Query regarding kernel upgrade
Soon we are going for kernel upgrade, OS is HPUX.
1) Do we need to download latest version of SAPCAR for extracting the *.SAR files?
Pls have a look on steps involved for kernel upgrade and let me know if i m missing something
1) Take backup of current kernel directory-:
cp * /tmp/backup_kernel_old
2) Download latest kernel from service maket place put it in directory latest_kernel
chown prdadm:sapsys *
3) Give permissions
chmod 777 latest_kernel
4) Upgrade the kernel using following commands
./SAPCAR -xvf SAPEXE_* -R /sapmnt/PRD/exe
./SAPCAR -xvf SAPDB_* -R /sapmnt/PRD/exe
Please suggest me if I m missing something or anything in these steps is wrong.
