Register, Mount, and Verify the File Systems To register the new file systems in the mount table: 1. Make a backup copy of the mount table by entering cp /etc/fstab /etc/fstab.backup 2. Edit the file /etc/fstab by using the vi editor. Example # cp /etc/fstab /etc/fstab.backup # vi /etc/fstab /dev/root / xfs rw,raw=/dev/rroot 0 0 /dev/dsk/dks5d4s7 /disk54 efs rw,raw=/dev/rdsk/dks5d4s7 0 0 /dev/dsk/dks5d4l1s7 /disk541 efs rw,raw=/dev/rdsk/dks5d4l1s7 0 0 /dev/dsk/dks5d4l2s7 /disk542 efs rw,raw=/dev/rdsk/dks5d4l2s7 0 0 /dev/dsk/dks5d4l3s7 /disk543 efs rw,raw=/dev/rdsk/dks5d4l3s7 0 0 /dev/dsk/dks5d4l4s7 /disk544 efs rw,raw=/dev/rdsk/dks5d4l4s7 0 0 /dev/dsk/dks4d4s7 /HP5700_LU0 efs rw,raw=/dev/rdsk/dks4d4s7 1 2 /dev/dsk/dks4d4l1s7 /HP5700_LU1 efs rw,raw=/dev/rdsk/dks4d4l1s7 1 2 /dev/dsk/dks4d4l2s7 /HP5700_LU2 efs rw,raw=/dev/rdsk/dks4d4l2s7 1 2 /dev/dsk/dks4d4l3s7 /HP5700_LU3 efs rw,raw=/dev/rdsk/dks4d4l3s7 1 2 1 2 3 4 56 1 Device to mount (device file name) 2 Mount point (mount directory) 3 File system (FS) type 4 Mount options (usually [rw,noquota]) 5 Enhance: enter 0 for disk array devices 6 fsck pass: order in which FS checks are to be performed 3. Add a line in the file for each new file system. For example, to register an EFS file system for the device at controller 4, disk 4, LUN 3, slice 7, mounted on the /HP5700_LU0 directory, enter /dev/dsk/dks4d4l3s7 /HP5700_LU0 xfs rw,raw=/dev/rdsk/dks4d4l3s7 1 2 For example, to register an XFS file system for the device at controller 4, disk 4, LUN 3, slice 7, mounted on the /HP5700_LU0 directory, enter /dev/dsk/dks4d4l3s7 /HP5700_LU0 xfs rw,raw=/dev/rdsk/dks4d4l3s7 1 2 4. When you are finished adding the new file systems to the mount table, save the changes and exit the vi editor. 5. Verify that the new file systems are registered correctly by entering df Example # df File system /dev/root /dev/dsk/dks4d4s7 /dev/dsk/dks4d4l1s7 /dev/dsk/dks4d4l2s7 /dev/dsk/dks4d4l3s7 : : # Type xfs efs efs efs efs Blocks 1852624 4659286 4659286 4659286 4659286 use 1038184 2 2 2 2 avail 814440 4193354 4193354 4193354 4193354 %use 57 0 0 0 0 Mounted on / /HP5700_LU0 /HP5700_LU1 /HP5700_LU2 /HP5700_LU3 SGI IRIX Installation 33
