Essbase on San Drive

We have installed Essbase in SAN drive. It was working fine for past 2 years recently we have noticed some abnormal behaviour on the calc performance. The same calc takes 2 hrs in the morning but if we run at around 6 pm takes 4 - 5 hrs. I(there is no backup process running at 6 pm).
Any suggestion what needs to be check to find the issue?

Hi,
As SAN setup is a common storage setup for all the applications/systems of an enterprise. It might have some maintance issues ..which might impact our essbase environment.
But, I personally would prefer to have the installation of an application ( like essbase on the local drive of the server ) and distribute its storage across the SAN drives( as my storage requirement for essbase might be huge, and might beed in TB's ,which is possible only through SAN).
Its more important for an applications performance that SAN is configured optimally for performance. There are few parameters at SAN end like
1. Raid configuration( EX if its Raid 1 0 , though its more expensive , its faster ).
2. How the LUNS and LUSE 's have been assigned
3. Count of spindles ....etc
This is what I can add, hope its useful

Using final cut on a network SAN drive

We have Final Cut Pro X installed an new iMacs at the college I work at. We installed Final Cut Pro X 10.0.1 under Mac 10.7.1 and added a network SAN drive to store Media files and it worked perfectly. We then upgraded to 10.7.2 because of network problems we were having with the Macs and now whenever you go to add a SAN drive, all the folders on the network drives are greyed out.
We run the Macs using AdmitMac to connect to the network, it's not a permissions problem as the Macs can read and write to the drives via the finder and we definately do have a SAN in our building to store edited videos.
This is causing us a headache because of security the Macs cannot write to the local drives of the machines and only to the network. It's a real pain because we cannot use Final Cut Pro X at all at the moment. Anyone got any ideas?
We have tried with machines without admitmac and it doesn't work. The only thing we can think of is because of the new security implemented in 10.7.2 for network drives, that might have something to do with it. Like I say the major variable between it working and not working is the Mac OS X update.
Can any help with a workaround that doesn't involve creating a DMG on the network? Please help!

FCP 5.0 is the PowerPC version. That and lower. FCP 5.1 is the Universal version.
Where are you storing your media? Your captured footage?

Recover point - SAN Drive Replication DR Test

Just want to share our DR Test exercise which i am involved in, SAs are trying to replicate SAN Drive/Server on 2 places, server has the same name & IP with recover point.
That was my understanding about recover point.
we should be seeing the duplicate on another set of disks on another server, within DCX ( the server can be called the same, but diff IP for that server.( but i say same server name & IP on both ends)
Any body can help me clear my concepts about this?
That was the steps SAs/SAN engineers done
DNS was activated
domain controller was activated
tulppsh05 was successfully built from makesysb
tulpcorbadb02 was successfully built from makesysb
wmstutps01 was restored from symantec
citrixbox (name?) was built
Replication issue with SAN drives was resolved

My answers:
1. The restore command can restore datafiles belonging to tablespaces or control files or spfile and will do this at the right OS locations but it cannot restore online redo logs because RMAN does not back online redo logs.
2. If you are testing disaster recovery, you should test loosing all database files on disk (control files and datafiles and redo logs and spfile): it means that you can only do incomplete recovery since transactions committed in redo logs are not in your archived redo logs backups. So, yes this is point in time recovery.

Configuring SSD as a boot drive

Hi!
I've finally ordered a six cores Mac Pro and I'm waiting for a SSD from OWC.
I intend to use the SSD as a boot drive so I plan to copy the content of the Mac Pro boot drive with SuperDuper when I'll receive it and restore it to the SSD.
I've read few comments here from users who says that could be a risky operation doing so due to the fact that a SSD doesn't behave as a regular hard disk. I'm a bit skeptical because it is a very common operation to backup and restore a boot drive.
Anyone has used SuperDuper with an SSD ?
Thanks!

I don;t see why it would be a problem. But then again I'd be more inclined to just re-install using the DVDs that come with your new Mac Pro. After all you have no data to save at this point, so doing a fresh install is just a nice simple process.
Tom
I'm not familiar with the Mac Pro and the supplied DVD. There is no special driver or configuration specific to the Mac Pro already installed on the HD ? The regular install DVD would do the job ? If so, you're right. It is a lot easier just to reinstall from the DVD.
Many thanks.

Configure SSD as window boot drive

Hello HP support Forum.
I have a Pavillion p7 - 1240 desktop. I installed 120gb SSD drive. Window 7 recogizes SSD drive as regular active drive, but not as a boot drive. I want to configure 120 GB SSD as boot drive and 1.0 terabyte HDD as storage. How do I go configure Window 7.0 Home Edition to boot from SSD ?
Please Help?
thank you

Hello Lasvegaswireman and thank you for responding and helping with installation of 120 Gb bytes SSd.
I did a clean installation of bare bone Window 7 Home edition - on SSD drive. window was able to boot up successfully without any error messages.
However, window 7 does not recongnize or detect external 1 terabyte backup usb drive when I plugged it to USB port ; backup drive has power as indicated by LED on. I were unable to restore backup file from external USB drive because - USB controllers, network adapter and all crtical configurations of the orginal HP factory settings were not loaded; as the result, I were not able to use usb port restore computer setting from backup. it's a bare bone Window 7.0 Home edition 64 bit. No internet connection detected.
I pondered the mirror image backup of my internal hard drive, but the size of mirror image is 190 gigabyte, which is larger the capacity of the 120 gbyte SSD.
how do I work around or resolve this problem? I had not format the orginal internal 1 terabyte hard drive yet for fear I might loose settings should I fail to restore files and data from external usb hard drive.
I used Microsoft provided backup that comes with Window 7. How do I load and restore all drivers and settings from USB drive onto SSD drive , and use 1 terabyte HDD as data storage.
I have not formated internal 1terabyte hdd yet for fear of loosing all settings and configurations should I fail to restore data from external backup.
Would you show me how to resolve or work around these issue? I want to get larger capacity SSD to accomodate mirror image but it is costly for budget.
I thank you for your help, and I am eager to get resolution.
Cordially Yours.

Capturing OnLocation to a SAN drive

Is anyone capturing through OnLocation to a network drive under a SAN?
I'm talking SAN, Storage Area Networking like Fibre or iSCSI, and not NAS, Network Attached Storage like some cheap ethernet box.
Why do I ask this? I recon that this may be the best forum to launch into some network storage issues when recording in a studio or at an event.

Kevan
Any luck on this subject. I want to use a raid server to capture approx 20+ hrs of video for a dance competition with the ability to use the server to copy files and produce DVD's on site for my customers. Others in the industry use OnLocation but do not produce on site.
Thanks

How to mount SAN drive inside Solaris 10

Dear Support,
I have some solaris servers, and storage administrator have given 1 of the solaris server 4 LUN. I will need to mount those drives inside my solaris servers. I would like to know how to do it step by step.
Anyone can guide me?

1. After I do rescan with DEVFSADM and I do sympd list will device appear?
hostname#echo | format :
Searching for disks...done
here you can able see non labled disks. you need to labled first. after labled, here you are not see disks.
AVAILABLE DISK SELECTIONS:
0.c0t0d0
2. How can I see the device prior to formatting and mouting it?
After labled, you need to create the new file systems with user : newfs /dev/rdsk/c1t2d0sX
cerate mount point: mkdir /test
mount /dev/dsk/c1t2d0sX /test
3. From the FORMAT command how do I know which is my new device as the server already has plenty SAN disks assigned?
A): hostname#echo | format :
Searching for disks...done
here you can able see non labled disks. you need to labled first. after labled, here you are not see any disks.
AVAILABLE DISK SELECTIONS:
0.c0t0d0
4. From the FORMAT command how do I tie devices back to a SAN/Symmetrix device number?
echo | format | grep c1t2d0 (SAN device name)
5. Then the easy part to the guru's how to I physically map/moun the newly added device?
you have fallow the above steps..

SANE driver (or other software) for my film strip scanner?

I took advantage of a cheap (£40) offer from Aldi and bought a "Tevion Film Strip Scanner" which nominally is only meant to work on Windows XP and Vista. On Arch, lsusb identifies the device as:
Bus 001 Device 004: ID 05a9:1550 OmniVision Technologies, Inc. VEHO Filmscanner
and it looks identical to the particular model: Veho VFS-004
I've done quite a bit of searching, and found some hints in forums that SANE might support it, but no evidence of this on the SANE site. Also, Avision drivers for film scanners were mentioned, but no go either when I tried to tweak /etc/sane.d/avision.conf with the device info. Also, I tried the VueScan program which was also hinted to work, but got "scanner not found".
I do have access to Windows to use the device on, but it would be great if anyone knew how it could be accessed on Arch.

Anybody know what make is in the Apple Store configured SSD for new MacPro?

Hey there,
Does anybody know what make and model Apple is putting into their new Mac Pros?
At Apple Canada it is a 512GB SSD that costs an extra $1340 to add to your custom build.
I really like what I've read about the OWC SSD below:
http://eshop.macsales.com/shop/internalstorage/Mercury_Extreme_SSD_Sandforce/Solid_StatePro
My question is the quality vs. price arguement:
Apple config = 512GB $1340 CDN (?? make and model of this SSD ??)
OWC config = 480GB $1599 USD

They are not really good SSD drives.. they are SAMSUNG and are very much so, inferior compared to the OWC SSD drives.. do yourself a favor - don't waste your money on stuff that won't work right.. Get the OWC + save $$$

SAN boot configuration - Targets

      I have configured the Boot Order to point to a specific target for vHBA0 (Primary) and vHBA1 (primary), assigned it to an "Updating" Service Profile template, then create the service profiles from the template. Works like a champ.
Now for the wrinkle, on the VNX this works as I have one set of targets for the boots, however now add a VPLEX where you distribute the targets to prevent a boot storm and now I need to make some changes.
I now create an "initial" Service Profile Template, create 4 different Boot Policies, create service profiles from the template, then modify the service profile to add the Boot policy that matches the target of the storage.
The question:
Since I can define a target and a boot LUN on the wwpn. Can I define a boot policy that only has vHBAO and vBHA1 without targets (to enable them for boot) and will the server boot from the target defined on the wwpn's? This way I can just create one Boot Policy and add it to an updating service profile template for those servers on the VPLEX.

Just a clarification:
You have initators eg. vhba0 and vhba1 with pwwn which are used for
     1) zoning
     2) lun masking / mapping, eg. initiator with pwwn a -> lun 0
Bootpolicy
     1) specifies the outgoing adaptor, e.g. vhab0
     2) specifies the pwwn of the storage subsystem controller
Typically, a storage subsystem has 2 controllers 1 and 2; and each has at least one (or more) interfaces in fabric A resp. B.
This applies to VNX, and if you use VPLEX, you just introduce an intermediate virtualization layer to hide the VNX; the concept is the same.
To avoid that in a boot storm, all the traffic would flow over the same hba and storage system port, you have to define multiple bootpolicies. I don't know if any other solution.
e.g. Boot policy nr. 1
hba0     -> primary controller 1 port 1 Fabric a
              -> secondary controller 2 port 1 Fabric a
hba1     -> primary controller 1 port 2 Fabric b
               -> secondary controller 2 port 2 Fabric b
e.g. Boot policy nr. 2
hba1     -> primary controller 1 port 2 Fabric b
               -> secondary controller 2 port 2 Fabric b
hba0     -> primary controller 1 port 1 Fabric a
              -> secondary controller 2 port 1 Fabric a

Configured SSD from MBP to MP??

I have a MP ordered and currently using a late '08 MBP with 240GB SSD. If I purchased a 3.5 to 2.5 adaptor for the SSD, could I put the SSD in the MP and have it boot the machine? I'm just trying to get out of migration and since I won't be using the MBP anymore, I was thinking that would be a good way to make use of the SSD. I know the SSD will fit, but I didn't know if the MP would boot, since the OSx is machine specific.
Let me know what you think
Paul

Thanks for the help, I was hoping that this would be the case. I apologize for taking so long to get back with you.

Sans Digital Drives with Snow Leopard-Anyone??

Hey Anyone using Sans Digital drives (USB) with Macbook pro and Snow Lep.
USB drive is crashing my system as soon as I plug it in
Any Help???
Matt

Sans Digital has not tested these drives with SL-every time I call them-they think their drives just should automatically work -oh well
Well what is happening with my drives is- I have a Sans Drive that has 2 HD in it -when they are running separate they will mount fine by USB= once I go to disc utility to rad them together in a mirror raid --once the OS mounts them -SL crashes and here comes the grey screen.
Anyone having issues with the raid control in SL --I had these problems with reg leopard as well but I guess with updates it turned out working just fine .

If I partitioned my drive from within a bootcamped windows volume will it destroy my GPT scheme and disable my booting ability into Mac OSx?

Alright I consider myself a fairly computer literate person but do excuse me if this issue is not actually all that interesting. Know that I would call apple care but what I am trying to do isn't exactly supported by them so they wouldn't help me. I am setting up my system to triple boot. I did the normal method as far as I can tell. I used bootcamp assistant to shrink my drive and installed windows through that. All went well. So then I had a apprx 400gb mac os volume and a 100gb windows volume. Following the advice from the mactel team over at the ubuntu help site I logged into windows via startup+option. When I did this all volumes popped up. recovery mac and windows. selected windows and then used the windows disk utility equivalent to shrink that partition in half. When I did this I check the disk manager and all was well. all volumes were there and healthy. When I restarted my computer in the boot manager window though only the recovery boot and the windows boot showed up. After doing a little research I figured that the error was negligible and that I could fix it easily enough later so I proceeded to then format the free space volume into an ntfs for the ubuntu setup. When I did that and restarted only the windows boot shows up in the boot menu. When I look through disk manager all of the partitions are where they should be and healthy. The only real clue I've found is that when inside of bootcamp control panel instead of the different volumes showing up as they are normally supposed to it gives me the option of startup from the windows volume the ntfs volume and a pseudo volume that doesnt physically exist that serves the purpose of windows recovery. This makes me think something went wrong with bootcamp. I would rEFIt it and try to see if theres some magic I could work in there but I can't install that program on windows. Additionally I found out that theres some talk that ssd can only handle two bootable partitions and that perhaps when I added a partition it shifted priority to volumes 2 and 3 instead of 1 and 2. I've tried all of the bootup tricks i know and some I looked up. the only one that still works is the boot manager window. The rest just do nothing and then go straight to windows which makes me thing if something happened with bootcamp that all the very low level osx to setup and then run windows on top of that- that now the operation isn't running as planned and windows is actually touching the hardware thus subverting any attempts to use low level osx tricks to get around it. Anyway those are the facts and my thoughts.
Having done more research than when I originally wrote ^^ I now realize that the entire reason for bootcamp (sans driver issues) is to deal with the difference between the use of GPT and MBR. I am now pretty sure that rewriting any part of the drive from software that uses MBR will mess up the partition scheme of the entire drive. Additionally I've seen a few things about ssd's being weird when they have too many partitions on them. And lastly I have an iso image of my computer right before I started tinkering so if anything I can factory reset and voila(I don't feel like pulling up a french keyboard).
picture from disk manager in windows

I actually managed to get the setup running and relatively stable. There were alot of random issues and quite honestly I was fixing my computer more often that I was using it so I backed out. If anyone wants to do this like I did I would say: It's not easy and definitely not for someone who doesn't know anything about the differences between operating systems and partitioning schemes. That being said I didn't know nearly enough and if you're careful its possible. The steps however aer pretty simple.
Before doing anything get a third party boot handle up and stable on your machine.
1. Create a partition for Windows
2. Create a partition for Linux
3. Bootcamp Windows. This step can be tricky with the extra partition because bootcamp tries to handle all of it for you so it may benefit some people to bootcamp first and then create a linux partition. But that comes with its own set of issues.
4. Run Linux setup from inside of osX NOT windows.
There are a hundred steps that could come between each of those and I neither have the expertise nor the balls to empower someone who needs to read a forum post how to do it. But it really wasn't more conceptually complicated than that.
Now on to the new issue. I was getting .NET framework incompatibilities and the whole reason I wanted the windows setup was to game so I deleted that partition. When I did that everything went back to normal EXCEPT somewhere somehow the windows boot manager is still buried and when I boot up it tries to boot into windows which obviously doesnt exist anymore. Any advise on how to get rid of this?
to make things clear I'm now running "single" partition.
