G5 xserve connected to fibre switch using 2 cables

i have a G5 xserve and 2 xserve raid connected to a fibre switch. at this moment the xserve is connected using one cable but heard that using a second cable will improve performance (increased bandwidth). is this correct?
i remember reading that doing something like that will cause all raid volumes to show twice in finder

You can connect both cables. It will work fine. The double-volume "issue" was fixed in 10.3.4 I believe -- so that's info that's 3+ years out of date
You should see a performance increase doing this.

Xserve RAID with fibre switch and windows

I have a customer who potentially is looking at an Xserve and RAID using a fibre switch with a couple of G5s with fibre cards for speed. They also have a Windows machine that they need to access files, but speed is not an issue. Will the Windows machine be able to see the RAID if it is shared by OS X Server via ethernet or does it need a fibre card? Thanks in advance for assistance!
Mac OS X (10.4.3)

You can turn on Windows (SMB) sharing, or you can connect it directly via fibre channel. Note, if you connect it to the fibre, you can't have it access the SAME volume at the SAME time as the Macs are accessing (heck, you can't have the Macs access the SAME volume at the SAME time without software either), without Xsan and the StorNext file system.

How do I do a telnet connection with a Switch using name or DNS?

Hi guys, I am configuring a telnet connection but i dont know how to do with a name for example: suppose you have a sw names SW1, i want to do ping to that name and do a telnet connection with that name... I dont know if you can understand me, please can somebody help me?... Thanks.
PD1: i have a DNS server
PD2: it is just a practice in PKT.

I want to show the topology, maybe you can undestand better. So, i cant connect PC6 with sw by telnet with also thename BOG_SN1_SW, but server an PC5 cant connect to BOG_SN1_SW.
PD: all topology is in OSPF

Clarification on how to use Xserve Raid and Fibre Channel without xsan.

First let me apologize for not responding earlier to your response, I tend to get busy and then forget to check back here.
Tod, the answer to your question is No, only one computer is accessing the xserve raid files at any one time and that is via Fibre Channel. However I do have the xserve raids set up as share points via ethernet.
Maybe I should turn that off and only access the files with the one computer that can connect via fibre channel.
I never thought of that. I will try that while I await for your answer, thanks again.

I have the following setup:
Xserve: 2x2Ghz Dual Core Intel Xeon, 5Gb of Ram, Running 10.5.8 Leopard Server
Xserve Raid with firmware version 1.5.1/1.51c on both controllers, and
Qlogic Sanbox 5600
Apple Fibre Channel Cards in Xserve, and Mac Pro Tower; Apple 2 Port 4Gbs Fibre Channel Card
Mac Pro Tower-Quad Core Intel Xeon 2.8Ghz, 16Gb of Ram, Running Snow Leopard 10.6.4
Here is the problem.
The directory for the xserve raids keep getting corrup, and I use disc warrior to rebuild them. Is there a way to keep the directories from getting corrupt? I am a few pieces of equipment before I can build an Xsan as that is the ultimate goal, but until then, I just need to be able to have the raids funciton as storage without having to rebuild the directories all of the time.
Anybody have any suggestions?
Thanks

Re: Xserve Raid Mounts, Corrupt Directory tired of rebuilding directory
Posted: Jun 27, 2010 1:25 PM in response to: Todd Buhmiller
Are multiple computers accessing the same data on the RAID at the same time?
If so then NO. This is the source of your data corruption and I'm surprised if you were able to get all your data back every time if this is how you've been running your system. Each fibre channel assumes it has full and sole control of every volume it has mounted, no data arbitration is practiced and data corruption will occur if this assumption is wrong.
The only way this set-up will work is to use partitions or LUN masks so the volumes are accessed by one computer at any time. As long as one computer relinquishes control before another mounts it you will dodge arbitration issues but this is a dangerous game. If you screw up and mount an already mounted volume - and there is no easy way to tell if a volume is mounted - corruption will then occur. Sharing data simultaneous at fibre speeds is what XSAN does and to do this you need it.

Intel Xserve, G5 XServes, XRAID, Promise

+The xserve raids will mount automatically to any computer that I connect the qlogic fc switch to+
This is source of the corruption to your data. Any computer that attaches to a drive/partition via fibre channel assumes that it alone is in control of the drive and data corruption is inevitable.
+Is that the issue, should I disconnect the xserve from the fc switch and leave it connected via ethernet?+
Short answer: YES. The ethernet connections are fine because the server is controlling the file arbitration through the sharing protocol. Fibre channel connections assumes complete control over the partition and no arbitration of the file access is performed. It's like two people independently driving trying to drive the same car to different locations.
Depending on your set-up it is possible for the two machines to see and use different parts of the Xserve RAID storage but they cannot access the same areas without SAN doing the arbitration.
Hope that's clear,

How do i connect my mac mini to a kvm switch using the hdmi to dvi adapter?

I want to connect my Mac Mini using the HDMI to DVI adapter to a KVM switch cable. I have an Iogear KVM switch. The cable from the KVM switch has a male VGA end connection. I have been trying to determine the right adapter to connect the female DVI connection to the male VGA connector. I will be using the Mac mini and a PC running through the KVM switch. This is doable as the iogear switch is compatible with both a PC and a Mac. Any ideas out there? Thank you.

You would need to get HDMI or DVI to VGA CONVERTER, not a simple adopter. The converter requires USP connection for power. HDMI is only digital while VGA is analogue.

If your MIni has a mini displayport or Thunderbolt port yu can get a les expensive mini displayport to VGA afopter.

Sun Cluster 3.x connecting to SE3510 via Network Fibre Switch

Sun Cluster 3.x connecting to SE3510 via Network Fibre Switch
Hi,
Currently the customer have 3 nodes clusters that are connected to the SE3510 via to the Sun StorEdge[TM] Network Fibre Channel Switch(SAN_Box Manager) and running SUN Cluster 3.X with Disk-Set.The customer want to decommised the system but want to access the 3510 data on the NEW system.
Initially, I remove one of the HBA card from one the cluster nodes and insert it into the NEW System and is able to detect the 2 LUNS from the SE3150 but not able to mount the file system.After some checking, I decided follow the steps from SunSolve Info ID:85842 as show below:
1.Turn off all resources groups
2.Turn off all device groups
3.Disable all configured resources
4.remove all resources
5.remove all resources groups
6.metaset �s < setname> -C purge
7.boot to non cluster node, boot �sx
8.Remove all the reservations from the shared disks
9.Shutdown all the system
Now, I am not able to see the two luns from the NEW system from the format command.cfgadm �al shows as below:
Ap_Id Type Receptacle Occupant Condition
C4 fc-fabric connected configured
Unknown
1.Is it possible to get back the data and mount back accordingly?
2.Any configuration need to done on the SE3150 or the SAN_Manager?

First, you will probably need to change the LUN masking on the SE3510 and probably the zoning on the switches to make the LUN available to another system. You'll have to check the manual for this as I don't have these commands committed to memory!
Once you can see the LUNs on the new machine, you will need to re-create the metaset using the commands that you used to create it on the Sun Cluster. As long as the partitioning hasn't changed from the default, you should get your data back intact. I assume you have a backup if things go wrong?!

Macbook pro wont connect to internet using cable, but connects using wifi fine

My macbook pro wont connect to the internet using a cable, but connects using wifi fine. I use wifi at home but sometimes need to use my laptop at work and connect using a cable but it says i'm not connected to the internet?

Mac is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable?

Macbook Pro is not connecting to TV after using Mini DisplayPort to HDMI Adapter Cable. 2010 Macbook Pro, just purchased Mini DisplayPort to HDMI Adapter Cable from Amazon. Link here: http://www.amazon.com/Mini_Dis-HDMI-CB6-Mini-DisplayPort-Adapter-Cable/dp/B003OC 6LWM/ref=sr_1_2?ie=UTF8&qid=1406238976&sr=8-2&keywords=mac+to+tv --When i connect both ends of the cable to the TV and to the laptop, the screen will blink, but then afterwards it will not mirror on the TV. I have tried going to display setting but cannot find the arrangements tab. When i searched "arrangements" a message said, "The Arrangement tab of Displays preferences is hidden because you only have a single display attached to this computer." Not sure how to fix this problem. I have connected this laptop to a TV before, but with a different cable other than the one i just purchased. Any help would be greatly appreciated, thanks.

Found the fix. Still don't know if it was Windows, iTunes, or Norton 360, but this worked immediately for me:

I found a solution posted from Rodfromnework for PC users. It worked for me and easy to do.
Start --> Programs --> Accessories (Right Click on Command Prompt) --> Run as Administrator
then type in:
Netsh winsock reset
Hit enter, restart PC, open iTunes, go to Store
Hope it works for you too.

Hi, I want to use my Capsule just as a back up via wireless. How do I set this up without connecting it with an ethernet cable to either a router or the iMac??

Hi, I want to use my Capsule just as a back up via wireless. How do I set this up without connecting it with an ethernet cable to either a router or the iMac??

I misunderstood what Time Capsule is and had hoped for a wireless backup device that didn't have to be connected to the router.
The TC is a wireless backup device.. it does not need to be connected to the main router..
The problem is the computer.. not the TC.. the computer has only one wireless card.. if your current internet is by wireless.. then you must choose.. internet or backup.
But my other suggestion will work.. get a wireless USB stick compatible with Mac OS.. there are plenty and cheap.. since you are in the same room as the TC they will work fine.. plug it in and load the driver.. taint hard.
You should do the first backup by ethernet though.. wireless is too slow.. once you have that, you will do fine.
Search ebay for wireless n usb.. Mac compatible..

As you can see.. they are getting smaller and neater.
I have no idea if it works .. haven't tried one.. but I have used USB wireless stick on the Mac to overcome this issue.
You will need to set static IP .. not hard but you need to set specifics if you do buy one post again for the setup.

Connect MBP to TV using RCA Cables

Hi. Is there a way I can connect my MacBook Pro to my older TV just using RCA?
Basically I have Red, Yellow and White open ports on my TV and wondered if there was a cable or a converter of some kind that I could connect my computer to and then connect that to the RCA cables.
Thanks!
Message was edited by: crystalfromshawnee

Those are actually composite inputs (the yellow is video, the red and white are stereo audio), not RGB. Depending on what model of MacBook Pro you have, this adapter might work:
http://store.apple.com/us/product/M9267G/A
If your MacBook Pro has a mini DisplayPort connector rather than DVI, then it's been reported that a mini DisplayPort adapter (available from Apple) and this converter:
http://www.grandtec.com/products/video/untimateEZ.html
works, but I have no personal experience with it.
Either solution would require that you run the audio separately, from the headphone/speaker output of your MBP to the red and white inputs on your TV.

Connecting Help using Cable Modem

I am trying to connect to the internet using a cable modem. It works fine on my PC but when I try to plug it in to my Macbook, I can't connect. First off I figured I could just plug it in and hit connect, or it would connect automatically. Because the whole reason I got a mac was because of the "easy-ness" surrounding them. So can anyone guide me to somehow connect.

The problem likely is not your Mac but your cable modem.
Most cable modems, for some unknown reason, lock themselves to the first device they see. This means that if your PC is the first device to use it, then only the PC can use it - it won't talk to the Mac at all.
The first solution is simple - power cycle the modem. This resets the lock so the Mac can use it (as long a the Mac is the first device), but then you have the same situation with the PC.
The better solution is to get a NAT router that can take the connection from the cable modem and share it between both Mac and PC simultaneously. As far as the cable modem is concerned, it only sees the router and the lock does not matter. Numerous vendors make numerous products that will fill this requirement.

Upgraded to Maverick. Now cannot connect to wifi. All my other devices will connect. Have rest wireless hot spot switch and cable modem. Other devices still connect but MacPro does not. MacPro wireless is self assigning an IP address blocking access.

If you follow this video you'll see how to delete your WiFi AP from the OS, this will allow you to select it again which I feel will correct your problem.
