Pinned topic HDD Update Downtime

‏2011-10-04T09:12:24Z |
We are planning a HDD update on our DS3400 and learned there is a downtime for it (installation and setup guide copy-pasted below)

2.1 Ensure that all activities to the controllers is stopped while

performing hard disk drive (HDD) firmware updates with all levels

of controller firmware.

The DS3000 storage subsystems can update all drives in a

configuration for up to four different drive types at the same time.
For DS Storage Manager Client version 2.x or 10.x, perform the

following steps to download hard disk drive firmware:
+ NOTE: Updating hard disk drive firmware for either ST31000424SS or+

+ ST32000444SS requires that firmware version BE51 be downloaded to+

+ the hard disk drives prior to upgrading to firmware version BC26.+
a. THE DRIVE FIRMWARE UPDATE WILL REQUIRE DOWNTIME. When

updating drive firmware ensure that no HOST I/O is being

sent to the DS3000 controllers.
b. Open the Subsystem Management window.

c. Click Advanced => Maintenance => Download => Drive Firmware.

Follow the online instructions.

I want to know how long this downtime usually takes. I think this is a crucial information left out.
Thanks.

    It takes approximately 4-5 minutes per drive, but you can upgrade multiple drives in parallel. Just make sure there is no host IO when the hard disk firmware upgrade is being done.

    Yujinn,

    Where do you get the BE51 firmware for the ST31000424SS drives?? I can't find it anywhere on IBMs site or online.

    Thanks!!
