1.How to restore files/catalog from symantec netbackup

On the Client, here we take testserver_bak as example
cat /usr/openv/netbackup/bp.conf
SERVER = testmedia1
SERVER = testmedia2
SERVER = testmedia3
…
CLIENT_NAME = testserver_bak

Then Login to the media server testmedia1, and check the backup.
bplist -C testserver_bak -b -l /export/home/zones/testserver_bak/root/export/home/oracle/arch_mon_main2.sh
-rwxr–r– oracle dba 1213 Feb 13 18:08 /export/home/zones/testserver_bak/root/export/home/oracle/arch_mon_main2.sh
-rwxr–r– oracle dba 1213 Feb 06 18:40 /export/home/zones/testserver_bak/root/export/home/oracle/arch_mon_main2.sh

To restore file/folder from netbackup server side:
bprestore -D testserver_bak -C testserver_bak -L /tmp/restore_log /export/home/zones/testserver_bak/root/export/home/oracle/arch_mon_main2.sh

To restore file/folder from client side:
/usr/openv/netbackup/bin/bprestore -L /tmp/restor_log /export/home/zones/testserver_bak/root/export/home/oracle/arch_mon_main2.sh

You even can specify exact dates for restoration (to restore data from specific date), -s means start date and -e – end date:
/usr/openv/netbackup/bin/bprestore -s 03/13/2012 -e 03/13/2012 -L /tmp/restor_log /apps/kua/
Successful start of restore procedure can be verified with /tmp/restor_log

2.Some other useful symantec netbackup commands

Find the correct backup images

bpimagelist -U -client <CLIENT> -d <STARTDATE> -e <ENDDATE>

Find the media used for those images

bpimagelist -U -client <CLIENT> -d <STARTDATE> -e <ENDDATE> -media

Examples
testserver:root root # bpimagelist -U -client testserver_bak -d 03/01/2012 -e 03/23/2012

Here’s a script to check linux hba model name, firmware version:

#!/bin/ksh
for SCSI in `ls -d /sys/class/scsi_host/host*`;
do
[ -e ${SCSI}/modelname ] && echo -n ‘Model Name ‘ && cat ${SCSI}/modelname;
[ -e ${SCSI}/model_name ] && echo -n ‘Model Name ‘ && cat ${SCSI}/model_name;
[ -e ${SCSI}/fwrev ] && echo -n ‘Firmware Version ‘ && cat ${SCSI}/fwrev;
[ -e ${SCSI}/fw_version ] && echo -n ‘Firmware Version ‘ && cat ${SCSI}/fw_version;
done

Also here’s a script for you if you’re checking bunches of servers:

#!/bin/ksh
USERNAME=”root”
PASSWORD=”yourpassword”
for i in `cat /home/doxer/servers_list_linux`
do
echo “”>/root/.ssh/known_hosts
expect <<EOF
spawn ssh -l${USERNAME} -p22 $i “echo -n ‘====’;hostname;cat /sys/class/scsi_host/host*/{modelname,model_name,fwrev,fw_version}”
set timeout 20
expect “*yes*”
send “yes\r”
expect “assword:”
send “${PASSWORD}\r”
expect eof
EOF
done

For solaris(solaris10), please refer to the following:

#!/bin/ksh
USERNAME=”root”
PASSWORD=”yourpassword”
for i in `cat servers_list_solaris`
do
echo “”>/root/.ssh/known_hosts
expect <<EOF
spawn ssh -l${USERNAME} -p22 $i “hostname;echo ‘result from prtdiag -v’;/usr/sbin/prtdiag -v|grep PCI;echo ‘result from cfgadm -la|grep fabric’;/usr/sbin/cfgadm -la|grep fabric;echo ‘result from fcinfo hba-port’;/usr/sbin/fcinfo hba-port -l|egrep ‘OS Device Name|HBA Port WWN|Manufacturer|Firmware’;echo ‘result from prtpicl -v -c scsi-fcp’;/usr/sbin/prtpicl -v -c scsi-fcp|egrep ‘version|name’”
set timeout 20
expect “*yes*”
send “yes\r”
expect “assword:”
send “${PASSWORD}\r”
expect eof
EOF
done

For solaris 9:

#!/bin/ksh
USERNAME=”root”
PASSWORD=”yourpassword”
for i in `cat servers_list_solaris`
do
echo “”>/root/.ssh/known_hosts
expect <<EOF
spawn ssh -l${USERNAME} -p22 $i “hostname;echo ‘result from prtdiag -v’;/usr/sbin/prtdiag -v|grep PCI;echo ‘result from cfgadm -la|grep fabric’;/usr/sbin/cfgadm -la|grep fabric;echo ‘result from prtpicl -v -c scsi-fcp’;/usr/sbin/prtpicl -v -c scsi-fcp|egrep ‘version|name’”
set timeout 20
expect “*yes*”
send “yes\r”
expect “assword:”
send “${PASSWORD}\r”
expect eof
EOF
done

And if you found the model is like 375-3102-xx or so, then you can just search it in google, you’ll find this one is qlogic X6767A. If the result is like “driver-name   qlc”, “version       ISP2312 Host Adapter fcode version 1.16 11/15/06″, then you’ll know it’s HP ISP2312 and firmware version is 1.16.

If you run ifconfig -a xxx.xxx.xxx.xxx(means an ip address) on solaris box, you’ll find it will give error message:

ifconfig: SIOCSLIFADDR: lo0: Cannot assign requested address

But actually, this command will set the loopback ip address to the one you designated with your command, which means the loopback address will become the ip address other than 127.0.0.1. This is very bad and many weird problems will occur later on, for example, your ssh connection will drop soon after that.

PS:

I’ve also tested it on Linux box and linux will not set loopback ip address to the one designated with the command, but will give error:

error fetching interface information: Device not found

Anyway, do not run ifconfig -a IPADDR on both linux and solaris, or you’ll find your OS in trouble.

We met this error message when trying to import testDG:

VxVM vxdg ERROR V-5-1-10978 Disk group testDG: import failed:
Disk group has no valid configuration copies

Here’s the disks belongs to testDG:
root@doxer# vxdisk -eo alldgs list|grep testDG

And after checking disks’ configuration, we found that some disks were in disabled status:

We may re-initialise config copies on two failing disks from known good state but it was quite risky. Actually, this is a bug in this version of Veritas, whereby it identifies some disks as clones, and some as normal disks. By default, Veritas would refuse to import such “mixed” configuration – it only allows all-normal or all-clones DGs. A work-around is to specify the “-o useclonedev=off” flag or clear the “clone_disk” flag from the disks, i.e. vxdisk set $disk clone=off. After that, we can import the DG without failure. (This is only a workaround though, and furthurmore, we need upgrade Veritas Storage Foundation, and fix the disabled config replicas.)

The assumption is that it’s some sort of bug related to the veritas array library that causes the state of the clone flag to be updated in some cases when an srdf failover is initiated. The inconsistent state of the disk group probably arose because of the inconsistent srdf state of the symdg before the failover. This looks to have been caused by someone adding a new disk to the symdg which was not in a synchronised state. This is similar to what we saw yesterday which also had a disk added to it’s config in an srdf split state and I had to run an establish.

1.expr(Evaluates expressions) is a executable program which belongs to coreutils.

for example:

expr 5 + 1 #returns 6

expr index abcdef a #returns 1

For the full man page of expr, you can try info coreutils expr.

Note:

Other coreutils packages includes:

base64, basename, cat, chcon, chgrp, chmod, chown, chroot, cksum, comm, cp, csplit, cut, date, dd, df, dir, dircolors, dirname, du, echo, env, expand, expr, factor, false, fmt, fold, groups, head, hostid, id, install, join, link, ln, logname, ls, md5sum, mkdir, mkfifo, mknod, mktemp, mv, nice, nl, nohup, nproc, od, paste, pathchk, pinky, pr, printenv, printf, ptx, pwd, readlink, rm, rmdir, runcon, seq, sha1sum, sha224sum, sha256sum, sha384sum, sha512sum, shred, shuf, sleep, sort, split, stat, stdbuf, stty, sum, sync, tac, tail, tee, test, timeout, touch, tr, true, truncate, tsort, tty, uname, unexpand, uniq, unlink, users, vdir, wc, who, whoami, and yes

2.exec & eval

exec and eval are two of  bash builtins.

The typical usage of exec is on some menu-driven UI. For example, you can write a menu-driven program, let’s assume it as menu.viewcards, and then you can put it in the customer’s .bash_profile(bash) or .profile(ksh) the following:

exec menu.viewcards

Now when the customer logs on the shell, that menu will replace the current shell without creating a new process.

And for eval, this is used to execute parameters passed to it. For example:

#cmd=”date –date=\”+ 350 days\”"

#eval $cmd

Firstly, for answer of how to add multiple images on product info page on zencart, please refer to http://tutorials.zen-cart.com/index.php?article=58

Then, if you want to make multiple large images instead of thumbnails on product info page , edit file YourSiteSource/includes/modules/additional_images.php, replace the following lines(First back it up!):
