SolutionA.
1. make a full backup;
2. destry everyting on the 12h, pull out all drives and put new ones in;
3. format array, create new LUNs;
4. restore
B.
1. make a full backup;
2. turn rebuild priority to high;
3. for each disk, one by one:
- pull ONE 4GB disk at a time;
- insert one 18GB disk in;
- wait until rebuild/balancing will complete;
- check that 12h is healthy with 'arraydsp -a' command;
- proceed with next disk;
4. turn rebuild priority back to low
A is fast but depends on backup/restore speed and not online; B is slow, but can be done online, although hosts can experience increased delays accessing 12h

Re: Autoraid 12H upgrade
for 18G drives, you'll need to potentially change your fans. The 18G fan module has a plastic bubble over the fan icon, rather than the 7200rpm fan modules sticker label. Only 1 fan can be removed from the 12H at any one time.. and you've got 10mins or so before the array will shutdown due to fan removal.. ie insert the replacement soon after!
I am not certain if controller f/w needs to be upgraded to support the 18G drives, in either case if you've got HP56 up it'll certainly be okay.
Consider also changing rebuild priority, if a disk fails from now on, the rebuilds will take much longer with 18G drives......
Later,
Bill

Re: Autoraid 12H upgrade
Lower than 10krpm are the 7200rpm drives of capacities such as the 4G and 9G drives.
If your drives are 10krpm you do need new fans.
Good luck,
Bill

Re: Autoraid 12H upgrade
BTW, 36GB drive modules (all 10K RPM) are available as well.
I would go ahead and upgrade the firmware to HP62 - it's easy and you can do it yourself - and no data is lost.

Re: Autoraid 12H upgrade
You might try to find 36GB drives.
I would upgrade firmware to HP62; it's very easy to do and no data is lost.

Re: Autoraid 12H upgrade
read notice from that page I mentioned. You need to change fans in order to have 10K disks in. And nothing more. Then proceed with disk replacement

Is it an option for reseller to wipe drives?

Re: Autoraid 12H upgrade
I was wrong (better to note it later than never :o) ). Maybe meant one thing but wrote another. "As soon as balancing will finish" should be read as "As soon as REBUILD will finish".
I do not remember such data loss cases, but it's good practice not to 'touch' array until it will rebuild. When you insert drive into array hotplug event causes SCSI bus to be reset. Normally, when all devices are behaving well, firmware should handle it correctly, include new drive into the disk set and rebuild to newly installed disk.
I would follow this practice and waited for rebuild to complete, and then inserted all disks at once (in this case all the data will be rebuilt and have redundancy)
