Raid Manager 6.22 and A1000 config

Raid Manager 6.22 and A1000 config

Config and setup

Firstly install the Raid manager 6.22 (6.221) software on the Solaris 8 system.

 # pkgadd -d . SUNWosar SUNWosafw SUNWosamn SUNWosau  
Defending upon your raid manager version and  scsi/fibre card type 
you will need to patch the system. 
The following patches are recommended for Solaris 8.  

Solaris 8 & Raid manager 6.22108553-07
108982-09
111085-02
Solaris 8 & Raid manager 6.221112125-01
108982-09
111085-02
Ultra 60106455-09
Fibre channel card109571-02
It is probably worth giving the system a reconfigure reboot at this stage.

Firmware

The first thing to do is check the firmware of the A1000. This can be done with the raidutil command. ( I assume the A1000 is on controller 1. If not then change the controller as appropriate.

 # raidutil -c c1t0d0 -i  
If the returned values are less that those shown below 
you will have to upgrade the firmware using fwutil.   
Product  Revision  0301  
Boot Level        03.01.03.04  
Boot Level Date   07/06/00  
Firmware Level    03.01.03.60  
Firmware Date     06/30/00  
To upgrade the firmware perform the following.   
# cd /usr/lib/osa/fw  
# fwutil 02050632.bwd c1t0d0  
# fwutil 02050632.apd  c1t0d0  
# fwutil 03010233.bwd  c1t0d0  
# fwutil 03010235.apd  c1t0d0  
# fwutil 03010304.bwd  c1t0d0  
# fwutil 03010360.apd  c1t0d0  
You can now re-perform the "raidutil -c c1todo -i" command again to verify the firmware changes.

Clean up the array

I am assuming that the array is free for full use by ourselves and intend to remove any old luns that might be lying around.

 # raidutil -c c1t0d0 -X 
The above command resets the array internals. 
We can now remove any old lun's.  
To do this run "raidutil -c c1t0d0 -i" and note any luns that are configured.  
To delete the luns perform the following command.  
# raidutil -c c1t0d0 -i    
LUNs found on c1t0d0.     
LUN 0    RAID 1    10 MB     
Vendor ID         Symbios    
ProductID         StorEDGE A1000    
Product Revision  0301    
Boot Level        03.01.03.04    
Boot Level Date   07/06/00    
Firmware Level    03.01.03.60    
Firmware Date     06/30/00    
raidutil succeeded!   
# raidutil -c c1t0d0 -D 0 
In the above example we are removing lun 0.  
repeat this command changing the lun number as appropriate.  
We can now give the array a name of our choice. (Do not use a .)  
# storutil -c c1t0d0 -n "dragon_array"

Creating Lun's

The disks are labelled on the front of the A1000 as controller number and disk number seperated by a comma eg. 1,0 1,2 and 2,0 etc, etc. We refer to the disks without using the comma. So the first disk on controller 1 is disk 10 and the 3rd disk on controller 2 is disk 23. we will use disks on both controllers when creating the mirrors. I am starting with the disks on each controller as viewed form the left. The next stage is to create the luns we require. In the below example I will configure a fully populated (12 disks) system which has 18Gb drives into the following sizes. Here we will use the raidutil command again.

 # raidutil -c controller -n lun_number -l  raid_type  -s  size  -g  disk_list  
LUN 0   Size 8617mb of a stripped/mirror configuration across half of the first two disks.   
# raidutil -c c1t0d0 -n 0 -l 1+0 -s 8617 -g 10,20  
LUN 1   Size 8617mb of a stripped/mirror configuration across the second half of the first two disks.   
# raidutil -c c1t0d0 -n 1 -l 1+0 -s 8617 -g 10,20  
LUN 2   Size 8617mb of a stripped/mirror configuration across half of the next two disks.   
# raidutil -c c1t0d0 -n 2 -l 1+0 -s 8617 -g 11,21  
LUN 3   Size 8617mb of a stripped/mirror configuration across the second half of the next two disks.   
# raidutil -c c1t0d0 -n 3 -l 1+0 -s 8617 -g 11,21  
LUN 4   Size 34468mb of a stripped/mirror configuration across the next four disks.   
# raidutil -c c1t0d0 -n 4 -l 1+0 -s 34468 -g 12,13,22,23  
LUN 5   Size 17234mb of a stripped/mirror configuration across the next two disks.   
# raidutil -c c1t0d0 -n 5 -l 1+0 -s 34468 -g 14,24  
LUN 6  Size 17234mb of a non mirror configuration on the next disk.   
# raidutil -c c1t0d0 -n 6 -l 0 -s 34468 -g 15  
This then leaves the disk 25 or disk 5 on the second controller free as a hot spare. 
to set up this disk as a hot spare run 
# raidutil -h 25

Finishing off

We are now ready to reboot the system performing a reconfigure. When this is done we can format, partition, newfs and mount the disks in the normal way.

Other commands

The following is a list of possibly useful raid manager commands

  • rm6 (GUI interface)
  • drivutil (drive / lun management)
  • healtchk (helth check on a raid module
  • lad (list array devices)
  • logutil (log formatting program)
  • nvutil (edit / modify NVSRAM)
  • parityck (parity checker and repair)
  • rdacutil (redundency controller for failed bits and load balancing)
  • storutil (host and naming info)
