Failback EMC Celerra Datamover

Received a call from a customer this evening regarding complete loss of access to their SAN.

The customer was running a virtual infrastructure and all their VMs were hosted on the SAN, naturally this wasn’t a good situation to be in.

After looking at the SAN it was apparent that the primary datamover had failed over resulting in loss of access to all the vSphere hosts.

Luckily this was a fairly straight forward situation to resolve.

The resolution was thus.

1. SSH to control station
2. “nas_server -list” to check whether there is a datamover failover.
3. “/nas/sbin/getreason” to check the status of the datamovers. The 2 datamovers should be both in “contacted” status.
4. “server_standby server_2 –restore mover” to failback the datamover.
5. Run “/nas/sbin/getreason” several minutes later to make sure both datamovers are in contacted status.

Move Office 2010 MSOCache to Alternate Drive

I use a 60GB SSD as my primary boot drive on my dekstop and was looking at how I could free up as much space as possible.

I ran Tree Size and noticed that the MSOCache for Office 2010 was 1.2GB.
This is a hidden folder located in C:\MSOCache

I wanted to move this to my D: drive to free up the valuable space from my SSD but after some reading I found it is not possible to move the location of this using office install.

This is where Junction came to my resuce

Junction is a free utility from sysinternals and is availble from http://technet.microsoft.com/en-us/sysinternals/bb896768

Firstly I move the MSOCache using RoboCopy to my D: drive using the follwing command

Robocopy C:\MSOCache D:\MSOCache /MIR

Be sure to run the above as an elevated command prompt.

Using the /MIR switch mirrors the folder contents, security & attributes so the folder remains hidden on the D: drive

After Robocopy ran I deleted the MSOCache folder from the C drive.

The last piece was to create a junction point that links C:\MSOCache to D:\MSOCache and gives the 1.2GB back to my SSD

I downloaded junction and copied the contents to %windir%\system32 and then ran the following

Junction C:\MSOCache D:\MSOCache
