Virtual Disks

Question

Hi people,

I'm working with CX4-480 and ESXi 4.0 (VCenter, SRM...).

Some LUNs named "virtual disks" appeared without any command issued by the storage administrators. I think there is something related with SRM.

I coulnd find anything at logs... any "bind" command.

These LUNs are all the same size (61,786 GB) and they are not assigned for any host.

I read some papers from EMC but I was useless.

Do you know about this?

Thanks.

I would do as AranH suggest and change the password on that account.  If they have to do something again, it will force them to contact you and then you will know when someone is messing around inside your array.

where do yo usee them ..in Navisphere , vSphere ?

tassia1 · Answer

Navisphere Manager, inside the RAID Groups.

AranH1 · Answer

Can you provide a screenshot of what you are seeing? It almost sounds like you are viewing the details of the VM related information available in Navisphere when the vCenter or ESX host information is imported into Navisphere.

AranH,

I can't insert the image here, There is a message saying the content is not allowed. I will try to reproduce here for you....

**Navisphere Manager**

RAID Group 28 [RAID 5; FC]

+-----Virtual Disk 8197 [146; RAID 5; FC]

+-----Virtual Disk 8202 [152; RAID 5; FC]

+-----Virtual Disk 8203 [153; RAID 5; FC]

Thin LUNs do not appear in RAID Groups, they are listed under the Thin Pool there were created in under the Storage Pool container.

To upload an image make sure the file extension is a lower case .jpg. Some Windows programs make the extension upper case and I have seen that cause the image upload to fail.

Thats what i see but according to the OP, no one created them.  They just showed up. Only thing i can think of is someone did it or a script was run....

kenn2347 · Answer

ok well we can see someone or something used the account SRM_Vmware to bind something.

Any scripts being used that call that user? I dont know enough of SRM to know if it has that functionality. which site is this in SRM? the protected or recover site?

kenn2347 · Answer

Those sure look user created.. do you have multiple array's in your environment? if so, maybe these should have been created on a different one and they had the array's mixed up?

I asked a person that is very familiar with SRM and they siad that SRM doesnt automatically create lun's on an array it is connected to

im curoius now....

I rescued some messages from logs.... Idon't konw if it is related bacause we are testing SRM.....

(4600)'Poll' called by ' Navi User SRM_Vmware' (10.5.0.113) on 'EV_ExpandableSubsystem' (Result: Success).

Bus 2 Enclosure 4 Disk 0(60a) Internal information only. A logical unit has been enabled[0x00] 1c02ba b4012c

(4600)'thinlun' called by ' Navi User SRM_Vmware' (10.5.0.113) with result: Success (Navisphere CLI command: )

tassia1 · Answer

The user 'SRM_Vmware' was created to SRM access the storage in a case os a disaster. It's an application. Both sites are being protected by SRM, but we could test only for the second site (the one who doesn't have the virtual disks), next week we going to test in primary site. Guys, I appreciate your help... I'm thinking in call the VmWare Engineer, it's better. Thansk you.

i am really curious now.... maybe you can filter the event logs for a 0x4600 events.  those point to the creation of lun's (thin or regular).  and see when and by whom created them...

AranH1 · Answer

So when someone created those LUNs under the RAID group pictured they gave them a user friendly name of Virtual Disk XXX. The actual LUN number is what you see in the brackets.

Virtual Disks is a term used with thin luns. Are these thin LUNs?

tassia1 · Answer

Alias, We don't have licensed Virtual Provisioning (thin luns).
