Configuring Raid; Raid0/Striped; Raid1/Mirrored; Upgrading Firmware - HP AJ878A - StorageWorks 320 GB Hard Drive User Manual

• Add an entry similar to the following to that file:
types = [ "fio", 4 ]
The parameter "4" represents the maximum number of partitions supported by the drive. For the IO
Accelerator, this can be any number from 1 upwards. Do NOT set this parameter to 0.

Configuring RAID

You can configure two or more ioDrives into a RAID array using standard Linux procedures.
NOTE:
If you are using RAID1 mirroring and one device fails, be sure to run a fio-format on the replacement
device (not the existing good device) before rebuilding the RAID.

RAID0/Striped

Enter the command:
$ mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/fioa /dev/fiob
to create a striped set where fioa and fiob are the two IO Accelerators you want to stripe. (Use
fio-status to view your specific names.)

RAID1/Mirrored

Enter the command:
$ mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/fioa /dev/fiob
to create a mirrored set using the two IO Accelerators fioa and fiob. (Again, use fio-status to view
your specific names.)

Upgrading firmware

WARNING!
It is extremely important that the power not be turned off during a firmware upgrade, as this could
cause device failure. If one is not already in place, consider adding a UPS to the system prior to
performing a firmware upgrade.
