Dear Members,
I am using SCO-Unix 5.0.5. I have created 2 logical drives but some of the blocks are overlapped and are now giving warning during startup. I have used fsck to settle the problems but to no avail. Kindly help me to sort out the problem.

I've created a partition with GNU Parted, how do I mount the partition?
The manual information at http://www.gnu.org/software/parted/manual/parted.html is good, but I am sure about how I mount the partition afterwards.
Thanks,

I have created a pool named earthpool using zpool command. Later I created a file system named earth using zfs command. I changed the mountpoint of earth (file system) using
zfs set mountpoint=/earth earthpool/earth.
Where /earth is a directory created in root using mkdir.
Now, I have a... (8 Replies)

Hi all,
I am using SPARC Solaris 11.1 with EFI labelled disks.
I am new to ZFS file systems and slightly stuck when trying to create a partition (slice) on one of my LUNs.
EFI labels use sectors and blocks and I am not sure how exactly it works.
From here I can try and create a... (2 Replies)

rp
RP(4) Kernel Interfaces Manual RP(4)NAME
rp - RP-11/RP03 moving-head disk
DESCRIPTION
The files rp0 ... rp7 refer to sections of RP disk drive 0. The files rp8 ... rp15 refer to drive 1 etc. This allows a large disk to be
broken up into more manageable pieces.
The origin and size of the pseudo-disks on each drive are as follows:
disk start length
0 0 81000
1 0 5000
2 5000 2000
3 7000 74000
4-7 unassigned
Thus rp0 covers the whole drive, while rp1, rp2, rp3 can serve usefully as a root, swap, and mounted user file system respectively.
The rp files access the disk via the system's normal buffering mechanism and may be read and written without regard to physical disk
records. There is also a `raw' interface which provides for direct transmission between the disk and the user's read or write buffer. A
single read or write call results in exactly one I/O operation and therefore raw I/O is considerably more efficient when many words are
transmitted. The names of the raw RP files begin with rrp and end with a number which selects the same disk section as the corresponding
rp file.
In raw I/O the buffer must begin on a word boundary.
FILES
/dev/rp?, /dev/rrp?
SEE ALSO hp(4)BUGS
In raw I/O read and write(2) truncate file offsets to 512-byte block boundaries, and write scribbles on the tail of incomplete blocks.
Thus, in programs that are likely to access raw devices, read, write and lseek(2) should always deal in 512-byte multiples.
