    My AIX started failing after a reboot with panel code 0518. After booting into recovery mode, fsck of /dev/hd2 fails as follows:

    1. fsck /dev/hd2

    The current volume is: /dev/hd2
    Primary superblock is valid.
    J2_LOGREDO:log redo processing for /dev/hd2
    Primary superblock is valid.
    • Phase 1 - Initial inode scan
    Fatal: I/O error

    Any way to recover from this situation? I can mount the file system from here with mount /dev/hd2 /mnt and I can see its contents but an OS reboot fails with mentioned error 0518.

    insure you do a fsck -y /dev/hd2, fyi: your abstract says "root / fsck fails"... /dev/hd2 is the /usr file sytem (/dev/hd4 is the root filesystem)...again, make sure you specify the -y option to fix the file system, then see if you get the same erro

    You must boot from external method

    from NIM in maintenance mode

    from CD/DVD with SMSmode

    from tape withbSMS mode

    And you can execute fsck on / , /usr

    You can't fsck with / monted
