Hi Guys

From now onwords I am going to create and publish knowledge base articles by which you can find solutions for the error messages or some known errors. Hope this will help guys work with solaris and storage.

Knowledge Base Article: SOLSAT0001

Problem/ Error Message:

VxVM vxassist WARNING V-5-1-1402 Your license does not include support for striping
Striping layout disabled.Defaulting to concat.

VxVM vxassist ERROR V-5-1-435 Cannot allocate space for 284774400 block volume

Host Name: dbhost1

Server Model: Sun Fire 4800

OS/ version: Solaris 8

Software Involved: Veritas VXVM

Version: 4.1

Reason / Analysis:

VERITAS License expired.

Description:

When trying to run vxassist command to create a stripe volume the following error appeared.
dbhost1# vxassist -g DW2sbdg make data201 284774400 layout=stripe sc5-9585-4-FB08-096-PG08-00 sc5-9585-4-FB09-107-PG09-00 sc5-9585-4-FB10-118-PG10-00 sc5-9585-4-FB11-129-PG11-00

Tried vxassist with the concat option but did not work.
Next checked the vxlicense with the following command
# /sbin/vxlicrep

Action Taken:

Called VERITAS Technical Support

Toll Free Number: 1-800-342-0652

Veritas TSE will ask for a VSN number give this one below:

VSN Number: xxx-xxxx-xxxx

Resolution:

VERITAS gave a temporary 60 days license and it has been installed.

Storage Foundation for Oracle-Enterprise, Solaris, v4.1, 60 Day Evaluation License: RJPG-PJJP-D3RD-ZS77-9GO3-4MSJ-ZP

Here are the commands to install the temporary license.

dbhost1# /sbin/vxlicinst

VERITAS License Manager vxlicinst utility version 3.02.005

Enter your license key: RJPG-PJJP-D3RD-ZS77-9GO3-4MSJ-ZP

You will get a message license installed successfully.

Now again you can check with the “Vxlicrep” command to verify if the license are installed properly and whether the products and options are enabled or not.

And without any reboot the vxassist commands worked fine with all options.

VXVM - How to extend Volumes using vxresize and vxassist

1. Verify free space on underlying device:

# vxdg -g datadg free

from the output you will see disks length starts from "0", those disks are free.

# vxassist -g datadg maxsize layout=concat or layout=stripe

# vxassist -g datadg maxgrow datavol

2. Expand the volume using vxassist:

example: #vxassist -g testdg growto datavol 4096000

3. Expand the file system using fsadm:

# fsadm -F vxfs -b "newsize" -r /dev/vx/rdsk/testdg/datavol /datavol

4. Verify that the file system was resized by using df:

# df -k /datavol

The volume can be increased using vxresize command also,

For vxresize command "fsadm" is not required.

in the below example the volume "datavol" is increased from 2GB to 4Gb.

NOTE: you need to mention the total size which the volume need to be grown.

First determine the free space available:

# vxassist -g datadg maxsize layout=concat or layout=stripe

# vxassist -g datadg maxgrow datavol

Determine the filesystem type:

fstyp /datamount or fstyp -v /dev/vx/rdsk/testdg/datavol

# vxresize -b -g testdg datavol 4G or

vxresize -g testdg datavol +2g

Check with df -h or df -k to check if the FS is grown.

HP-UNIX Volume Manager Tasks

Hi,
I found a good document on hp-ux LVM and like to share with you guys.

HP-UX: Disk and Filesystem tasks
Search for attached disk
ioscan -fnC disk
Initialize a disk for use with LVM
pvcreate -f /dev/rdsk/c0t1d0
Create the device structure needed for a new volume group.
cd /dev
mkdir vgdata
cd vgdata
mknod group c 64 0x010000
Create volume group vgdata
vgcreate vgdata /dev/dsk/c0t1d0
{ if your expecting to use more than 16 physical disks use the -p option, range from 1 to 256 disks. }
Display volume group vgdata
vgdisplay -v vg01
Add another disk to volume group
pvcreate -f /dev/rdsk/c0t4d0
vgextend vg01 /dev/dsk/c0t4d0
Remove disk from volume group
vgreduce vg01 /dev/dsk/c0t4d0
Create a 100 MB logical volume lvdata
lvcreate -L 100 -n lvdata vgdata
newfs -F vxfs /dev/vgdata/rlvdata
Extend logical volume to 200 MB
lvextend -L 200 /dev/vgdata/lvdata
Extend file system to 200 MB
{ if you don't have Online JFS installed volumes must be unmounted before you can extend the file system. }
fuser -ku /dev/vgdata/lvdata { kill all process that has open files on this volume. }
umount /dev/vgdata/lvdata
extendfs /data
{ for Online JFS, 200 MB / 4 MB = 50 LE; 50 x 1024 = 51200 blocks }
fsadm -F vxfs -b 51200 /data
Set largefiles to support files greater than 2GB
fsadm -F vxfs -o largefiles /data

Exporting and Importing disks across system.
1. make the volume group unavailable
vgchange -a n /dev/vgdata
2. Export the the disk while creating a logical volume map file.
vgexport -v -m data_map vgdata
3. Disconnect the drives and move to new system.
4. Move the data_map file to the new system.
5. On the new system recreate the volume group directory
mkdir /dev/vgdata
mknod /dev/vgdata/group c 64 0x02000
6. Import the disks to the new system
vgimport -v -m data_map /dev/vgdata /dev/dsk/c2t1d0 /dev/dsk/c2t2d0
7. Enable the new volume group
vgchange -a y /dev/vgdata
Renaming a logical volume
/dev/vgdata/lvol1 -> /dev/vgdata/data_lv
umount /dev/vgdata/lvol1
ll /dev/vgdata/lvol1 take note of the minor ( e.g 0x010001 )
brw-r----- 1 root root 64 0x010001 Dec 31 17:59 lvol1
mknod /dev/vgdata/data_lv b 64 0x010001 create new logical volume name
mknod /dev/vgdata/rdata_lv c 64 0x010001
vi /etc/fstab { reflect the new logical volume }
mount -a

rmsf /dev/vgdata/lvol1
rmsf /dev/vgdata/rlvol1

Following the Rules

Not everyone follow all the rules.
When you take up the advice from someone, you have to follow it.
Just thinking about the guys who have got a chance in a short period will not give you a same kind of break.
we may have to prepare within the available free time and the environment we get to get into that position.
Some of the guys actually my friends have taken the first step of my advice "Completing a Certification".
This is a great achievement. A certification is like a graduation or even more than that, as I feel.
A degree like BE alone will not give you a job nowadays and also Diploma with many years of experience also will not get you a right job which you want.
But a certification relevant to your experience or interest will really get you a good job.
Now I have two three real time experience ie some of the guys who take up my advice got placed in good companies now.
Will tell you the full story(case study) later. I guided him through the whole process and finally he got into a good concern that too into a job he was really interested into.
To achieve anything you have to work out. Nowadays there is a big challenge for really skilled guys.
Wherein people make fake Resumes and give fake interviews and also arrange somebody to attend the interviews and they get into the job. So the real talents are missing the opportunity and left unnoticed.
But nowadays all the concern take necessary steps to filter the fake Resumes and do the background check thorough to find out those guys.
UNIX interviews will the toughest in all interviews and we have to prepare in all aspect before attending the interview.

San Jose Work Experience

The office environment was good in san jose.
But most of the team members work from home.
Those guys in onsite work very hard and for long working hours. But equally they spend time during week ends and they have the liberty of working from home. And since they have blackberry they can travel during oncall so that they login only while they get alerts.
Advantage over there compared to working here is, whatever doubts you have or request you have we can get it clarified immediately directly from the onsite guys.
And we can attend meetings with all the teams and our teams. also meet the other team members and create good relationship.
breakout rooms are really good with pepsi and coke free and with some snacks.
other few breakrooms are there with fruits and varieties of corn flakes.
quite often we have some functions like chinese new year and other parties like st.patricks day organised in the office in a big hall organised with drinks and dinner or lunch.
we can get a experience of working with americans, chinese, russians etc.

My onsite trip to San Jose

Hi guys
I came to San Jose, California,USA the so called "Silicon Valley".
It is 40 miles away from San Fancisco.
Hope will be here for another two months.
Have many things to share with you guys on this trip.
Whenever I get time I will update, since work is hectic here.
