Display Unallocated Disk Space

[MFederman]

I have an HPUX instance attached to a SAN. Supposedly there is 7.5TB split between this and 1 other HPUX server.

I am using the bdfmegs script to get free space and all I see is

File-System Gbytes Used Avail %Used Mounted on
/dev/vg00/lvol3 20 0 19 2% /
/dev/vg00/lvol1 1 0 1 5% /stand
/dev/vg00/lvol8 20 5 15 25% /var
/dev/vg00/lvol7 15 3 12 20% /usr
/dev/vg00/lvol4 10 0 9 6% /tmp
/dev/vg00/lvol6 30 5 24 19% /opt
/dev/vg00/lvol5 20 3 16 17% /home
/dev/vg01/data 1073 650 396 62% /data

Somewhere I am missing some data. Any ideas on how I can show this? I am a RHEL guy, so I am looking for a 'parted' comparison tool (or something similar).

lvdisplay shows me something, but not what I need.

This is for informix DB's and I believe the data is on RAW partitions, how can I see those?

[MFederman]

Confirmed that it is a raw device it is storing the data on.

How do I see how much space this raw device(s) have?

[Steven E. Protter]

Shalom,

Raw devices will not work with pvdisplay command.

The application that owns the raw disk needs to report on space usage.

vgdisplay -v will show you free space in the volume group and list devices to check with pvdisplay

SEP

I see 2 physical disks, and 2 physical volumes. I KNOW there should be at least 1 more disk that is unformatted/partitioned, but this I cannot identify.

Any ideas for this?

Start with: ioscan -knfCdisk

That will report on all the disks/LUNs (and alternate paths if any). Informix, just like Sybase uses raw partitions. The partitions can be lvols in a volume group or non-LVM whole disks. Only your Informix DBA can identify what disks and lvols are in use. Informix does put some text strings in the first sectors of the disk but there is no HP-UX tool to identify Informix usage.

Once your DBA has identified the disks/LUNs, put comments in /etc/fstab so you and other sysadmins will have some documentation about the raw devices.

sam did it in the end, check volume groups
