problem by put new disc on eva 4400

Hi,

 

I put new disk of 600gb 10k on existing diskgroup with disc of 400gb 10k, and the issue that appear me is when i click in the part where say the different sizes using different raid,( for example raid 0 1234gb  raid 1 244gb raid 5 1832gb,) and something curious happend, after putting 8 new disc of 600gb 10k in this diskgroup appear me the same capacity with all raids.

 

i dont know if i explain well, but somebody knows why happened this, and how can i fix it

 

thanks a lot

Re: problem by put new disc on eva 4400

A protection level of single reserves the space of 2 of the larges disks per disk group, protection level doubles reserves the space of 4 times the largest disk.

If you have let's say 500GB disks and double protection, you have a reserved space of 4x 500GB. If you add now a single 1 TB disk, the reserved space will increase to 4x 1TB, so you will have less space available than before.

I hope this answers your question.

Hope this helps!

Torsten.

Thank you Torsten, I know this behavior with the type of protection
The thing is when i see the capacity that is available on different level of raid i see the same capacity for all levels of raid, you know what i mean, althougth i have put disks of 600 gb, it have to appear different space available for different levels of raid

This sometimes happens, the controller need a re-sync. Consider to reboot the controllers one by one first. If this does not help, there is also a special procedure for a controller resync.

Hope this helps!
