Please I dont have a lot of redhat skills, but I need some help on creating a file system.
I need to rescan for this new LUN, so I try to check existing LUNs:
Then I try to check for controllers:
Then I try to scan for new disks:
But now I dont seem to see anything usefull in /var/log/messages:
Do you have anything on /dev/sdb1, or is that the new LUN? It's showing as an un-partitioned volume at the moment. I'm guessing that you might want to turn this into a volume group or add it to your existing volume group that /dev/sda2 is in, vg_outsystemdb.
If this is the case, then pvcreate and vgextend will help you.
Can you show use the output for vgdisplay -v so we can avoid anything that already exists.
The output from uname -a would also ensure we give you appropriate commands for your OS version.
If /dev/sdb1 is not your new LUN, a boot should pick it up if that can be arranged.
The volume group vg_outsystemdb is made from just a single disk partition at the moment, /dev/sda2 which is fine. The query you have about /dev/sdb1 is valid, but a boot disk would have an asterix in the Boot column, like /dev/sda1 in this display:-
If the output from df doesn't show any filesystems mounted from device /dev/sdb and you don't have a database that directly uses disk, then I'm pretty confident that you new LUN has been detected as /dev/sdb
My Storage Admin (NetApp) guy, just told me that the problem was actually zoning, so after he actually set up zoning problem, I am now able to view the LUN that he mapped on the system:
Its the 429.5 GB disk shown as /dev/sdc!!

Reason: Changed some ICODE tags to just CODE tags
So are /dev/sdd, /dev/sde & /dev/sdf not needed? Lovely to have three spares of such size too!
Are you looking to grow the existing volume group or add a new one? I suppose the eventual aim is to allocate at least one new filesystem or extend an existing one, but it depends on how you want to allocate the space for what we actually do.
The /dev/sde and on are the same disk, itīs shown like this because there are more that 1 controller on the NetApp.
So now I want to create a new vg and subsequently a new file system, so I believe the order of commands are as follows, please correct me if I am wrong:-

Reason: Consolidated CODE block and converted some CODE tags to ICODE tags and and one CODE tag to set bold.
