Monitor the progress and completion status of the download to the enclosures. The
progress and status of each drive enclosure participating in the download is displayed in
the status field of the Select enclosures table. When the transfer is complete, you see the
window shown in Figure 7-20.

7.1.9 Updating the hard disk drives’ firmware
Updating the hard disk drives’ firmware is sometimes required after upgrading the ESM
firmware or the controller firmware/NVSRAM. Always refer to the readme file associated with
the hard drive and ESM firmware upgrade package for precise instructions.
Parallel drive firmware download
Storage Manager allows you to download hard disk drive firmware to several drives in
parallel. This way, large configurations with multiple expansion enclosures are not affected by
the download time that updating a large amount of drives might generate.
You can update up to four different drive types simultaneously. It does not matter whether
there are different types or different firmware versions.
Note: All I/O has to be stopped while downloading the firmware to the drives.
In the DS5000 storage subsystems with the FC/SATA intermix premium feature enabled,
do not download the drive firmware to both SATA-technology hard drives and Fibre
Channel technology hard drives at the same time. Complete the drive firmware download
to all of the drives of a drive technology (either SATA or FC) before downloading the drive
firmware to the drives of the other drive technology (either FC or SATA).
