Raid 5 Questions
I've recently been tasked to configure a DS20 as a raid 5. I'm very new to tru64 but pretty experienced in Solaris and Liunx so bare with me.
Can someone point me in the right direction on accomplishing this. Listed below is my setup.
DS20 running Tru64 V5.1A with internal 1 18.gb drive(OS installed on)
Storageworks 4254R(DS-SSL14-Rm) with 6 36.4GB drives (What I want to raid 5 for /data)
DS-KZPCC-XE LVD Raid Controller.
when I view the diskarray in sysman it shows the entire disk being 138929.500MB Should it show 218GB 36.4 x 6 =218GB
Like I said above basically need helpfull information to get me started.
Thanks

Re: Raid 5 Questions
In a raidset you always lose the equivalent of 1 drive for storing parity data, so
that should give you 5x 36,4=182GB.
The 139 GB you see is less than 4 drives, unless maybe a spare drive for auto-replacement is defined.
Didn't you get a StorageWorks Array SWCCAgent kit with the KZPCC ?
Did you run the config utility from console mode ?
>>> run bios pza0

Re: Raid 5 Questions
Thanks for the reply. This system has been laying around the lab for about 2-3 years now, I'm not the original admin for this box so the person who initially set the system up threw all the media around the building so I guess I have to track down the SWCCAgent. Is there a way to see if the agent is installed??
When you say console mode do u mean the boot prom?? If so i haven't run that command
As far as finding out why I only see 139GB will this utility help me track this down?? Any other info would be great
Thanks
Jay

Re: Raid 5 Questions
# setld -i | grep -i swc
then
# setld -i
to view the file locations.
But you need to install additional software installed on a Win platform that can talk to the tru64 server, to be able to use it while online.
To configure it offline you need to #shutdown -h now
Then run the SMOR utility from the >>> boot prompt.
This link might help:
http://h18006.www1.hp.com/alphaserver/products/storage/kzpcc_ac.html
Q6: Is there a command line interface for KZPCC (like the RCU for KZPAC)?
A6: No. We have Alpha SMOR (via the console) for an off-line configuration utility and the SWCC for an on-line configuration utility.
Was a while ago, so that's about all I remember.

Re: Raid 5 Questions
If it doesn't show there, it won't show in your OS hwmgr database and you may need to verify that this device is supported on the KZPCC.

Only 9.1 to 72 GB DISK drives
(Ultra2 speed 10k rpm) are supported, no tapedrives in the table.

Re: Raid 5 Questions
The tape, you see there, is one that has been removed in the past, it has no valid path nor any special device files associated.
The command "hwmgr sho scsi -full -id 65"
will show you the details.
