ST06 disk information

[Former Member]

Hello All,

We have SAP 4.6c / Oracle / Sun solaris 10. In ST06 -detail analysis menu-under snapshot analysis---DISK

I am getting disk information , there are lots of disks starting with ssdxxx , I would like to know from where this information coming from.

I asked Solaris admin and storage admin, they don't know where these disk number coming from. they are not available at OS level and in storage LUN.

Please reply immediately

Hi,

The figures shown in ST06 can be seen at server level with 'iostat'.

Data in ssd notation:

iostat -cx interval count

For cxdxsx notation add 'n' argument:

iostat -cnx interval count

What filesystem do you use?

What is the exact output you're wondering - can you give me an example?

Here I see e. g.

prtconf -v | more

<...>
                dev=(29,788)
                    dev_path=/scsi_vhci/disk@g600508b40005563a0000900005970000:u
                        spectype=blk type=minor
                        dev_link=/dev/dsk/c0t600508B40005563A0000900005970000d0p4
                        dev_link=/dev/sd98u
                    dev_path=/scsi_vhci/disk@g600508b40005563a0000900005970000:u,raw
                        spectype=chr type=minor
                        dev_link=/dev/rdsk/c0t600508B40005563A0000900005970000d0p4
                        dev_link=/dev/rsd98u
<...>

Here you see that the LUN is mapped to a device /dev/sdxx and /dev/rsdxx for the raw devices.

Try the following to map the SSD disks to the cxdxsx notation:

iostat -E | grep Soft | awk '{ print $1}' > /tmp/a
iostat -En | grep Soft| awk '{ print $1 }' > /tmp/b
paste /tmp/a /tmp/b
