HP StorageWorks Disk Array XP operating system configuration guide for Sun Solaris XP24000, XP12000, XP10000, SVS200, v01(A5951-96037, June 2007)

CAUTION:
The repair, analyze, defect, and verify commands/menus are not applicable to the XP arrays and SVS200.
When selecting disk devices, be careful to select the correct disk as using the partition/label commands
on disks that have data can cause data loss.
1. Enter format at the root prompt to start the utility.
2. Verify that all new devices are displayed. If they are not, exit the format utility (quit or Ctrl-D),
and ensure the Fibre Channel-to-LDEV paths were defined correctly for all devices and that all
new devices were added to the driver configuration file.
3. Record the character-type device file names (for example, c1t2d0) for all the new disks. You will
use this data either to create the file systems or to use them with the Sun or Veritas Volume
Manager.
4. When you are asked to specify the disk, enter the number of the device to be labeled.
5. When you are asked if you want to label the disk, enter y for “yes.”
6. If you are not using Veritas Volume Manager, use the partition command to create or adjust the
slices (partitions) as necessary.
7. Repeat this labeling procedure for each new device (Use the disk command to select another
disk).
8. When you finish labeling the disks, enter quit or press Ctrl-D to exit the format utility.

Creating the file systems
1. If you want to create a UFS file system, create the file system using the newfs –Cmaxcontig
command.
Example
# newfs -C 6 /dev/rdsk/c1t2d0s0
Use 6 or one of the following multiples of 6 as the maxcontig value for all disk array OPEN-x
devices: 12, 18, 24, or 30.
If you use 6, the Sun OS will access 48 KB as a unit (6*8 KB), which matches the track size of
the OPEN-x devices. These maxcontig values (6, 12, 18, 24, 30) optimize the I/O performance
of the disk array by keeping the I/O data range on one track. The maxcontig value that you
choose depends on your applications, and you can change the maxcontig parameter to a
different value at any time.
Use the character-type device file (for example, /dev/rdsk/c1t2d0s0) as the argument.
2. When the confirmation appears, enter y for yes if the file name is correct. If the file name is not
correct, enter n and repeat step 1.
3. Repeat this procedure for each new OPEN-x device. Use the same maxcontig value for all disk
array devices.
