Storage drive appearing as RAW in Windows Server 2008 R2

I faced an issue that a storage drive assigned from DS 3400 was appearing in RAW format.
i was unable to open it, initialize it and it asking every time to format it. as it was not in NTFS format and Windows was unable to open it, RAW format was unknown for it.

Actually the was that, the server was restarted and the IQN was changed of the server due to some issue.
after putting the IQN again in Storage issue was resolved.

The IQN of a server you can find as below.
Open ISCSI initiator and then go to Favorite Targets and there you will see the IQN.

The IQN you will put in below path on the DS3400 storage.
Open DS3400 storage console (i have IBM DS storage Manager 10)--> here you have to open the required storage, -->Host Mappings Tab-->select the required host group--->right click on Drive and select-->select Manage host port Identifiers-->Add Host port identifier information (This value and the value on server should be the same)


P.S: possibility of this is

if you rename the server.
if you change the IP.
if there is network device between SAN and Server which malfunction.

The UMMailboxPolicy policy assigned to the mailbox in the source forest couldn‎'t be mapped to the policy in the target forest

I have hybrid environment with Exchange server 2013 and office 365. i was trying to migrate a mailbox from on premises to office 365. but was getting the following error and migration was failing.
the reason was that the user was enabled for UM and a UM policy was applying on it, which was not exist in office 365. so as a work around i just went to exchange control panel, search this user mailbox and disable the Unified Messaging in Phone and Voice Features, in mailbox feature of this user.
then tried to migrate again and was able to migrate this time.

My issues

1. WSUS was not stable, it crashed again after few minutes
2. WSUS administration console did not connect
3.  In SCCM console the status of Software update point was not healthy

After searching enough i got the following link (https://blogs.technet.microsoft.com/wsus/2016/05/05/the-long-term-fix-for-kb3148812-issues/)
which is relevant to this issue but in my case KB3148812 was not installed and the KB3159706 was installed.
Now to resolve this issue i took the following steps

2. Uninstalling KB3159706
3. Restarting the server

Lync Server Front-End service not starting

Today I faced an issue, my Lync server 2010 internal certificate got expired then I have to renew it.
My environment is
I have two FE servers, one Archiving/Monitoring server and one LyncEdge server.
The expired certificate was default certificate of  Lync Front end fool.

Now to renew it I generate CSR on first FE server, I added all the required subject alternate name but lost one (second FE server FQDN),  and get SSL against this CSR from my internal CA.
I download the SSL form CA and copy to first FE server, import it and assign to the service according.
after that I start the "Lync Server Front-End" and it was started without any issue.

Now for second FE server I export form first FE server and import in second FE server and assign as well with out any issue. Then I went to services on this server and tried to start the "Lync Server Front-End" service but was unable to start and was getting the following error in event viewer as well.

Event ID: 14587
Lync Server machine FQDN cannot be located in the default certificate.
Machine FQDN: 'FE02.mydomain.com
Cause: This is a configuration problem.
Resolution:
Make sure the default certificate matches the machine FQDN.

Now start thinking on error description and I decide, lets check FQDN of both servers in the subject alternative names of this renewed SSL.
after checking, it was found that the name of the second FE server was not included as Subject alternative name.
For it I started to renew again the SSL with the above mentioned method but just add the FQDN of the second FE server as well as Subject alternative name in CSR.

Now after adding the FQDN and assigning the new SSL to services on both FE servers I was able to start the "Lync Server Front-End" service without any issue on second FE server as wll.

and in this way my issue was resolved
