Upgrading The HDD

Dears,
currently I have hot plug-play 2*146(10K) with RAID1 configured, I like to change 146 HDDs (10k) to 146(15K), how can I replace the HDD, how it will rebuild the data? How much time it takes? & how I replace the HDD, offline or online?
Thanks

hi,

1, its depend if your raid is HW or SW ( OS level based )

2, how much time is depends on point 1, and the system performance.

Re: Upgrading The HDD

If you have a smartarray controller replacing the drives one at a time should be no problem. Done it manny times.
Rebuild should probably take around half an hour but this depents on the rebuild priority setting of the raid controller and on the system load. Offline is usually faster since there is no os running.
