Hi all, I've got a server running Red Hat: It has some SCSI storage attached but I can't see it...I've tried the usual devfsadm and cfgadm commends, but they aren't recognised, and neither is format or rmformat.... I've found that mountall is translated to mount -a but it says there is an error in fstab, this line isn't correct: It's a different syntax to what I'm used to so I'm not sure what's up... Anyone got any ideas? Cheers, Ben

I'm afraid I can't help at all. But I do have a red hat server with a raid attached via scsi if there's anything on it I can check out if that helps!

My experience of adding storage to Centos boxes is that you need to reboot despite what EMC's PowerPAth documentation tells you! I'm guessing you've already tried it.
Is there anything useful in /var/log/messages?
I can't remember the exact sequence of commands to ad storage, but I can post my normal SOP from work if it's any help tomorrow.

That would be grand  I wondered why I couldn't see storage in the first place, then found that the SCSI cable was lighting up a link light on the storage...Yet the storage hod no power going to it  I powered off the server, powered on the storage and powered the server back on, but it didn't pick it up...I think it's the /etc/fstab file that is wrong... I'll look in /var/log/messages tomorrow, I didn't think of looking there because there was nothing that was printed onto the console saying anything about storage...(During boot up or otherwise) Thanks all Ben

Hi all, I managed to put this work on the back burner for a bit, but I've just gone back to it... After doing a fair amount of reading, I've found that the SCSI array has nine of ten disks (36GB), these have been put into some kind of volume using something called LVM. Using pvscan I can see the hard drives and I can see what VG they are in...But I have no idea where this new volume has been mounted, or what command to use to find more details on the volume... Can anyone give me a quick how-to on LVM (the documentation on the net tells you have to create a remove, but not list), I need to know what the final volume is called, then how to mount it... Many thanks all Ben

I've got a little further...I now know this: It's the second entry I want...'/dev/vm_group/vmware_disk' can't be found, it's not there, and I' think it might have something to do with this "inactive" thing (some sort of status?) Anyone know how to make it active? Cheers, Ben

I strayed onto a gentoo page and found the command vgchange with arguments -a y. Looks like it's sorted! Just got to fix fstab now!
