Posted by Lincoln Zuljewic Silva in Aix on February 18th, 2010
To check the amount of physical RAM that a AIX Server has, you can use the following commands:
| lsattr -El sys0 | grep realmem realmem 16121856 Amount of usable physical memory in Kbytes |
or
| lsattr -El mem0 goodsize 15744 Amount of usable physical memory in Mbytes False size 15744 Total amount of physical memory in Mbytes False |
or
| prtconf|grep "Memory Size" Memory Size: 15744 MB Good Memory Size: 15744 MB |

Recovering corrupted lvol on HP-UX
Posted by Lincoln Zuljewic Silva in HP-UX on May 14th, 2009
Sometimes you can get the following error while try to access a directory in HP-UX:
|
hpuxbox@root:/root # cd /DATA sh: /DATA: The specified directory is not valid. |
This error is caused because the file system is corrupted and you need run fsck on it.
First of all, umount the FS:
|
hpuxbox@root:/root # umount /DATA |
And them, run the fsck:
|
hpuxbox @root:/root # fsck -y -o full /dev/vgLOG/lvol1on clear? (ynq)y UX:vxfs fsck: WARNING: V-3-20836: file system had I/O error(s) on meta-data. log replay in progress pass0 – checking structural files pass1 – checking inode sanity and blocks fileset 999 primary-ilist inode 177502 marked bad, allocation flags (0×0001) fileset 999 primary-ilist inode 177502 has invalid number of blocks (7309) fileset 999 primary-ilist inode 177502 has invalid block map fileset 999 primary-ilist inode 177502 failed validation clear?

After that, you can mount the FS again.

hpuxbox@root:/root # umount /DATA |
