raidctl on SUN T5240
Setting up a T5240 with two disks c1t0d0 and c1t1d0.

I am trying to use raidctl but when I issue.
Code:
raidctl -l

I get
Code:
Controller 1
    Disk: 0.0.0
    Disk: 0.1.0

So I try
Code:
raidctl -c '0.0.0 0.1.0' -r 1 1

and I get "Array in use."

I try
Code:
raidctl -c c1t0d0 c1t1d0

and I get "Array in use."

Does someone know what to do here? ThanksSmilie

you have booted from c0t0d0? if so, you can't use raidctl on this disk cause it is already in use. you have to boot from cd/dvd and setup the raid BEFORE the os installation!

ok, that is what I thought.

Solaris 10 is a 10G DVD, but download server is down currently.

OpenSolaris has a 686 MB CD iso I could use to boot off.

The T5240 has two 146GB Disks and 32GB FBDIMM memory.

The two disks on T5240 will just run OS, all applications will be
installed in zpool on a StorageTek Array.

What would be the recommendation for format and partition
of root, swap, etc... on T5240?

Solaris 10 7/08 version has the same problem in that case, boot from that older version of Solaris 10 in single user mode and copy the binary of raidctl to replace the existing one. It will solve your problem also.

Ok, this is what I did using new raidctl

In new raidctl you have to use raidctl -l volumename now and not just
raidctl

ok> boot cdrom -s

#raidctl -c -r 1 c1t0d0 c1t1d0

#format

at prompt format>
format c1t0d0 (it appears as one drive)
Auto Config
label

now you have to install OS, this is a must.

ok> boot cdrom - nowin

That is it.

I will post sun docs below if someone needs.

Solution  203544 :   Labeling volumes and drives when working with Sun Fire[TM] T2000 RAID  

Related Categories

    * Home>Product>Systems>Servers
       


Description

JYBFU5F Internal ID use only.


After creating or deleting a RAID volume on the Sun Fire[TM] T2000 server, steps need to be taken to properly label the newly created volume or the available drives (used in the RAID volume) so that Solaris[TM] may use them correctly.

Steps to Follow

NA8WC3F Internal ID use only.


After using the 'raidctl' command to create a RAID volume on the T2000 the user needs to ensure that steps are taken to label the volume properly for use by Solaris. The 'raidctl' command will create the volume, but it does not create a new label for this volume so Solaris will not see the correct information until this step is taken.

here is an example of creating and labeling a striped RAID volume:
----------

root@t2000 # raidctl -c -r 0 c3t1d0 c3t2d0 c3t3d0
Creating RAID volume c3t1d0 will destroy all data on member disks, proceed (yes/no)? yes

As you can see the volume c3t1d0 still displays the label of the 72GB disk even though it is now a striped RAID volume of ~204 GB. It needs to be labeled correctly by using the 'type' and 'label' options in the format utility.

First, eelect the 'type' command at the 'format>' prompt, then select 0 (zero) to auto configure the volume:
----------

----------
Now, after the label has been fixed, the volume will be properly recognized by the format utility.

The same needs to be done after deleting a volume for Solaris to properly recognize the newly available disks that were previously used by the RAID volume. Before correcting the label, you may see messages like this indicating the label is not correct:
----------

WARNING: /pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/sd@1,0 (sd4):
        Corrupt label - bad geometry 

        Label says 428854496 blocks; Drive says 143374738 blocks

----------
These messages will be not be seen after the label is corrected. Here is an example of the deletion of a volume and creating a proper label afterwards:
----------
