Checking the health of your 3ware® RAID array

With 3ware, you can use a browser interface to check the health of your bare metal server. However, unless you access the interface locally, by using a browser is a security risk. Use the command-line interface instead.

Quick command reference for 3ware® CLI tools

These devices must be followed by a number that identifies which devices are being queried.

tw_cli /c0 show (Output shows information that is needed to know the health of the RAID array)

./tw_cli /c1 show

Example:

Unit  UnitType  Status         %Cmpl  Stripe  Size(GB)  Cache  AVerify  IgnECC

------------------------------------------------------------------------------

u0    RAID-5    OK             -      64 K     465.641   OFF    OFF      OFF

Port   Status           Unit   Size        Blocks        Serial

---------------------------------------------------------------

p0     OK               u0     233.76 GB   490234752     WD-WCANY1727093

p1     OK               u0     233.76 GB   490234752     WD-WCANY1622544

p2     OK               u0     233.76 GB   490234752     WD-WCANY1657267

p3     NOT-PRESENT      -      -           -             -

Quick reference notes:

c = controller (Controller can be 0 or 1)

u = unit (Unit number depends on number arrays. It is 0 in most cases.)

p = port (Port denotes port number. In most cases, it is 0-4.)
