting has been attempted with no result -

 - Server was rebooted
 - Sanctuary software reinstalled on the server.
- Checked service settings and accounts etc.
- Compare SCOMC reg settings to a working server and added any missing keys.
- Ran PROCMON but unsuccessful in identifying any issues.
- I have replaced all the .exe and .dll files with the Sanctuary\Cient  folder from a working 2003 server.
- Also looked at the disks on the server. Some are presented by PowerPath. One SAN attached disk which was offline was removed.

Has any one see this error before?

Many Thanks.
