Dynamically increase disk size of SQL server on EVA4400

[John821]

Hi,
We have an EVA4400. We have SQL server connected to a LUN on the EVA4400. Is it possible to increase the size of the LUN without brining SQL server down?
Thanks

Well, as long as it is not some strange partition setup, it should work fine.

- Increase the size of the virtual disk.
- Rescan in Disk Administration.
- Use DISKPART to extend the partition table and the filesystem:

this should work, you can search thru windows re the diskpart steps,but as best practice,please do back the DB before doing the capacity expansion

Hello,
did the seme many times with Eva6000 and SQL 2000-2008 under win2003/2008.
Do the steps described above with one more advice - IF your system is under heavy I/O load, STOP temporary SQL before disk extend under windows. It will be really fast then (1-5 seconds). If you do not stop SQL, it could take much more time and nerves... :)
