New RP7410 7100 disk array

Jeff Hagstrom — Tue, 26 Oct 2004 15:31:22 GMT

We just got a new box(RP7410), it has 15 18 gig drives and 2 18 gig internal drives. It is running 11.11. VG00 is configured on 1 of the internal drives, however we can not see any of the other drives. Is there a special way to configure them so that the system will see them. The ioscan -f only shows 1 18 gig drive.

Is the disk array a VA7100 disk array? If so, then you will have to set the array up and create LUNs on the array of whatever size you need.

If it is not a VA7100 disk array, more information is required (like the specific disk subsystem typ) before I can give a suitable answer.

It is a 7100 array. How do you setup the arrays? And what are the LUNs?

Hi there,

Check your SCSI controllers first. Are they all visible?

$ ioscan -fC ext_bus

Next, do an ioscan -fH and check the output.

In addition to everything else, you should have gotten some software called Command View. This will need to be installed on the rp7410.

In addition, you should have gotten some documentation with the VA7100. I suggest you read it. It should explain how the array works, how to set up LUNs and all that fun stuff.

If you don't have the VA7100 docs, here is a link to them:

The "setup, install, configure" section is a good place to start.

It sounds like you have some sort of array for the external drives. It would be nice to identify the array. Unless you are using JBOD's (Just a Bunch Of Disks), you must configure LUN's on the array. The LUN's (which might be comprised of many physical disks) are what the host computer "see's" rather than the individual physical disks.
Without knowing the specific hardware, it's not possible to walk you through the LUN creation (e.g. if may be from the array front panel).

With command view you set up LUNs or arbitrary size. There are no LUNs until you create them as this is a virtual array. I suggest that you read the product description on the web page.http://www.hp.com/products1/storage/products/disk_arrays/midrange/va7100/index.html
