random thoughts at best
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 […]
For retro purposes, I wanted to make an old instance of YaBB SE 1.5.4 a read-only version to look back with friends to get some kicks and laughs. I first upgraded from YaBB SE 1.5.4 to YaBB SE 1.5.5c. This was a small project try bring this up on a modern operating system, primarily around the […]
EMC Avamar Error 10007 is an interesting error with a little history behind it. After opening up a support case with EMC, they indicated that error 10007, vmx file is suspiciously small, is a legacy error message from the VMware vCenter 4.x version of vCenter. From what the support technician said, is that the VMX […]
“A general system error occurred: Failed to start migration pre-copy. Error 0xbad003f. Connection closed by remote host, possibly due to timeout.” “A general system error occurred: Failed to start migration pre-copy. Error 0xbad004b. Connection reset by peer.” Another issue, that I recently came across was a live vMotion issue where the vMotion migration would fail […]
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 […]
A mixed protocol environment means that you have two means of accessing the same data generally through SMB/CIFS/Samba and NFS. SMB is natively supported in Windows and NFS is natively in *nix environments. There are complexities an organization will always run into when running in a mixed protocol environment which is a result of how […]
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 […]
