Question about mounted Hardware

Daniel Schneider_3 — Mon, 22 Nov 2004 04:17:42 GMT

Hello all,

I have a discussion with a Sysadmin, about what Disks are insertet in a Server.
It is a HP N4000 (RP7400) with 4 Processors and a lot of Disks. So attached you can see the output of ioscan -fn.
Can anyone tell me please, how many 36Gb disks and how many 73Gb disks are mounted to that server?

Thanks for any Help
Daniel

Hi Daniel,
You seem to have 6 disks of 36GB and 2 of 73:
The 12 36GB are in fact 2* 6 disks but seen twice by 2 different FC controllers, the same applies to you 73GB.
so disk c4t0d0 and c6t0d0 are the same disks but accessed by 2 separate paths (alternate) for redonduncy / load balancing... (There are times when you have to upgrade some microcode on the SAN...) that when your are happy to have alternate paths...

All the best
Victor

hi,

as per ioscan output you are having 6*36 gb disks 2*73gb disks which is accessed through
two fc cards /dev/td0 fcp 0 0/12/0/0.8 fcp and
/dev/td1 fcp 1 1/12/0/0.8 fcp.
