Veritas volume manager on solaris 8 1

[andysys]

HI
I want to install & confiure Veritas volume manager on
Solaris 8. I haven't worked before on veritas.I worked on
Solastice Disksuite 4.2.1 .
Total databse size is 1TB.

Can anyone help me on the same ?

Thanks

STEP 1----------------------------------------

We will encapsulate the primary root disk using vxdiskadm.

Encapsulate one or more disks
Menu: VolumeManager/Disk/Encapsulate

Use this operation to convert one or more disks to use the Volume Manager.
This adds the disks to a disk group and replaces existing partitions
with volumes. Disk encapsulation requires a reboot for the changes
to take effect.

More than one disk or pattern cab be entered at the prompt. Here are
some disk selection examples:

all: all disks
c3 c4t2: all disks on both controller 3 and controller 4, target 2
c3t4d2: a single disk

Select disk devices to encapsulate:
[pattern-list>,all,list,q,?] c0t0d0
Here is the disk selected. Output format: [Device_Name]

c0t0d0

Continue operation? [y,n,q,?] (default: y) y
You can choose to add this disk to an existing disk group or to
a new disk group. To create a new disk group, select a disk name that
does not yet exist.

Which disk group [group>,list,q,?] (default: rootdg) rootdg
Use a default disk name for the disk? [y,n,q,?] (default: y) n
NOTE: Make sure you select "n"; we need to call the drive rootdisk.

The selected disks will be encapsulated and added to the rootdg
disk group with disk names that will be specified interactively.

c0t0d0

Continue with operation? [y,n,q,?] (default: y) y

The following disk has been selected for encapsulation.
Output format: [Device_Name]

c0t0d0

Continue with encapsulation? [y,n,q,?] (default: y) y

Enter disk name for [name>,q,?] (default: disk01) rootdisk
The disk device c0t0d0 will be encapsulated and added to the disk group
rootdg with the disk name rootdisk.

The c0t0d0 disk has been configured for encapsulation.

The first stage of encapsulation has completed successfully. You
should now reboot your system at the earliest possible opportunity.

The encapsulation will require two or three reboots, which will happen
automatically after the next reboot. To reboot, execute the command:

shutdown -g0 -y -i6

This will update the /etc/vfstab file so that volume devices are
used to mount the file systems on this disk device. You will need
to update any other references such as backup scripts, databases,
or manually created swap devices.

Encapsulate other disks? [y,n,q,?] (default: n) n

Volume Manager Support Operations
Menu: VolumeManager/Disk

1 Add or initialize one or more disks
2 Encapsulate one or more disks
3 Remove a disk
4 Remove a disk for replacement
5 Replace a failed or removed disk
6 Mirror volumes on a disk
7 Move volumes from a disk
8 Enable access to (import) a disk group
9 Remove access to (deport) a disk group
10 Enable (online) a disk device
11 Disable (offline) a disk device
12 Mark a disk as a hot-spare for a disk group
13 Turn off the hot-spare flag on a disk

Goodbye.

NOTE: We need to reboot for the encapsulation to take effect:

shutdown -g0 -y -i6

This will create volumes around the root partitions. Generally
these volumes will be rootvol, swapvol, var, usr, and export but this
will vary depending on how the rootdisk was originally created/partitioned.
Rebooting will also edit the /etc/system and /etc/vfstab to reflect that the boot
disk is now encapsulated.

STEP 2----------------------------------------

Now we need to prepare the mirror drive by initializing it into
Volume Manager control using vxdiskadm. If you already have the disk
initialized skip this step. You can determine if the disk is already
initialized by doing a 'vxdisk list'. If the disk is online in the
farthest right hand column, that means it has already been initialized.
If the disk shows as error, you will need to initialize it.

Select an operation to perform: 1
Add or initialize disks
Menu: VolumeManager/Disk/AddDisks

Use this operation to add one or more disks to a disk group. You can
add the selected disks to an existing disk group or to a new disk group
that will be created as a part of the operation. The selected disks can
also be added to a disk group as hot spares. The selected disks can also
be initialized without adding them to a disk group leaving the disks
available for use as replacement disks.

More than one disk or pattern may be entered at the prompt. Here are
some disk selection examples:

all: all disks
c3 c4t2: all disks on both controller 3 and controller 4, target 2
c3t4d2: a single disk

Select disk devices to add:
[pattern-list>,all,list,q,?] c0t1d0

Here is the disk selected. Output format: [Device_Name]

c0t1d0

Continue operation? [y,n,q,?] (default: y) y

You can choose to add this disk to an existing disk group, a
new disk group, or leave the disk available for use by future
add or replacement operations. To create a new disk group,
select a disk group name that does not yet exist. To leave
the disk available for future use, specify a disk group name
of "none".

Which disk group [group>,none,list,q,?] (default: rootdg) rootdg

Use a default disk name for the disk? [y,n,q,?] (default: y) n

Add disk as a hot-spare disk for rootdg? [y,n,q,?] (default: n) n

The selected disks will be added to the disk group rootdg with
disk names that you will specify interactively.

c0t1d0

Continue with operation? [y,n,q,?] (default: y) y

The following disk device has a valid VTOC, but does not appear to have
been initialized for the Volume Manager. If there is data on the disk
that should NOT be destroyed you should encapsulate the existing disk
partitions as volumes instead of adding the disk as a new disk.
Output format: [Device_Name]

c0t1d0

Encapsulate this device? [y,n,q,?] (default: y) n

c0t1d0

Instead of encapsulating, initialize? [y,n,q,?] (default: n) y
Initializing device c0t1d0.

Enter disk name for [name>,q,?] (default: disk01) rootmir

Adding disk device c0t1d0 to disk group rootdg with disk
name rootmir.

Add or initialize other disks? [y,n,q,?] (default: n) n

STEP 3----------------------------------------
Step 3 is to setup mirroring from the primary root disk to the mirror disk.
We will use vxdiskadm again to do this.

Mirror volumes on a disk
Menu: VolumeManager/Disk/Mirror

This operation can be used to mirror volumes on a disk. These
volumes can be mirrored onto another disk or onto any
available disk space. Volumes will not be mirrored if they are
already mirrored. Also, volumes that are comprised of more than
one subdisk will not be mirrored.

Mirroring volumes from the boot disk will produce a disk that
can be used as an alternate boot disk.

At the prompt below, supply the name of the disk containing the
volumes to be mirrored.

Enter disk name [disk>,list,q,?] rootdisk

You can choose to mirror volumes from disk rootmirror onto any
available disk space, or you can choose to mirror onto a specific
disk. To mirror to a specific disk, select the name of that disk.
To mirror to any available disk space, select "any".

Enter destination disk [disk>,list,q,?] (default: any) rootmir

The requested operation is to mirror all volumes on disk rootdisk
in disk group rootdg onto available disk space on disk rootmirror.

NOTE: This operation can take a long time to complete.

Continue with operation? [y,n,q,?] (default: y) y

Mirror volume rootvol ...

This message will be repeated for all volumes that are mirrored until it is complete.
Run:
vxprint -htg rootdg

To verify that the mirroring is set up when vxdiskadm is complete.

Hi

Thanks for the valuable information.One more thing can
you tell me how to do concatanation & RAID 5.

Andy

 

[Apricot]

RAID 5:


1. Create a disk group using Volume Manager with a minimum of 4 disks:

# vxdg init datadg disk01=c1t1d0s2 disk02=c1t2d0s2 disk03=c1t3d0s2 disk04=c1t4d0s2
# vxassist -g datadg make vol01 2g layout=raid5

2. Create a mount point for this volume:

# mkdir /vol01

3. Create a file system on this volume:

# mkfs -F vxfs /dev/vx/rdsk/datadg/vol01


Concatenated:

# vxassist -g datadg make datavol 10m


or to create a concatenated volume on specific disks:


# vxassist -g datadg make datavol 3m datadg02 datadg03
