LUN configuration

[BOB BARBA]

I have a rather basic question.

I have an FC60 configured on my N4000 system with three SC10 enclosures housed in it. I currently have 5 LUNs configured (each LUN comprises of three discs - one disc from each SC10). I have purchased three additional discs and plan to add one to each SC10 and then to configure these discs as a 6th LUN.

1. Can I use SAM to configure these discs or do I need to use other commands/software.

2. Do you have details of the steps involved.

I am comfortable with most of the standard LVM commands but have very little exposure to LUNs and specifically FC60 technology.

Any help will be gratefully received.

Many thanks ........ BobB

Bob,

To build a new LUN you need to use amcfg. Use amdsp to display all possible information about the array and disks in the SC10's.

amcfg -L : -d -r -S

=A or B
=6 in your case
= :
=RAID-level :-)
= The name assigned to the array.

Hope this helps

I think that FC60 configured as split-bus.

You can configure LUN through SAM but what I'm doing is via mstm or xstm that provides capability to perform common disk array management tasks and easy to use at the same time.
Binding LUN is very simple.
Just select three disks ( probably 2:2 4:2 6:2 ) sequentially, the type of RAID, LUN owner and stripe size something like that.

in mstm or xstm,
Select Tools -> EXPERT Tools -> RUN

Best regards,

There is one thing that you keep in mind.
Add disk to the disk enclosure step-by-step, which means that you put a disk module into the enclosure and wait for a few time, at least 1 minute, enough for the drive to spin-up and then insert another one.

It is possible to use SAM, if you don't want to type, or remember commands.

1) Install Disks
2) Bind LUN (in SAM select the following)
A) Disks & File Systems
B) Disk Devices Icon
C) Select Controller
i)Actions
ii) Disk Array Maintenance
iii) Bind LUN
D) Select Disks
i) LUN #
ii) RAID Level

3) Apply!

It could take up to 1 hour to bind a LUN of 18G drives!

SAM works just fine, once you see the management daemon running from ps -ef |grep AM60Server
