DG Creation in VXVM !!!

In this month, let us discuss about Veritas Volume Manager.
So let me start with Disk group creation in brief with steps.

While bringing disks (luns from storage) under Veritas Control we will face a common error message :
VxVM vxedvtoc ERROR V-5-1-11177 error writing EFI partitions
VxVM vxedvtoc ERROR V-5-1-11170 Unknown problem reading EFI VTOC

This is because VTOC of a particular lun is not yet labeled. So first of all label VTOC of all the luns before bringing them under veritas control....

In my following server I have installed VRTSvxvm 6.0 version and also added 6 luns from EMC storage.

STEPS:

1. Bringing disks under Veritas control.
2. Initializing disk group.
3. Adding disks to disk group.
4. Creation of volumes.
5. Making filesystems.
6. Mounting the filesystems.

SNAPSHOT from ILOM by CLI and GUI !!!

Snapshot is a utility provided by ILOM to collect SP(Service Processor) data in High end servers like T-series and M-series.

To run the snapshot, we have two methods :
1) ILOM CLI (Command Line Interface).
2) WEBGUI (Graphical User Interface).

Let me start with ILOM CLI, In CLI we use ftp or tftp protocol.
For this we need to login to ILOM.

Oracle(R) Integrated Lights Out Manager

Properties:

dump_uri = (Cannot show property)
encrypt_output = false
result = (none)
Commands:

Here we can observe dump_uri which means, where the snapshot dump should be generated.
So we need to set this dump location.

NOTE: Since snapshot is a large file,ensure the size of desired location before setting dump_uri.

Done.

Now Go and collect the zip file of snapshot from provided directory (/tmp).

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

Next is GUI method :

IN GUI method, we need to login to ILOM ip from browser url :
https://ipaddress/

Soon after entering credentials we can login to ILOM and can see a page as shown below :
NOTE : In screens observe the highlighted red box.

Then click on ILOM Administration :

Now click on the maintenance:

After clicking on maintenance, a page will be loaded then select the snapshot :

Then we can observe the option " Run " , click on it.

Now we need to select option " save " the snapshot in our local PC :

Lastly we need to select our desired location to where our snapshot should be downloaded:

Once download gets completed successfully, we can check our given location " My Documents " for the snapshot file.

Configuring Control/Service Domain !!!

Soon after creating a control domain, we need to make it a service domain so that it can provide virtual services (such as disk drives,switches) using all the resources to guest ldoms.

root-myt5server:~#
root-myt5server:~# ldm list

Reduce control domain's resources as per its requirement....

Currently there are no virtual services under my control domain.

Let us add virtual services starting with virtual switch (vsw).

Virtual switch service and LDom are missing
Usage:
        ldm add-vsw [-q] [default-vlan-id=<vid>] [pvid=<pvid>]
                [vid=<vid1,vid2,...>] [mac-addr=<num>] [net-dev=<device>]

Next we need a vcc to provide virtual console service to all our guest ldoms,
