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:
Code:
fdisk -l
Disk /dev/sda: 299.4 GB, 299439751168 bytes
255 heads, 63 sectors/track, 36404 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda1 * 1 64 512000 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 64 36405 291908608 8e Linux LVM
Disk /dev/sdb: 598.9 GB, 598879502336 bytes

/dev/sdb1 1 72809 584838261 83 Linux
Disk /dev/mapper/vg_outsystemdb-lv_root: 53.7 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/mapper/vg_outsystemdb-lv_swap: 29.6 GB, 29611786240 bytes
255 heads, 63 sectors/track, 3600 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Then I try to check for controllers:
Code:
ls -lrt /sys/class/fc_host
total 0
lrwxrwxrwx. 1 root root 0 Nov 20 15:26 host2 -> ../../devices/pci0000:00/0000:00:07.0/0000:06:00.1/host2/fc_host/host2
lrwxrwxrwx. 1 root root 0 Nov 20 15:26 host1 -> ../../devices/pci0000:00/0000:00:07.0/0000:06:00.0/host1/fc_host/host1
Then I try to scan for new disks:
Code:
echo "1" > /sys/class/fc_host/host2/issue_lip
But now I dont seem to see anything usefull in /var/log/messages:
Code:
tail /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.
I wouldīnt know if /dev/sdb1 is a new LUN, and the output of vgdisplay -v is

Does the /dev/sdb1 not a boot partition? as it says on the output of fdisk -l:

Reason: Changed some CODE tags to ICODE
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:-
Code:
Device Boot Start End Blocks Id System
/dev/sda1 * 2 501 512000 83 Linux
/dev/sda2 502 16384 16264192 8e Linux LVM
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:

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:-
