Installing a Second RAID Controller
447
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 77 or page 211.
• LUN Affinity – If you choose Active-Active redundancy.
See “Making Controller Settings” on page 86 or page 216.
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 435.
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.
