I have a few solaris servers using different filesystem and am have difficulties working out the following:

how do you work out the total size of a disk? the disk space that system is using and unassign? the system is using ufs, md and vxf

How do you increase filesystem size on ufs filesystem?

how do you increase filesystem size on disk suite filesystem?

How do you increase filesystem size on veritas filesystem?


thank in advance

hassan,

- To ufs filesystems with Solstice DiskSuite, check this page :

docs.sun.com - search for "solstice disksuite" ....

- To ufs filesystem, without DiskSuite, we don´t have many options, but if your system have "Volume Manager" from Veritas, you can use this to manage ufs filesystems, like Solstice DiskSuite ...

If you don´t have Volume Manager in your system, you need use "format" tool ... check this in the man pages "man format"...

- To vxfs filesystem, we have the "Volume Manager" in the /opt/VRTSvmsa or /opt/SUNWvxva ... depends of version. And, we have too, the maintenance commands like : "vxedit, vxdg, vxdisk, vxdiskadm".

I hope help you...

You can increase UFS filesystem if you manage to increase the size of the partition it lives in, with the following command:

/usr/lib/fs/ufs/mkfs -G -M /current/mount /dev/rdsk/cXtYdZsA newsize

Specifying the current mount point and raw device as well as the new size in 512 byte blocks.

You can do this even when the filesystem is mounted and in use.

thank for your reply

but how do you work out the total size of a disk? the disk space that system is using and unassign.

I use the format command but this did not show me
the total size of the disk it only shows the size
of each slices.

can you help

When you execute the "format command", you can see this :

Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0t0d0 <SUN4.2G cyl 3880 alt 2 hd 16 sec 135>
/sbus@1f,0/SUNW,fas@e,8800000/sd@0,0
1. c0t1d0 <SUN2.1G cyl 2733 alt 2 hd 19 sec 80>
/sbus@1f,0/SUNW,fas@e,8800000/sd@1,0
Specify disk (enter its number):

In this example, the size of the thisk is in bold ...

The EMC2 has a tool that we can use to see the summary information about the disks in the system. Goes to "ftp.emc.com", /pub/symm3000/inquiry/v5.0.0.1 and get inq.solar26 or nq.solaris (depends of version of Solaris) and exute this with root.

The output of this command is same to :

sysadm01# inq
Inquiry utility, Version 7.06 (SIL Version 4.1.3)

For help type inq -h.
