VTrak E-Class Product Manual
354
With other Promise VTraks, I used a server’s IP address in WebPAM PRO to
connect with the RAID subsystem. Why is this VTrak E-Class different?
VTrak E-Class has the server software embedded. With the E-Class, you
point your browser directly to the VTrak subsystem. WebPAM PROe is pre-
installed on the VTrak and launches automatically.
I can access the VTrak over my company’s intranet. But I can’t access it
from an outside Internet connection. How do I make the Internet connection
work?
This condition is not related to VTrak, but is due to your firewall and network
connection protocol. Contact your MIS Administrator.
Why can a RAID 1 logical drive on VTrak consist of only two disk drives?
On VTrak, RAID 1 logical drives work in mirrored physical drive pairs. You
could create up to eight RAID 1 logical drives. Or you can create a single
RAID 1E or RAID 10 logical drive with data mirroring and up to 16 physical
drives.
See “Installing Disk Drives” on page 15 and “Introduction to RAID” on
page 273 for more information on the number of physical drives you can use
for each RAID level.
Are logical drives on VTrak limited to 2 TB?
No. But verify that your operating system supports logical drives over 2 TB.
Also, for the operating system to recognize the full capacity of logical drives
over 2 TB, you must specify a sector size of 1 KB or larger when you create
the logical drive. See “Choosing Sector Size” on page 287 or more
information.
How can I be sure everything is working OK on the VTrak?
Locally: The VTrak enclosure has LEDs on the front to monitor the status of
power, field replaceable units (FRUs) and logical drives. When these are
green, VTrak is functioning normally.
Remotely: Check the Tree Icons in WebPAM. If there are no yellow or red
warning icons displayed, VTrak is functioning normally.
Can VTrak run using just one power supply?
Yes, it is possible to run VTrak on a single power supply. There are
redundant power supplies so that VTrak can continue running if one of them
fails. But deliberately leaving one power supply off negates this advantage.
In addition, leaving one power supply off reduces air flow through the VTrak
enclosure and can contribute to overheating. Always switch on both power
supplies.
