Extending the logical drive on SSD storage blade.

[Narendra Uttekar]

Hi,

We are running out of space on SSD storage blade...So i thought to remove the spare drive allocated and add that to existing logical drive 0 or create new logical drive 1 but is it possible to create new logical drive with one drive? Or i remove the spare drive and extend the current logical drive 0 from 5 to 6 disks. If that is possible then the data on existing volume will remain as is or will have any problem? And also if i extend the current logical drive 0 from 5 to 6 disks whether it will automatically increase the PE size for LUN i.e. /dev/disk/disk40?

Is the commands below are correct to remove the spare drive and add drive to existing logical drive 0?

saconfig /dev/ciss12 –D 0 –s 1I:6

saconfig /dev/ciss12 –E 0 –p 1I:6
