Link Aggregation in Solaris 11

A link aggregation consists of several interfaces on a system that are configured together as a single, logical unit. Link aggregation

What do you mean by Link Aggregation?

Its the process of configuring more than one interfaces in a server together to a single logical unit for increased network performance, increased Bandwidth & Link Protection.

In other sense its also called as Trunking.

In this article i will explain on how to configure Link Aggregation on Solaris hosts where the uplink is coming from a LACP enabled switch.

Please see the below mentioned steps:

1) Identify the network cards to be created for the link aggregation

root@liael243:~# dladm show-link
LINK CLASS MTU STATE OVER
net0 phys 1500 up --
net3 phys 1500 unknown --
net5 phys 1500 unknown --
net2 phys 1500 unknown --
net1 phys 1500 unknown --

------------------------------------------------------------------------------------------------------------------------------------------------

2) Create a aggregate group aggr1 using the below caommand for net 5 and net 1

root@liael243:~# dladm create-aggr -i net1 -i net5 -P L3 -l active

root@liael243:~# dladm show-link
LINK CLASS MTU STATE OVER
net0 phys 1500 up --
net3 phys 1500 unknown --
net5 phys 1500 up --
net2 phys 1500 unknown --
net1 phys 1500 up --
aggr1 aggr 1500 up net5 net1

root@liael243:~# dladm show-aggr
LINK MODE POLICY ADDRPOLICY LACPACTIVITY LACPTIMER
aggr1 trunk L4 auto active short

------------------------------------------------------------------------------------------------------------------------------------------------

3) Assign Ip to the aggregate port

root@liael243:~# ipadm create-ip aggr1
root@liael243:~# ipadm create-addr -T static -a local=10.63.35.50/22 aggr1/v4
root@liael243:~# ipadm show-addr
ADDROBJ TYPE STATE ADDR
lo0/v4 static ok 127.0.0.1/8
net0/v4 static ok 10.63.16.243/22
aggr1/v4 static ok 10.63.35.50/22
lo0/v6 static ok ::1/128

net0/v6 addrconf ok fe80::214:4fff:fef8:3a92/10

Simple!!!!! Link Aggregation is configured in your Solaris host.

How to find HBA details in AIX, Solaris, Linux, HP-UX , ESX & Windows

For a person who works on Storage, its mandatory to know the HBA details of the host servers.And when you are working on many flavors of OS, its difficult to remember all the commands. This is making me to write & post such an article. I hope this will be helpful for people working on Storage as well as on Servers.

This article will help Storage admins as well as Sys Admins to find details like port speed, wwn no., vendor make and some important other details of HBA cards inserted in their servers installed with IBM AIX, Oracle SOLARIS, HP-UX, Red-hat LINUX and ESX.

The below mentioned commands should display FCOE card details too if its present in the server.

1) IBM AIX

* First find how many HBA adapters are there using the command "lscfg"

------------------------------------------------------------------------

bash-4.0# lscfg | grep "FC Adapter"

+ fcs1 U787A.001.DPM1VHX-P1-C6-T1 FC Adapter

+ fcs0 U787A.001.DPM1VHX-P1-C1-T1 FC Adapter

* Now we can find the wwn no. of each Adapter card using "lscfg" command (the wwn no. is highlighted in red color )

--------------------------------------------------------------------------------

bash-4.0# lscfg -vpl fcs0

2) ORACLE SOLARIS

* First check how many HBA ports are there and if they are connected or not using luxadm command

------------------------------------------------------------------------------------------------------

bash-3.00# luxadm -e port

/devices/pci@1d,700000/emlx@1/fp@0,0:devctl NOT CONNECTED

/devices/pci@1d,700000/emlx@1,1/fp@0,0:devctl CONNECTED

* Now using fcinfo command we can get the wwn no. of hba cards.(the wwn no. is highlighted in green color)

---------------------------------------------------------------------

Host Power-On issue in Oracle T4-1 server from ILOM prompt : Solved

It is the first time i am facing such an issue with Oracle T-series servers. Starting from T1000, i have worked on different T-series SPARC machines like T2000, T3-1, T3-2, T4-1.... and they are all like my pets. It is something more than a normal pleasure that i feel when i work on T-series and M-series SPARC servers. Unfortunate that M-series servers are no more into market except its support and that too, EOSL is almost reached

While working on these servers, I came to know that if any small hardware issue is there, ILOM prompt doesn't allow the host to run the POST itself and it will stay in the same prompt.

There is an easy way to solve this issue which i have already done and got a positive output. Its just like "Cheating the server". Everything is mentioned in detail below with the commands and outputs

When you try to start the Server, the issue appears like the below mentioned

-> start /SYS
Are you sure you want to start /SYS (y/n)? y
start: System faults or hardware configuration prevents power on.

What you need to do is:

1) Go to the Fault management shell to use the fmadm utility, so that we can find if any hardware issues are

there

-> start /SP/faultmgmt/shell

Are you sure you want to start /SP/faultmgmt/shell (y/n)? y

*********************************************************************************

2) You can see the hardware issues after entering the command fmadm faulty and its the same that you can

see from run level3

Lun Allocation from VMAX Storage

Today i got a chance to allocate some storage luns from VMAX Symmetrix storage Array to a Solaris SPARC host. VMAX storage systems are the best Enterprise level storages and the most popular flagships products of EMC. These Storage Systems replaced the DMX arrays which once ruled the world of storage, another old EMC product. They are fast, reliable and gives a better performance

Allocating Luns from VMAX has a different method and its not like that in DMX. Here comes something new called Port-group, storage-group, initiator-group and a masking view

Initiator Group : Its a group which consists of
  Host HBA wwn
Port Group : Its a group which consists of
  front end ports of the array
Storage Group : Its a group which consists of all the luns that need to be assigned to   host
Masking view : Its a view created with a port-group, Initiator group and storage group
  When we want to allocate luns to host, we create a masking view for it..
  Entire host-storage communication takes place through this masking view

Below i have mentioned on creation and deletion of Port Group,Storage Group, Initiator Group & Masking view.

*********************************************************************************

INITIATOR GROUP CREATION
***************************
The initiator group name i am going to create is ig_libg162 which consists of 2 HBA wwn no.

1) Check if the host WWN no. is visible in the Symmetrix at the ports that is zoned from the
switch end. Here i have zoned it to ports 7e:1 and 8g:1

*********************************************************************************

CREATING STORAGE GROUP

****************************

Here i am creating a storage group with 25 Luns of 5 Gb size each.

1) Add a storage group using a device as shown with the below command and check if the devices

are visible in the storage group

bash-3.2# symaccess -sid 016 create -name sg_libj162 -type storage dev 0087

bash-3.2# symaccess -sid 016 show sg_libj162 -type storage

Symmetrix ID : 000194901016

Storage Group Name : sg_libj162

Last updated at : 02:54:22 PM on Fri Aug 31,2012

Number of Storage Groups : 0

Storage Group Names : None

Devices : 0087

Masking View Names

{

None

}

***************************************

2) After this u can keep on adding devices to the storage group depending on the requirement using the below command

bash-3.2# symaccess -sid 016 add devs 0088:009F -name sg_libj162 -type storage

bash-3.2# symaccess -sid 016 show sg_libj162 -type storage

Symmetrix ID : 000194901016

Storage Group Name : sg_libj162

Last updated at : 02:57:37 PM on Fri Aug 31,2012

Number of Storage Groups : 0

Storage Group Names : None

Devices : 0087:009F

Masking View Names

{

None

}

*********************************************************************************

DELETING STORAGE GROUP

****************************

In Similar way like what we did for port group and initiator group, remove the luns first from the storage group and then delete the storage group

1) bash-3.2# symaccess -sid 016 remove devs 0087:009F -name sg_libj162 -type storage

bash-3.2# symaccess -sid 016 show sg_libj162 -type storage

Symmetrix ID : 000194901016

Storage Group Name : sg_libj162

Last updated at : 02:59:55 PM on Fri Aug 31,2012

Number of Storage Groups : 0

Storage Group Names : None

Devices : None

Masking View Names

{

None

}

****************************************************************

2) Delete the storage group as shown with the below command

bash-3.2# symaccess -sid 016 delete -name sg_libj162 -type storage

Delete Storage group 'sg_libj162' (y/[n])? y

*********************************************************************************

CREATING MASKING VIEW

**************************

1) Create the masking view with the proper storage group in which all the luns are added, with

the port group where all the ports are added and with the initiato group where all the HBA wwn

no.s of the hosts are added. as shown in the below command

bash-3.2# symaccess -sid 016 create view -name mv_libj162 -storgrp sg_libj162 -portgrp

pg_7e1_8g1 -initgrp ig_libj162

bash-3.2# symaccess -sid 016 show view mv_libj162
