Solaris RAID0 doubt...

Suppose I am typing metastat command and it is showing:

d100: Concat/Stripe
    Size: 369495 blocks (180 MB)
    Stripe 0: (interlace: 32 blocks)
        Device   Start Block  Dbase     Reloc
        c1d0s0      16065     Yes       Yes
        c1d0s1          0     No        Yes

I wish to know how do I know which method of RAID 0 it is ( concatenated or stripe)???

Is there any specific way to distinguish between concatenated and striped volumes of RAID 0 through some command?

To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

for me , the most easy is with command "metastat -p"

for example one one metadevice type "concat" of three components appear

d50 3 1 c5t0d0s0 c5t1d0s0 c5t2d0s0

however one metadevice type "stripe" appear

d50 1 3 c5t0d0s0 c5t1d0s0 c5t2d0s0 -i 32b

Note the diference in the order in the digits after of the metadevice name, additionally, one "stripe" metadevice include "-i" option, thats mean the interlace size for the read/write operation in the Stripe device.

I hope that this be useful
