It's OK.

First replace broken disk, wait till SmartArray 5300 controller will complete rebuild (you can check rebuild progress in system management homepage, in Array configuration utility or just check messages in windows event viewer).
When rebuild completed replace second 9 Gb disk to 36 Gb disk and wait till rebuild completed. It's all. After this you even can create new logical disk on 36 - 9 = 27 Gb space.

You need to use diskpart tool
But you cannot extend C:\ partition with diskpart, only data volume.

However you always can create new logical disk on unallocated space.

If you use a 3rd party utility, you can extend the "C" (root drive). The utility I like is Partition Manager. Hope this helps.

Re: Change Hot Plug Disk with different size

After the the rebuild, you can use those utilities mentioned here to create 1 large C (root volume) and use disk manager (or diskpart) for the D drive. You can use what ever sizes you like. Let me know if you need anything else.

Hope this helps.

i'm very afraid
Another little question:
I read about id scsi
precisally with hot plug disk is not necessary to set (with the jumps) the id on the disk, is correct?
Thanks

Re: Change Hot Plug Disk with different size

Correct, not needed on these models. It's older clone desktops that people turn into servers and SCSI-1 devices.

Hope this helps and thank you for the points.

Re: Change Hot Plug Disk with different size

David,

>>is' it neccessary to update the smartarray firmware (Actual version for Smartarray 5302/64 is 1.28)?

YES. You use very old firmware version.
The most convenient way to update SmartArray firmware is online update - you run firmware update from windows and do restart:
http://h18004.www1.hp.com/support/files/storage/us/download/20193.html
Carefully read Prerequisites sections.

>>Is'it necessary update the firmware disk?

Generally speaking you need to use
Firmware Maintenance CD to update SCSI drives firmware.
http://h18000.www1.hp.com/support/files/server/us/download/23331.html
But in you case Firmware Maintenance CD doesn't contain firmware for you drives (check it here http://www.compaq.com/support/files/server/us/WebDoc/firmware/firmware740content.pdf)
I also didn't find firmware for drives you metion here http://h18004.www1.hp.com/support/files/storage/us/index.html
and in Options ROMPaq for SCSI Attached Drives (it contains firmware for old drives)
http://h18023.www1.hp.com/support/files/server/us/download/17149.html

So , I assume you new 36 Gb drive just have last firmware (no firmware updates appears for this drive). And regarding old 9 Gb drive - anyway you go to replace this drive ?

Re: Change Hot Plug Disk with different size

Dear Mike
Everythings ok
I updated Smartarray, Driver and firmware, changed the two disks and no data i lose
Perfectly!!!
Now how i can use the unused space?
I open the ACU utility and there is one Array A with 2 logical Drive:
8673 Mb Raid 1+0 and 52115 Mb Free Space.

Now how i can use the free space?
Can i expand the Array A?
The ACU Utility suggest to use the free space creating another Array.
I try Volume manager but i don't see the new free space!!!
Perhaps it's necessary to create another array for the free space and afther with Volume manager expand the existing partition to use it???

Waiting Best Reagard David

Re: Change Hot Plug Disk with different size

you can go into the array A and extend the new space in the ACU, it will give you a max number you can use, just type that number in I.E. 69432 then save config changes. once it's configured, now you can use the volume manager (partition manager) at the OS level to "extend" C to max size. Hope this helps.
