It’s simple to debrand an “OEM”ed variant of the Dell PowerEdge R740 or R640 based “appliance”. First you will need the default identity which can be found here: DELL PowerEdge OEMR XL Dell Branded ID Module with Windows Embedded OS Support You’re looking for the 4XHVW_14G_DBE_CustBSU_3_00.exe (local mirror) file which must be extracted first prior…
A host side migration between arrays can be a nerve racking task especially when you come across issues. Data loss is a constant fear in the back of your mind and what is your fail-back plan should you need to execute it. During a PowerPath migration, I learned the hard way that a host side […]

After a disk has faulted, the disk goes into a transitioning or an equalizing state. EMC uses different terminology to describe the action of repairing a faulted disk. Transitioning or equalizing times can vary based on the type and speed of the disk but your SAN utilization will have a direct impact on how fast […]
Quest (Vintela) Authentication Services (VASD) provides schema extensions to Active Directory to authentication against LDAP by providing SID to UID/GID mappings and vice versa. In multiprotocol environments that provide NFS and SMB protocols to the same underlying data it becomes tricky with permissions and file ownership since it must be maintained in the *nix and […]
If you ever have a need to get into an EMC DataDomain BIOS screen the default password is a simple pattern based off the major series model number. For example: DD460 = d400d (delta four zero zero delta) DD670 = d600d (delta six zero zero delta) DD880 = d800d (delta four zero zero delta) The pattern is simple, “d […]
During testing, the EMC Isilon storage was successfully reading the Active Directory Attributes but the data was incorrect. The data that was in the uid & gid fields were id’s that were automatically generated by the Isilon storage itself. The id’s that were generated by the Isilon storage took precedence over any mappings that were […]
There are many challenges that are faced when an organization is forced to run a mixed protocol environment to serve up the same data. This introduces additional management tasks and additional complexities. In a mixed protocol environment you must manage Windows Access Control Lists (ACL) to enforce Windows permissions in addition to managing *nix user/group […]

Login using the ‘sysadmin’ user account and password. 3. Scroll down to […]
Here is a list of good commands that I use frequently when working with an EMC SAN, in particular, a Celerra or VNX series. Enjoy! Summary: Gets the disk information, state and other metrics. Note: that 1_1_14 is Bus 1 Enclosure 1 Disk 14. Command: Result: Summary: Get all LUNs that are trespassed (not on […]
