Rescan disks of P400

Hi All

I have read that if I want to rescan the disks of my P400 controller I shall issue:

echo "rescan" > /proc/driver/cciss/cciss0/1

If I do that (root) I get:
echo "rescan" > /proc/driver/cciss/cciss0/1
-bash: /proc/driver/cciss/cciss0/1: Not a directory

What am I doing wrong ?
Appreciate your comments on this.

Thanks

Re: Rescan disks of P400

/proc/driver/cciss/cciss0 is not a directory but a file, so /proc/driver/cciss/cciss0/1 does not exist.

Apparently the useless extra directory level has been removed at some point.

Try this instead:

echo "rescan" > /proc/driver/cciss/cciss0

Re: Rescan disks of P400

Thanks for your answer Matti,

If I do what you suggest I the following:
[root@kmsrv83 ~]# echo "rescan" > /proc/driver/cciss/cciss0
-bash: echo: write error: Invalid argument

I have a colleague who claims there is a bug involved. But I can not find any info about that. if you have any other suggestions I appreciate it.

Thanks

Re: Rescan disks of P400

I found this in the RedHat Knowledge Base:

http://kbase.redhat.com/faq/docs/DOC-7833

It is nominally listed for RHEL 4, but might be applicable for RHEL 5 too, as I don't know of any big changes in the cciss driver between RHEL 4 and RHEL 5.

Hi,

if youd do have the the HP Array Configuration Client Utlity (hpacucli), try installing it from HP on your system.
