• FC zoning in infrastructure ESX 3.5 with Brocade silkworm 200e of and IBM DS4700 SAN

  After reading the guide of config of SAN fibre channel vmware, (Chp 4 pg 58-62 on the IBM DS4000 storage systems), I have a few questions.  First of all, the guide indicates that you must use political multi-channel MRU (most recently used) but when taken with the support of IBM, they recommend using LRU. Does anyone have any experience with this setting?

  The guide also gives an example how to configure a highly available failover of the SAN (pg 59) design.   I wired mine the same as recommended in the guide.  Attached a photo of my situation.  I'm not sure if I am zonine this correctly.  Ideally, I would like to have this zoning configuration in "single-target only initiator" (safer) or single initiator target multiple configuration. He'll just be (2) large VMFS LUNs grouped in a storage of partitions in storage manager that both ESX servers must see so that HA and vmotion work.   Advice to shoot me in the right direction?

  In the Storage Manager, I created a host with a host LNXCLVMWARE type group and is an Alias for each HBA (2 per ESX server) so that I can see the logical drives on the SAN.  I have no configuration of areas now switches from and in the ESX boxes, I can see the disks of SAN storage and add them very well if I choose 'add a storage '.  Target SCSI 0 watch path on disk and when I click on manage paths, the two first show 'dead' and then the last two are 'on' and 'active'. By default, to make these switches multitracks with on any config?

  Someone knows any good tutorials on zoning practices for a vmware environment? I checked what follows, but need more information.

  http://www.yellow-bricks.com/2008/10/28/single-initiator-zoning/

  http://SearchStorage.TechTarget.com/Tip/1, 289483, sid5_gci881375, 00.html

  I have a lot of DS4700 in similar environments, zoning is easy.

  Each host adapter must be zoned to two port controller, for example:

  Host a HBA1 to port CTRL A,

  Host A HBA1 to port CTRLB B,

  Host a HBA2 to port CTRLB A,

  Host A HBA2 to port CTRL B

  In front of ports for host b.

  This is an example, a person prefers to use other combination (ABBA, etc.).

  The result in this configuration is to see 4 paths to each LUN.

  MRU is the only option for DS4000 family, it is the default value for ESX 3.5, take a look at this setting.

  Best practices recommend that you disable AVT for the topology of the LNXCLVMWARE host. I usually haven't changed that. In DS4000 firmware version 7. XX, this setting is disabled by default.

  I also suggest you to remove the LUN ACCESS to the vmware host group.

• Cisco 6248 FI to Brocade 6510 SAN switch shows Link Down

  Hi all

  His new installation of Cisco UCS with Brocade SAN switch 6510.

  I followed the Cisco UCS to Brocade connectivity Guide.

  Even if the switch side so FI link is not coming. No lights are glowing.

  When I checked the switchshow @Brocade 6510, ports are No_Light status display. Where in other ports, it indicates the number of my storage device WWN.

  At the END, when I click on ports CF, its projection on all State - link down.

  Any who are facing this problem. ?

  Am I missing some configuration steps?

  Kind regards

  Praveen

  This should be a trivial or a very complex problem. I'd rather commonplace.

  Brocade is a CF 16 G switch; up to 8 G negotiation seems to work (storage subsystem).

  Maybe you could try to set the speed on the Brocade 8G port fix!

  Or something with the cables is wrong? Send / receive Crusaders?

  Are shortwave of the MMF SFP? cables connection as well?

  Connect cable from port for example. 31-33, 32 to 34 and see if it works?

• Paths always down after returning from a SAN switch at the service

  I had a problem where electricity is cut to one of my SAN switches.  Everything continued to work because all the hosts and storage are connected to a second switch SAN.

  Now that powered the SAN switch back on all paths through the SAN switch are still displayed as out of service.  If I reboot a crowd she restores all of its path through two switches SAN so there is nothing wrong with the zoning on the switch.  I see that the ESXi host host bus adapters connected to the SAN switch, even without reboot, when I do a switchshow (using Brocade switches) and I see that the configuration is correct.

  I tried a new analysis of the HBA, and this removes the paths through the HBA that is connected to the switch that loses power!

  I tried to reset the HBA to get to do a reset of the LIP by publishing: -.

  esxcli fc san storage reset - a < hba >

  for example

  esxcli fc san storage reset - a vmhba1

  and tried to change the State of the railways in assets with

  esxcli storage path together - State = active - path < path-runtimename >

  for example

  esxcli storage path together - State == active - path vmhba1:C0:T1:L1

  None of them have helped and I don't want to resort to restart the host, there must be a better way to bring these paths.

  I use ESXi 5.5 build 1474528.  Want to really upgrade to update 1 immediately.

  I have the advanced of that setting Misc.apdhandlingenable set to 1 and Misc.APDTimeout value 140.  The switch would have been off for more than 140 seconds.  I could try to set Misc.APDHandlingEnable to 0 and simulate the failure once again, but I'm not sure I want to do this because I remember issues with ESX(I) 4.x hosts becoming disconnected from vCenter following situations of CCA.

  Any suggestions?

  I followed it down to the driver used by the Fibre Channel adapter.  I had to update 10.0.100.1 - vmw.550.0.0.1331820 10.0.725.203 - 1OEM.550.0.0.1331820.

  The hosts have been using Adapters Emulex LPe16000 (IBM rebadged in an IBM Flex System).  See 5.5 ESXi hosts don't restore not path storage from the SAN switch failure. Computer services Pelicano so all the details.

• FI6248 FC connectivity with MDS SAN switches problem

  Hello

  We have two FI6248 in a cluster must be connected to two MDS SAN switches, using FC ports.

  However, I am not able to configure the ports on the FI.

  There is no "Set up as FC storage Port" option. I don't see what "configure as FCoE storage Port."

  I have the FC SFP (DS-SFP-FC8G - SW--> 8 Gbps Fibre Channel SW SFP +, LC) installed on the two FI6248 on the first 16 ports.

  No idea what is the problem?

  Kind regards

  The 6248UP unified ports.  The ports can be configured as Ethernet Ports or FC ports.  By default, all ports are of type Ethernet.  The ports that you configure is currently an Ethernet port.  You need config of the ports as FC ports.  Ethernet ports will be on the left side of your FI and FC ports will be on the right side.

  The following link explains how to convert a port UP Ethernet CF.  Since it's on your FI and not a plug-in, you have to restart the FI in last step.

• UCS connection to SAN switches

  I set up direct UCS in the SAN before, but not San switches to connect.  My understanding of the main differences between the two is as follows:

  (1) with SAN switches, you configure VSAN.  To do this, go to the SAN-> SAN Cloud tab and configure your vSAN ID here.  Then in your vHBA template, configure it to use the proper vSAN ID you configured under cloud of SAN.  Nothing else to do here?

  (2) whereas with direct-attached storage connect FI - A SPA and SPB and FI - B to SPA and SPB, with san switches will FI - A ' switch-1' and FI - B is going to "switch-2'."  Is this correct?  If so, anyone know why it should be that way?

  No problem, tbone-111

  As much as I know, that two vHBAs are supported at this time.  It is best to use 1 from the face and side b 1.

  The vHBAs that are used depend on which WWPN you zoned on your boot LUN.

  For the following example, assume the following group:

  1.) my vHBAs are named vHBA_A1, vHBA_B1, vHBA_A2, vHBA_B2 (A tissue face a and B for b-side)

  (2.) vHBA_A1 is the first HBA on my side, and vHBA_B1 is the first HBA on b-side

  AND

  3.) WWPN of the HBA is zoned properly my boot ports storage processor (SP) of the LUN on the FC switch

  AND

  4.) WWPN of the HBA is hidden correctly on my table LUN

  Those are logical, ANDS, they must ALL be true to prevent headaches later.

  5.) disk Array A0 and B1 SP ports are connected to my A fabric FC switch.  A1 and B0 are connected to my fabric B.

  6.) this example of strategy will start A fabric be the path of MBR

  Best practices - FYI, having at least 2 SAN political Boot (1-A-side, 1 for side b and distribute among your Service profiles).

  In my startup policy, I check the will to apply vHBA naming option and specify my names of vHBAs (sorry I have no screenshots available.  Everything started with a new company and do not yet have access lab).

  My primary SAN parameter can be: the main target: wwpn of A0 and secondary target: B1 wwpn

  My secondary SAN setting can be: the main target: wwpn of B0 and secondary target: A1 wwpn

  It would be a good idea to speak with the Admins of storage while you set up the first two servers to boot on each fabric for all troubleshooting.

  If the zoning and LUN masking are configured correctly, you should see WWPN listed during the boot sequence of UCS server to the point where the starting CF driver is loaded.

  Of course, download TAC Cisco on the line, if you encounter obstacles that you can not go beyond.

  I hope this helps,

• UCS Fiber Channel FI for San switch wiring &amp; config

  My question is about the correct wiring & vSAN configuration by the UCS FI switch San (Cisco MDS).

  Currently my wiring is as follows:

  Fi1 port 25 - SW1 port 3

  Fi1 port 26 - SW2 port 3

  Fi2 port 25 - SW1 port 4

  Fi2 port 26 - SW2 4 port

  On the side of the switch San, our guys of storage configured vlan10 SW1 and SW2 as vlan20. For this reason, I was not able to have a vSAN by FI, I read is recommended, because the VLAN switch cross FIs. Now, when I created vHBAs I have 4 vHBAs per server, 2 by IFS by vlan if I want redundancy with a switch or a loss of FI.

  Question: Is this the correct configuration on the side of the SAN switch? Do I actually create 4 vHBAs per server? I do not have my incorrect wiring & I should just be linking FI1 to SW1 on two ports & FI2 to SW2?

  Help or advice would be appreciated!

  ~ Tara

  Hi Tara,

  There are two ways of wiring of your SAN infrastructure.  It boils down to a design decision. Traditionally the SAN admins prefer to keep their separate/isolated tissue.  In this design THAT MDS-1 only connect to FI - A and MDS-2 would connect only to the FI - B.

  Another option is to connect each MDS at each END.  This gives each FI SAN fabric access and allows to create double VSANS (that exists on each FI) rather than separate them.

  You don't need four vHBAs by UCS Server - some adapters support no more than two in any case.   What you do is create two vHBA by the Service profile, each host will have access both to VSAN 10 and 20.  What you can do is to shift your tissue of vHBA while 1/2 access your Service VSAN 10 via FI - profiles and the other half access VSAN 10 FI - B.  This will help to distribute the load accordingly.

  E.g.

  First 1/2 of SPs

  vHBA0 - VSAN10 - fabric-A

  vHBA1 - VSAN20 - fabric-B

  1/2 second of SPs

  vHBA0 - VSAN20 - fabric-A

  vHBA1 - VSAN10 - fabric-B

  As you can see a bit of a manual balancing can act.  The best scenario would be to isolate (re-cable) to your network SAN fabrics according to the traditional SAN design above.

  Kind regards

• Configuration of Nexus 5 k for SAN switching between UCS 6100 s and NetApp storage

  We strive to get our configuration of the UCS environment make start SAN LUN on our NetApp storage. We have a pair of Nexus 5Ks with the company / SAN license on them and the 6-port FC module. What to do to configure Nexus 5000 to operate as the SAN switch between the target storage and environment of the UCS?

• Design of San switch

  Hi experts,

  I SAN switch 6505 and HUS110 connect together.

  But I do not know how to design what is best to connect the wires in the form of images.

  Everything that can be suggested to me that is the best way to choose (method1 or methode2)

  Best regards

  Basically, I prefer Method1. However, you should always check the storage documentation from the provider for supported configurations and best practices!

• activity maintaiance for SAN switch

  Dear team,

  our storage has informed us that these people are planning activity enjoyed in the weekend next, SAN both switches are in redundant mode so no impact of the UPS
  activity on the availability of the San. However ask you to check it out on the side of VMware so all the virtual machines are configured for multipath & are not dependent on the only network SAN
  switch to access the storage.

  all the SAN data store have 4 path (a path is active I/O and rest 3 paths are active. PSP is fixed)

  I just want to confirm if a switch goes down then esxi will automatically route the redundant traffic available SAN switch or do I need manual intervention to route traffic to redundant SAN switch.

  concerning

  Mr. VMware

  
  

  You must confirm if the 4 paths to LUN are in different tissues, cause maybe you feel peckish 4 paths as a single fabric, and if the switch of this fabric must be down you will lose access to the storage system.

  You have two HBA? Each connected to a different switch?

  If you find that your 4 paths in different fabrics and each HBA has access to all the controller storage system processor, you can safety put down one of fabric and ESXi will be managing the paths downwards.

• Connection to the SAN switch upstream

  I'm having a problem getting a green light on the interconnection 6248 (end-host FC mode) and IBM/Brocade FC switch (speed of the 4GB port currently) upstream.

  Side 6248, I have a 8 G 4 GB SFP and SFP (Cisco DS-SFP-FC8G-SW) in the SAN upstream switch. 6248 attached to the FC switch ports are configured as uplink ports? What other measures are necessary for interconnections to see the storage EMC VNX Bay?

  Thank you

  Before that, I discovered that you need to configure ports on the interconnections as CF and not the ethernet ports by clicking "Configure the Ports unified" on the General tab for each interconnection and adjusting the slider, and then select the ports (right click)... At least that was my problem... lol

• Connect FI two directly attach FCoE storage and SAN switches

  Nobody tells me if I can connect FI two directly attach FCoE and SAN storage switches also, as you can see in the diagram of connected network?

  If so, should I FC Switch function Mode? Any concerns should I consider?

  Or the best solution would be appreciated. Thanks in advance.

  The UCS will be in Switch Mode FC, which means that it has a default area.  We cannot make a Zone merge with Brocade because we have no control to set up specific items such as domain and other articles CF IDS that need to be changed when you connect a Cisco FC switch to a Brocade.

  Usually in this situation with a 5 k or a MDS you might be placed in mode of interoperability, which changes the default settings and we will talk to them together - in this case, you can't change these settings, so the only supported configuration is CF Cisco at Cisco.

  See you soon,.

• 10GB with 1 GB SAN switch?

  Hello

  I was prompted to install the below: -.

  • Ps4210x EQL
  • 2 x Dell r430 (with NIC 1 GB)
  • 2 x N2024 switches (iscsi)

  My concern is that we would use a 10 GB SAN with a 1 GB switch (NIC 1 GB on the server).

  My colleague says the Equallogic can connect to the uplink of 10 GB on the switch ports, but the servers will be able to connect to the server to 1 GB.

  I am curious to know if this is considered to be good practice - I don't like the sound of it!

  Huw-

  The PS4210 have 2 x SFP +, 2 x 10 BaseT G and a single MGMT Port.  The BaseT are compatible down to 1 G. Your PS is connectet by 2 x BaseT by controller where a controller is active and the 2nd. is in standby. If you can read 200 MB/s of MPIO depeding how good work.

  It's not a problem because the current line of the PS does not contain specific patterns of 1 G, as well as most in good old day with the PS6010<-><->6000, 6110 6100. If you took a decision when you purchase the device. You get two options in a box and can change whenever you like.

• Adding a user role for SAN switches

  I'll try to find the correct location in 3.3 ACS to add the following: roles = "network-admin". We have our SAN with Ganymede switches +. When one user other than admin connections, you get the role of "network operator". The Cisco MDS 9000 Family Troubleshooting Guide, version 3.x doc explains the role if you are using IOS/PIX Radius. Thank you.

  Hi Ed,

  Here is the link,

  http://www.Cisco.com/en/us/docs/storage/san_switches/MDS9000/SW/rel_2_x/San-OS/Configuration/Guide/cradtac.html

  If you are looking for:

  GANYMEDE + custom attributes can be set on a control access (ACS) server for various

  Services (for example, shell). The Cisco MDS 9000 family switches require custom GANYMEDE +.

  attribute of the shell of service to use for the definition of the roles.

  Cisco ACS GANYMEDE +.

  Shell: roles = "network-admin".

  Shell: roles * "network-admin".

  Cisco-av-pair * shell: roles = "network-admin".

  Cisco-av-pair * shell: roles * "network-admin".

  Cisco-av-pair = shell: roles * "network-admin".

  On GBA, if you go to: the Interface configuration, GANYMEDE + (Cisco IOS), check nex to: "display a window for each selected service in which you can enter custom GANYMEDE + attributes.

  Then, go to the configuration of groups and define the role information according to the above attributes.

  Hope that helps
