I am trying to do root volume mirroring on SunFire V210 server. I have two disks in it.First one is c1t0do and second one is c1t1do. Both disks already have partitions in them so I am deleting the partitions of second disk(c1t1do) using format command and selecting cylinder start 0 and size 0mb. When I do the same on partition 6 I could not able to label the partition 6 and its shows an error. Please help me . Thanks in advance.

Solution : You should never make size of slice 2 0mb.
:confused: Hello,
In my Solaris system, I want to resize my mounted home directory slice.
1.I unmount the slice, #umount /export/home
2.Resize the directory #format>partition>
3.#format>label
4.#format>Cannot label disk when partitions are in use as described.
So, How can label ?

Hi Fellows,
I am trying to mirror 2 identical disks on a SUN Ultra 10 machines (with new installation of Solaris 8). In the process, I found 2 issues:
1. prtvtoc /dev/rdsk/c0t0d0s0 | fmthard -s - /dev/rdsk/c0t1d0s0
Result: Disk partitions between the 2 disks do not match up.

Hi,
Recently I faced with need of analyze root disk. I figured out two possible ways to do it:
1. Practical. Boot from CD and run format
2. Theoretical. Create live upgrade boot environment on another disk, activate it, reboot, unmont all root disk partitions and run format.

Hi there,
I'm wondering how to display a disk label (why not edit it but I don't need that yet).
I found several commands on forums like disklabel and diskinfo but I can't find them on my system and don't know the package they belong to.
Can you help me?
Cheers

we have a ZFS file system that was created as a pool of just one disk (raid on a SAN) when this was created it was done as a whole disk, and so EFI label.
now we want to mount this file system into an LDOM.
my understanding of how ldom's and disk works this is that we can only do this as a... (1 Reply)
Hi Guys,
Do you have any script to label a disk automatically.
It is part of my script but I am not able to find solution to label this inside script without user intervention. (2 Replies)

fmthard(1M)fmthard(1M)NAME
fmthard - populate label on hard disks
SYNOPSIS
SPARC
fmthard -d data | -n volume_name | -s datafile [-i] /dev/rdsk/c? [t?] d?s2
fmthard -d data | -n volume_name | -s datafile [-i] /dev/rdsk/c? [t?] d?s2
The fmthard command updates the VTOC (Volume Table of Contents) on hard disks and, on systems, adds boot information to the Solaris fdisk
partition. One or more of the options -s datafile, -d data, or -n volume_name must be used to request modifications to the disk label. To
print disk label contents, see prtvtoc(1M). The /dev/rdsk/c?[t?]d?s2 file must be the character special file of the device where the new
label is to be installed. On systems, fdisk(1M) must be run on the drive before fmthard.
If you are using an system, note that the term ``partition'' in this page refers to slices within the fdisk partition on machines. Do
not confuse the partitions created by fmthard with the partitions created by fdisk.
The following options are supported:
-d data The data argument of this option is a string representing the information for a particular partition in the current
VTOC. The string must be of the format part:tag:flag:start:size where part is the partition number, tag is the ID
TAG of the partition, flag is the set of permission flags, start is the starting sector number of the partition,
and size is the number of sectors in the partition. See the description of the datafile below for more information
on these fields.
-i This option allows the command to create the desired VTOC table, but prints the information to standard output
instead of modifying the VTOC on the disk.
-n volume_name This option is used to give the disk a volume_name up to 8 characters long.
-s datafile This option is used to populate the VTOC according to a datafile created by the user. If the datafile is "-",
fmthard reads from standard input. The datafile format is described below. This option causes all of the disk par-
tition timestamp fields to be set to zero.
Every VTOC generated by fmthard will also have partition 2, by convention, that corresponds to the whole disk. If
the input in datafile does not specify an entry for partition 2, a default partition 2 entry will be created auto-
matically in VTOC with the tag V_BACKUP and size equal to the full size of the disk.
The datafile contains one specification line for each partition, starting with partition 0. Each line is delimited
by a new-line character (
). If the first character of a line is an asterisk (*), the line is treated as a com-
ment. Each line is composed of entries that are position-dependent, separated by "white space" and having the fol-
lowing format:
partition tag flag starting_sector size_in_sectors
where the entries have the following values:
partition The partition number. Currently, for Solaris SPARC, a disk can have up to 8 partitions, 0-7. Even
though the partition field has 4 bits, only 3 bits are currently used. For , all 4 bits are used to
allow slices 0-15. Each Solaris fdisk partition can have up to 16 slices.
tag The partition tag: a decimal number. The following are reserved codes: 0 (V_UNASSIGNED), 1
(V_BOOT), 2 (V_ROOT), 3 (V_SWAP), 4 (V_USR), 5 (V_BACKUP), 6 (V_STAND), 7 (V_VAR), and 8 (V_HOME).
flag The flag allows a partition to be flagged as unmountable or read only, the masks being: V_UNMNT
0x01, and V_RONLY 0x10. For mountable partitions use 0x00.
starting_sector The sector number (decimal) on which the partition starts.
size_in_sectors The number (decimal) of sectors occupied by the partition.
You can save the output of a prtvtoc command to a file, edit the file, and use it as the datafile argument to the
-s option.
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWcsu |
+-----------------------------+-----------------------------+
uname(1), format(1M), prtvtoc(1M), attributes(5)

fdisk(1M), installgrub(1M)
Special care should be exercised when overwriting an existing VTOC, as incorrect entries could result in current data being inaccessible.
As a precaution, save the old VTOC.
For disks under one terabyte, fmthard cannot write a VTOC on an unlabeled disk. Use format(1M) for this purpose.
