redhat can't see the rest of storage partition
I Have a problem with the storage,
I have four server's installed already redhat enterprise 4.5
and two of it can see the all partition storage and the another two see only sda
therefore, when i wrote "fdisk -u /dev/sdc" or even "fdisk /dev/sdc"
i see "Unable to read /dev/sdc"
therefore, mount the disk can't do it too,
So, can any one help me how can i solve that problem..
how can i let my server see that storage partition..?
plz check the picture on the following link,.
Ur support will be highly appreciated,
Little bro in linux:)
I suspect it's because it's raided. Is it software or hardware raid, because what you would need to check will be different.
But for sure its not a hardware, coz before i instal the redhat 4.5 it was working, & how the two server work fine &see all the partition,
therefore, i want to know how can let my redhat in the new two server see the rest of storage partition,
If u can teach me from the begining how to let redhat take the storage partition..?
Thanx in advance.
Well the reason I ask, is if it were hardware raid, it could just be missing drivers but anyway. As I dunno the configuration you are using this is a little tricky and just a guess... the screenshot you have given seems to imply they are raid5 devices. If this is software raid then what you need to mount would be the raid device rather then directly mounting the hard drive, if your using mdadm it'd be mdx (where x is a number) check to see if their is a md0 or a md1? Might be worth comparing the output of mount from the servers that do detect the drives to those that do not?
