• LAG does not not after more Guide of switch Configuration for EqualLogic San steps in the document.

  We use the information provided in the following document: i.dell.com/.../dell-networking-n4000-series-switch-configuration-guide-for-equallogic-sans.pdf

  We have two switches of N4032F which are stacked and followed almost word for Word from this document.  We do not use DCB.  We are trying to set up a SHIFT and follow-up step 2.11 in the document, but it seems that the SHIFT does not work.

  Switch 1:

  serial interface fortygigabitethernet 1/1/1-2

  No spanning tree portfast

  active in mode channel-group 1

  Switch 2:

  interface series fortygigabitethernet 2/1/1-2

  No spanning tree portfast

  active in mode channel-group 2

  However, when it was discovered after changing these settings it shows them as being inactive.

  

  Can someone please help?

  Thank you

  Jeff

  Thanks for the additional information. When the switches are stacked, they act as a logical switch. Then when you plug with an OFFSET you are basically creating a loop and hook up a switch on himself. Desempilement switches and just use the OFFSET for the interconnection of the switch and you should see the GAL go active.

• IBM V7000 SRA command 'discoverArrays' failed. Invalid ID Array. Refer to IBM SAN Volume Controller troubleshooting

  The design is v7000 to unified v7000.

  I created a user full administrator 'sradmin"on two SVC level.  I connected and validated who works at authentication.

  I checked the two intefaces CIM (port TCP 5989) are open and listening on both SAN controllers.  I have a test SRM lun assigned two different hosts in two separate data centers hosted by two separate vCenter servers. The rest of the SRM configuration went well but when I go to 'Add an Array Manager', I get the below error

  SRA command 'discoverArrays' failed. Invalid ID Array.

  Refer to IBM SAN Volume Controller troubleshooting

  The IBM documentation on this topic http://pic.dhe.ibm.com/infocenter/strhosts/ic/topic/com.ibm.help.strghosts.doc/PDFs/SVC_Adapter_for_VMware_VC_SRM_2.1.0 _...

  Page 14 is 90% of what counts and no real details.

  .. .lacks of details on the way to the application (SRM Agent: IBMSVCSRAUtil) is the installation program.  He launched and is vary vague for fields and conditions are not correct (means 'MDisk group ID', which I can only assume that this relates to "mDisk pool" name.)

  The Clint then as an "OK" button that you click and nothing happens.  I don't know if it is or not. She goes to the next screen as indicated in PDF format, but no matter what I input in the areas of tiny... nothing changes... Although now it shows as having agents SRM to SRM (see attachments)

  I hope someone has this work and can explain what I'm missing... I'm sure it's something simple.

  After reaching out to a friend... who happens picked their way through the installation of the IBM SVC (v7000) program to work with MRS. 5.x

  Here is the solution.

  The field noted as "mDisk Group ID" is a numeric value of the ID of Group of replication of remote secondary site SAN (SAN remote) for the 'mDisk Pool"(changed name mDisk group to the Storage Pool, but it's the same thing)

  Attached is the initial tool screenshots install SRM server on each site, to the point that can be reached under SRM as management controller. I hope this will give you enough detail that others can avoid the pitfalls that I met.

  

• Question of EqualLogic SAN

  I'm working on the implementation of a virtual infrastructure.  A cross training for vsphere 4 months ago, so I forgot a lot.  Also, I'm not at all a passage or an expert SAN.  I am an administrator of Windows, simple and clear.  In any case, here is where I am.  I have two two ESXi hosts with 2 network cards with 4 Gigabit ports in them.  They are Dell PowerEdge R710s.  We have a 6000 EqualLogic (forget what model) SAN.  It has 2 network cards two 4 gigabit ports.  All 8 of its ports are connected to 2 switches PowerConnect 6224 stacked redundantly.  2 ESXi hosts have three virtual switches.  1 for management, 1 for IP traffic to clients and one for iSCSI traffic.  Each virtual switch has redundant connections to each network adapter.  The virtual switch iSCSI has 4 of the 8 ports assigned to him (he just seemed to me that the iSCSI would most need, I may be wrong).  Now, management and IP traffic that NIC is attached to a single switch (PowerConnect 6248 switch), this will change in the future.

  Now, my question relates to the EqualLogic SAN.  It seems that only one NETWORK adapter can be active simultaneously, which gives us 4 ethernet ports.  My boss wants that all ports in a configuration group aggregation of links.  I think he is confused.  My understanding of this was a way to connect the switches.  I think he's talking about grouping of NETWORK cards, but I don't see anyway of y to achieve on the SAN.  Each port on the NETWORK adapter receives its own IP address.  So, I'm quite confused.  Are all connections on the San shared so as to increase the bandwidth?  The SAN is also a management IP address.  It's the address I did the iSCSI initiator to.  As I said, I'm not a guy to switch or SAN guy.  Any help would be greatly appreicated.

  All of you two right really.  LAG can not be used with ESX, you can configure load balancing, so it will use all the paths.  You must first update your hosts to the latest generation of ESX given that some important fixes available for the for use with EqualLogic iSCSI initiator.

  There are a lot of details on this forum in this and this thread.

  Please give points for any helpful answer.

• Storage vMotion with Syncrep on Equallogic San

  Hello

  We recently bought 2 San Equallogic (PS6510ES) and turned on synchronous replication between them.

  We use ESXi 5.5 and followed the best practices guide to disable TCP ack and 60 logintimeout value.

  Everything seems to work fine until we tried Storage vMotion/migration and cloning VMS on the San.

  When we did the migration of 2 volumes on the EQL SAN storage (the target volume has active syncrep), the target volume will be out-of-sync and then the storage vMotion will hang sometimes.

  The worst is when such a problem has occurred, all other volumes on the EQL constantly to respond also. All volumes will not respond until we rebooted the corresponding ESXi host (NOTE: simple shut down/power outside the host won't help.) The San EQL will only return to normal after a reboot of the ESXi host).

  If we pause / off the syncrep before Storage vMotion, the problem will not happen.

  Is this normal or not?

  In addition, whenever the problem occurred, the latency of writing the corresponding volume will be dry and we will receive alerts similar to the following:

  connection iSCSI target ' xx.xx.xx.xx:3260, iqn.2001 - 05.com.equallogic:xxxxx - test-volume ' initiator 'xx.xx.xx.xx:xxxxx, eqlinitiatorsyncrep' failed for the following reason:

  Initiator, disconnected from the target when connecting.

  Thanks in advance.

• Update firmware on AN Equallogic SAN on a cluster

  I'm new to Equallogic and need to update the firmware on a PS 6000 SAN that is in a cluster with TWO of SEM, that the firmware needs go to v6.0.7 to v7.0.5

  My questions: I was told that I need to evacuate the SAN (migrate everything out of him) to the second SAN in the cluster, so there is no risk on everything that's wrong in the virtual machine, while the firmware update coming.

  Where am I supposed to go? I checked the workgroup SAN Equallogic and VMWare vsphere GUI Manager interface, and I don't see a place where I can do.

  Any advice will be greatly appreciated.

  We assume that your EQLs have two controllers on the right?  EQL use a controller Active and standby and in the event of a failure of the controller failover took about 10 sec. To survive this event or need a propper configuration of your phys. Switch, hosts and virtual machines. Just follow the installation and best practices.

  Then... a firmware perform the same type of failover. From an update FW flashing the standby controller first, then asks for a 'restart' which performs failover. That the 'new' standby also will Flash.

  All our EQL + VMware configurations remain 10 seconds (4 pings are missing) breakage.

  If you wish to cancel a member of a pool for maintenance it takes something like that

  -Both of your members are in the same pool

  -You create a new and "move a member" of the existing pool in the new. If there is enough space left all volumes is automatically migrated to the existing Member and the last in the pool

  -If the Member is now in your pool maintenance you can perform the FW update

  Its fully transparent and non interruptible for hosts/VMs. But takes a looooonnnnng time finshed.

  If your members are in different pools already and assuming that enough space

  -Use 'move the volume' to transfer a volume of a pool to another. You need to check if there is enough space left

  -Another method would be to activate SyncRep for all Volumes and perform a switch over. If a member holds all the SyncAlternates you can put paused the SyncRep and perform the update of FW.

  In the first 7 months of this year we perform 3 (4?) FW upgrade of our 11 EQLs that currently spans 7.0.6. The process time vacuate trust has never been an option for us.

  The FW comes with a PDF file on how to perform the upgrade and contains some notes so please take a look inside.

  Kind regards

• Exchange 2010 on EqualLogic - VMFS volume?

  Hello world

  I'm just in the planning stages of a deployment of Exchange 2010 (updated 03). Although I attended a good amount of EQL webinars on exchange and read probably each best practice doc out there, I can't get a clear answer on a pretty important point - how best to organize storage.  It is a relatively small exchange deployment (500 mailboxes, 1 PS4000XV, 2 Dell R910 on vSphere 5).

  I can't find a consensus on how to organize storage. Ce_que I speak to you is either A) make data changes a simple disk VMDK (in a VMFS on the EQL volume), or B) doing the volume of exchange data sit directly on the SAN (i.e. RDM or iSCSI Target, so that data exchange is not inside VMFS).

  Everything I read seems to say that the ASM / me tools to be able to speak the volume directly on the SAN, making the B option to go with. I know there could be advantages and disadvantages at the same time, so maybe an option isn't a slam dunk, but there opinions out there on the issue? Best practices?

  There is no 'perfect' here answer.  There is what works best for your situation.

  If you want to take advantage of the DSO / offers ME and most do, then you must use invited inside the OS MS iSCSI initiator to connect to volumes of data and logs.   VMFS or RDM does not work

  .  A feature key with Exchange integration is the exchange administrator may without the GUI EQL access, create a recovery storage group and restore individual mailboxes on the fly from a snapshot.  It is run entirely from the ASM / ME GUI.

  You can also schedule consistent snapshots to check with the ESEUTIL command on another node, thus freeing the Exchange Server.   Here's just a sample of the DSO / ME features.

  In addition, for optimal performance, you would have different cards for VMware iSCSI and iSCSI comments traffic.

  Kind regards

• Need help to attach a SAN volume 10TB

  I have a SAN Equallogic PS4000e network. When I had a physical Server 2008 I was able to fix a volume 6 to on the server and I saw all the 6 TB using the iscsi Initiator in Server 2008. I now have a Virtual Server 2008 and I need to reach a volume of 10 to and see everything to the virtual server. I can add 2 TB using the VMFS 5 but not greater than. I have the config network for ISCSI VMware Setup. I'm not a fan of spanning multiple disks etc. and prefers it appeared to the virtual machine as a single unit.

  I use RDM for the largest 2 TB disks?

  Thank you

  Yes, currently only RDM in physical (pass-through) mode in charge most of ~ 2 TB (up to 64 ~ to).

• Connection of RDM on Equallogic PS6100 volumes to virtual machines.

  Hello.

  I have a weird problem on Equallogic PS6100 storage. Here hoping that I can have some kind of answer or advice to continue troubleshooting and, hopefully, a solution to the problem.

  Goal

  I need the RDM disks to be install on virtual servers through Equallogic PS6100. RDM disks will be used for Windows clusters.

   

  This is my environment infrastructure.

  1 unit of Equallogic PS6100.

  3 modules of ESXi 5.5 servers. (2 NICs connected to the PS6100)

  2 virtual machines running Windows Server 2012 R2 for windows clusters.

  I created 6 volumes on the Equallogic PS6100 but not able to connect 5 volumes on two windows servers. I need all 6 volumes to be connected to two servers as the RDM disks. Somehow the 6th volume gives me a problem that both servers are able to detect the LUN, but I can not install them. In addition, the connections are on ISCSi.

  Once I have installed the 6th volume on one of the server window the other server will be is no longer able to detect the LUN. This is why I can't install this volume on both servers.

  I tried scanning the LUN volumes on 3 servers ESXi repeatedly and still I can not install this volume 6 for both servers. I even migrated windows servers to 3 ESXi servers and always with the same result.

  All the advice here will be highly appreciated.

  Thank you.

  Managed to solve the problem of a work colleague. Problem has been resolved by adding a new controller scsi for the virtual machine. After adding the controller either stop or restart the virtual machine. In doing so, I was able to discover the LUNS and install the disc RDM for servers.

• SAN Performance issues

  Hello

  Background: I have a PS6100XS hybrid.  I have SAN HQ installed on a virtual machine.

  I was wondering if there is a way to monitor the statistics I/O of the volumes as the depth of queue, read/write statistics, etc.  Also, is there a way to see where the current volume resides (SSD or SAS 10 k disks)?  And finally, is there a way to capture the statistics of e/s data in a spreadsheet?

  Thank you.

  Hello

  In SANHQ, you can explore the volume level.   Disk queue depth can be seen at the level of the Member or the pool.

  Re: SSD/SAS.  No there is no way to see what's on the RAIDset RAIDset SAS vs hybrid.

  Re: Stats I/O.  You can print a variety of reports in PDF, CSV or XLS formats.

  Kind regards

• EqualLogic SAN and Jumbo frames

  I can't get the jumbo frames to work on our Equallogic PS6000.  We have the following configuration PS6000-> Dell PowerConnect 6248 (bunk)-> Windows 2008 Server.

  The network cards on the SAN has been set at 9000 MTU, ports on switches are set to MTU 9216 and the NIC on Server 2008 is fixed to 9014 with active RX & Tx flow control.

  When the server connects to the SAN, newspapers account connection iSCSI target to the initiator "172.21.X.X:3260, iqn.2001-05.com.equallogic:0-8a0906-xxxxxxxxxxx-23a001a955452af6-server1" ' 172.21.X.X:49156, iqn.1991 - 05.com.microsoft:server1' managed, using the length of the standard framework.

  When I ping the SAN of Server 2008 with a shitload of 8972 bytes, it works very well.

  C:\Users\system>ping 172.21.x.x f-l 8972
  Ping 172.21.x.x with 8972 bytes of data: reply from 172.21.x.x: bytes = 8972 times<1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="255" reply="" from="" 172.21.x.x:="" bytes="8972"><1ms ttl="">

  Why 8972?  Told that some genius on the internet.  Any help would be greatly appreciated.

  Well we got it to work.  On Server 2008, we have Broadcom and Intel network adapters.  For our tests, we were just using the Broadcom NIC.  Properties Advanced NETWORK adapter, we initially have the value package Jumbo 9014 and it did not work.  So, we opened the Broadcom Advanced Control Suite that came with the NIC and searched and found that there are two parameters that need to be addressed.  There is a jumbo packet definition which has been set at 9014, which is what we wanted it in the advanced NIC Properties.  There is another parameter, MTU, which can be seen on the advanced NIC Properties.  It has been set at 1500.  Once we define to 9000, frames jumbo started working.  We then uncabled Broadcom NIC and wired the card NETWORK Intel and the value of frames 9014 on advanced network adapter properties.  Once we have that frame has worked on this NETWORK adapter, no other measures were needed.  If it's working now.  Thanks to everyone for their help.

• San capacity issues

  I'm looking adding shared storage smb essentials more license. im not dicided weather to go with a virtual san or san of material at the moment. I read a little about the new sva vmware offering or a san hp of Créteil. the 2 questions I have is the 2 TB limit that vmware has. This limitation applies to external shared storage and if so the san, the only solution of partitioning is... also any entry on the sva weather occur near a san hardware

  Ty brand

  Hello.

  In vSphere 5, VMFS volumes can be up to 64 TB in a single measure, so the 2 TB limit is really now just around your VMDK files. VMDK (virtual disks) still cannot be larger than 2 TB - 512 bytes, you use VMFS or NFS data warehouses.

  In vSphere 5, you can use the compatibility mode physical RDM for volumes up to 64 TB of size in the comments. In other words, a guest operating system could have a RDM which is very large.

  Equipment storage VMware uses NFS. The question of performance is difficult, because you most likely get a lot more disks in a SAN hardware. You also compare block vs NFS. Again, it is a difficult question.

  Good luck!
