Solaris 9 - 3510 - sccli - recreating a concatenation

I haven't done much with metadb or Solstice DiskSuite (I guess now called "Solaris Volume Manager" ("SVM") )

I'm not even sure if I need to use them...

I have a StorEdge 3510 that has several disks in it. 3 disks are concatentated together as one drive. Well, one of the drives died in that concatenation, so I replaced the drive. Ofcourse, because there wasn't any fault tolerance, I lost all the data. So, what I want to do is simply recreate the concatenation with the 3 drives.

So, I need:

1. determine which 3 drives were used in the previous concat.
2. recreate this concat
3. format it - if needed, so I can dump some data to it.

I'm guessing that I don't even use the metadb or SVM, and I recreate this within the sccli tool.

Thanks for any input!

i dont know the sccli tool but

use metastat to find out what the components were

i.e.

metastat d10

then

metaclear d10

then

metainit d10 1 3 c1t0d0s2 c1t1d0s2 c1t2d0s2

(or whatever your three slices are)

after this

newfs /dev/md/rdsk/d10

and thats about it

The sccli tool is the 3510 StorEdge Array manager...

Hanno P.S.

if you use disk suite (or SVM) you should see a failed component:
# metastat
or
# metastat <mdev>
and a message explaining what to do to fix the problem (usually a "metareplace")

If you see something like "metareplace <mdev> <comp1> <comp2>" you may want to run
# metareplace -e <mdev> <comp1>
to have it use the same component as before (as you did replace it)

The sccli tool is the 3510 StorEdge Array manager...I believe.

So, I thought that the sccli tool would HAVE to be used to manage the disks inside the array.

Is that not the case?

Hanno P.S.

I doubt you use SDS (or LVM) as the 3510 has hardware RAID
Using sccli oyu may want to check your logical drive settings with
# sccli <device> show logical-drives
Everything else is left to using "sccli" to reconfigure the RAID

Ok...using you command, I get:

sccli> show logical-drives
LD LD-ID Size Assigned Type Disks Spare Failed Status
-------------------------------------------------------------------------
ld0 5F0AFF2E 204.35GB Primary RAID1 6 1 0 Good
ld1 2125D7FF 68.12GB Primary RAID1 2 1 0 Good
ld2 1A3AC015 204.35GB Primary RAID0 2 0 0 Incomplete

So, it looks like it's the ld2 that needs to be rebuilt...

The concatenation was using 3 disks...3 70GB disks, making it approximately 200 GB.

do you know what I need to do from here?

...and, from the looks at this command, it looks like 8,9,10 are the ones I need to concatenate.

10 looks likes its the failed disk, I replaced...breaking the 8,9,10 concatenation.

JustUNIX:

From the link you posted above, (under Resolution:)

I'm suppose to select "view and edit SCSI Drives" from the menu...

- go "view and edit SCSI Drives"

How do I get to the menu? There seems to be a program that brings up some kind of "menu"...what program (or executable) is it?

Hanno P.S.

check the tools that come with your RAID system. Try something like:
grep `sccli /var/sadm/install/contents | awk '{print $4]'` /var/sadm/install/contents

The meu is available in the 3510 itself (log on to the RAID box itself - is it connected to the network?)

"chapter 2" seems to suggest connecting to the array through a COM port.

I'm guess that, that will get me to that "menu" screen that I need to see.

#1 - will I have to bring the array completely down - just to connect with a terminal progam? Or, can I connect to it 'hot'?
#2 - Is this basically the only way to get to the array 'menu'? It sounds awefully inconvenient - other arrays I've configured allow you to manage it on the fly.

I see that I could also manage it through it's own IP address. I guess I could connect it to the net - but this brings me question, how do I assign an IP address to it - and do I use telnet to access it?

From my original question:

1. determine which 3 drives were used in the previous concat.
2. recreate this concat
3. format it - if needed, so I can dump some data to it.

Here are the steps I've taken to recreate the concatenation:

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

1. determine which 3 drives were used in the previous concat.

Connect to the 3510 array manager program:

The 3510 array has a COM port that must be connected to the server.
To connect to it via COM1, type:
tip -38400 /dev/ttya

To connect to it via COM2, type:
tip -38400 /dev/ttyb

Once connected, ctrl-l to refresh the display.

In the "view and edit scsi Drives", I could see the specific drive that was replaced. The "status" column wasn't ON-LINE like the other drives.

In the "view and edit Logical drives", the "status" of the logical set was INCOMPLETE. When selecting this set, I could see the exact 3 drives involved in making up the logical drive/concatenation.

2. recreate this concat

view and edit Host Luns: deleted the drives associated with the affected lun.
view and edit logical Volumes: deleted the Volume associated with the affected volume.
view and edit logical drives: deleted the logical drive associated with the affected drive.

Recreate the concatenation is reverse order:

view and edit logical drives
view and edit logical volumes
view and edit host luns...

3. format it - if needed, so I can dump some data to it.

newfs /dev/dsk/cXXXXXXX

where XXXXXXX is the specific controller/disk to prepare.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Some things to note:

You may have to power off the array, after replacing the disk. Then do a "scan" on it - to be recognized by the array.
