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.

Few days back i moved a user from its OU (OU1) which was synchronizing with Office 365 to another OU (OU2) which was not synchronizing with Office 365.

(1) was unable to receive email but can sent emails, mails for this user were stuck in Queue
(2) in Office 365 admin Center getting errors when checking its properties, which was as below.

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.
