Installing a Second RAID Controller
361
New Settings for Dual Controllers
With the second controller successfully installed, make the following settings:
• Redundancy Type – Set to Active-Active or Active-Standby.
See “Making Subsystem Settings” on page 60 or page 162.
• LUN Affinity – If you choose Active-Active redundancy.
See “Making Controller Settings” on page 70 or page 167.
Dual Controllers and SATA Drives
If your VTrak subsystem has SATA disk drives installed, you must install a SAS-
to-SATA adapter on each of the SATA drives.
Without the SAS-to-SATA adapter, SATA drives display a red X icon and Not
Usable status.
Obtain SAS-to-SATA adapters from PROMISE Technology at
http://www.promise.com.
SAS drives do not require adapters.
Also see “Installing Disk Drives” on page 15 and “Contacting Technical Support”
on page 351.
Note
The VTrak subsystem boots its RAID controllers sequentially. With
a second controller installed, your subsystem takes about a
minute longer to boot. This condition is normal.
