Equallogic PS 6100 reset to factory and setup

Hello,

 You first set it up on iSCSI side then you can enable the Mgmt port address.  The mgmt port is ETH4, not ETH0.

There must be a cable connected to ETH0 and the light lit

 However it won't be enabled until AFTER you enter in the IP, netmask information.  Then it will bring that port up.

 I would first do the array reset again.

 Then try the setup process.

Regards,

Don

Ok. Thank you for the prompt reply. I just reset it again and will try your suggestion. 
So the management port should eth4 and should be plugged in to switch as well? Am i getting it right? 
thanks 

Hello,

 Sorry you found it confusing.  If you had the Remote Setup Wizard software, you can do it from a Windows PC or Linux.  It will search the network for unconfigured EQL arrays.  Then you can do it via a GUI.

 I like the Equallogic personally.  Even when I first started there I was an outside contractor.  The GUI was quick and easy to configure everything.  I was lucky enough to get hired a full time employee after that.

 I am so glad you got it working.  I was glad to be of assistance.

 Regards,

Don

Seems to me that solve the problem. Thank you for your help.
What came to mine mind after that - If you want to meet illogic - go get an EqualLogic :) JK

there is no problem with EQL there is a problem with me :) came from NetApp world and I am  cli addicted person
not gui. :) thanks a lot  

Hello,

 Then you are in luck.  All the features of GUI are at CLI too.

 The online help has a link to the CLI commands.  But you will figure them out quickly as it's consistent.

 Basically Group level commands.  grpparams and member level commands

GrpName>grpparams show

GrpName>member select MEMBERNAME show     MEMBERNAME is what you called it during setup.

 e.g.  GrpName>member select Production-Member-1 show  (general stats)

GrpName> member select Production-Member-1 show eths

There's TAB completion for member or volume names and ? will give you a list of options for that command.

member select Production-Member-1 show ?

I too prefer CLI to GUI. I was raised on terminals  LOL

 Have a great night.

the phase 2 started :)
I am trying to configure networking properly and it drives me nuts.
There are 5 interfaces one is dedicated to management and 4 for iscsi.
However one on iscsi side configured with management network (on 10 other units).  I am trying to understand the architecture of communication inside the unit to setup it properly. I was able to run web interface grp admin but have no luck connecting SAN HQ from management host which is on the same subnet. 
Any idea how it supposed to be done including all pieces SAN HQ management interfaces and iscsi interfaces.
Thank you in advance. 

Hello,

 There are two "modes" for management on PS arrays. With and without Dedicated Management Enabled. That last Ethernet port only works properly when it's configured as a Management port. 

 WITHOUT Dedicated Management Feature:

 The four Ethernet ports (ETH0-3) all provide iSCSI traffic AND management functions.  Though typically you use the Group IP / Discovery address for most operations.

 WITH Dedicated Management feature ENABLED:

  The iSCSI ports (ETH0-3) no longer support any management operations.  No GUI, or SSH, etc..  Those ports now only handle  iSCSI traffic.   All Management operations will now use the Group Management IP address.  Also known as the Management Well Know Address. (MWKA)    

  SANHQ needs access to the "management port" of the group and members.  So if you are NOT using Dedicate Management, that's the single Group  / iSCSI Discovery IP address.  If you DO have Dedicated Management enabled, then SANHQ must use the Management Well Known Address (MWKA) instead.

 You should not have some iSCSI ports on arrays with a Dedicated Management port on your LAN IP subnet this could put iSCSI traffic on your LAN.  Which could impact performance.  Ideally all iSCSI ports are on the same IP subnet.  Otherwise you must route those networks to maintain proper function on the array.  Any iSCSI port will be used to reach any other member or server accessing the group.  Routing adds latency and potentially a performance bottleneck and point of failure.  If that router fails it could impact many servers.

 In SANHQ when you add a group, that registers that server on the PS group automatically. You have to connect it to the proper management IP address depending on the Group configuration. Whether Dedicated Management is enabled or not.

Don

Hello,

 You absolutely CAN reconfigure IP address w/o a reset.

 Since you are changing IP addresses disconnect any servers first.

 First disable the Dedicated Mgmt feature so Mgmt is on iSCSI subnet

 Then pick an interface like ETH3 and put it in the new IP subnet for iSCSI.

 Then change the Group IP address to be on the same IP subnet as ETH3.

  Then change the other iSCSI Ethernet ports to be on the new iSCSI subnet.

  Finally re-enable and configure the Dedicated Mgmt port on the network you want it on.

There are some threads here in this forum on how to change the IPs using the CLI.

 Regards,

Don

thanks Don, 

this is the logical way. 1 port is on management  (once I enable it) and 4 on iscsi. and SANHQ Should connect to IP of management port. This is what I thought. Seems to me I have to blow everything away one more time. Too bad can't simply reconfigure Group IP and etc.

 WITH Dedicated Management feature ENABLED:

  The iSCSI ports (ETH0-3) no longer support any management operations.  No GUI, or SSH, etc..  Those ports now only handle  iSCSI traffic.   All Management operations will now use the Group Management IP address.  Also known as the Management Well Know Address. (MWKA)    

 What really confused me is configuration from old nodes I am working with.
Group has two IPs and one is on iscsi subnet. Another is in management network.   
And this is where confusing came from - what IP should be assign to group at the initial configuration? 
I was assuming it should be management network.

Hello,

 When you enable Dedicated Management is when you get that 2nd "Group IP " address.

Technically what happens is instead of having a single iSCSI discovery address and Management address you have two since they are on different IP networks.

 So the one for iSCSI address Discovery and login process.

 The other is strictly for Management functions.  So when adding in a group you need the Management address.

  Your screenshots haven't shown up so I can't comment on it.

  If this is new group, then just assign an iSCSI subnet IP address. Then enable the other as well  Access the EQL GUI and configure the Dedicated Management.

 Regards,

Don

Ok, it is phase 3  

1. I configured as I think it is supposed to be.  
ETH0 was configured with iscsi IP address 172.20.10. 10 
Once it is up and running I used GUI to enable management network on ETH4 and set IP 192.168.200.153

I can use web browser to connect to storage using java based app, but there is no luck using SAN HQ. It will not be able to connect to the storage by any IP. 
What I am doing wrong? 

thanks
