Sun OTP Host Disk Drive Partition Requirements

Slice 

Partition 

Size 

0 

/ (root)

For high availability, it is recommended that the root partition is mirrored. See Solaris Volume Manager Administration Guide for more information.

All remaining free space on the disk after allocating space for slices 2 through 7. 

1 

swap

Two to three times total system RAM, or 4096 Mbytes, whichever is greater. 

2 

overlap 

The entire system disk. 

3 

/globaldevices

512 Mbytes minimum. 

The Sun OTP high availability service later assigns this slice a different mount point and mounts the slice as a cluster file system. 

/globaldevices can reside on any unused slice on any disk on the server. Failure to allocate /globaldevices on a Sun OTP system will cause Sun Open Telecommunications Platform to fail.

4 through 6 

unused 

Not used. 

7 

Solaris Volume Manager 

128 Mbytes 

Used by Solaris Volume Manager software for the state database replica.
