SAN: Calriion CX3-10C How can I increase size of LUN (50GB) attached to Linux Red Hat host (RHEL 5.2) 64bit by adding new created LUN (200GB)?  What steps do we need to take to get the Linux host to see the new space? I am going to present a new LUN from EMC array to the Linux system.   The existing system partion it looks: # fdisk -l  Disk /dev/sda: 72.7 GB, 72746008576 bytes 255 heads, 63 sectors/track, 8844 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes    Device Boot      Start         End      Blocks   Id  System /dev/sda1   *           1          13      104391   83  Linux /dev/sda2              14        8844    70935007+  8e  Linux LVM  Disk /dev/sdb: 53.6 GB, 53687091200 bytes 64 heads, 32 sectors/track, 51200 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes    Device Boot      Start         End      Blocks   Id  System /dev/sdb1               1       51200    52428784   8e  Linux LVM  Disk /dev/sdc: 53.6 GB, 53687091200 bytes 64 heads, 32 sectors/track, 51200 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes    Device Boot      Start         End      Blocks   Id  System /dev/sdc1               1       51200    52428784   8e  Linux LVM  Disk /dev/sdd: 53.6 GB, 53687091200 bytes 64 heads, 32 sectors/track, 51200 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes    Device Boot      Start         End      Blocks   Id  System /dev/sdd1               1       51200    52428784   8e  Linux LVM  Disk /dev/sde: 53.6 GB, 53687091200 bytes 64 heads, 32 sectors/track, 51200 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes    Device Boot      Start         End      Blocks   Id  System /dev/sde1               1       51200    52428784   8e  Linux LVM  Disk /dev/emcpowera: 53.6 GB, 53687091200 bytes 64 heads, 32 sectors/track, 51200 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes          Device Boot      Start         End      Blocks   Id  System /dev/emcpowera1               1       51200    52428784   8e  Linux LVM
