Solved: AIX: Unable to read either superblock.

By Saket Jain Published December 1, 2021 AIX

Today in this post we will check what to do in case we are not able to read either superblock of a SAN disk on server.

This is a common issue that appears when a disk is removed and represented on a server either by mistake or due to some network issue.

I. Issue/Error

ngeaix001 --> cd RMAN

ngeaix001 --> ls -ltr
ls: .: There is an input or output error.

II. Initial Analysis

In this case, the first approach to solve the issue is to umount, run FSCK and then mount this partition back. Lets try to perform this action.

ngeaix001 --> pwd
/backup/B4UcloneDTB/RMAN

ngeaix001 --> lsof /backup/B4UcloneDTB/
ksh: lsof:  not found.

ngeaix001 --> fuser -cu /backup/B4UcloneDTB/
/backup/B4UcloneDTB/:

ngeaix001 --> df -g /backup/B4UcloneDTB/
Filesystem    GB blocks      Free %Used    Iused %Iused Mounted on
/dev/clonelv    3300.00    501.08   85%      435     1% /backup/B4UcloneDTB

ngeaix001 --> umount /backup/B4UcloneDTB/
umount: 0506-349 Cannot unmount /dev/clonelv: The requested resource is busy.

ngeaix001 --> umount -f /backup/B4UcloneDTB/
forced unmount of /backup/B4UcloneDTB
forced unmount of /backup/B4UcloneDTB

ngeaix001 --> df -g /backup/B4UcloneDTB/
Filesystem    GB blocks      Free %Used    Iused %Iused Mounted on
/dev/backlv      449.81     67.38   86%      143     1% /backup

ngeaix001 --> mount /backup/B4UcloneDTB/
mount: 0506-334 /backup/B4UcloneDTB/ is not a known file system.

ngeaix001 --> mount /dev/clonelv /backup/B4UcloneDTB
mount: 0506-324 Cannot mount /dev/clonelv on /backup/B4UcloneDTB: There is an input or output error.

ngeaix001 --> fsck -y /dev/clonelv
The current volume is: /dev/clonelv
Unable to read primary superblock.
Unable to read either superblock.

ngeaix001 --> fsck -p /dev/clonelv
The current volume is: /dev/clonelv
Unable to read primary superblock.
Unable to read either superblock.
ngeaix001 -->

III. Solution

Since FSCK is not working and showing error that superblock is corrupt.

We need to delete this disk from server, re-scan the disk and import it in VG back.

It involves the step to vary off the VG, deleting disk, re-scan disk back, and importing the respective VG/disk to mount on server.

Lets have a look at various steps.

### First list all the VGs.
ngeaix001 --> lsvg -L
rootvg
productsvg
products1vg
products2vg
data1vg
data2vg
logs1vg
logs2vg
backup1vg
backup2vg
backupvg
products3vg
backup3vg
logs3vg
data3vg
clonevg

### Now try to list the VG whose partition was showing error.
ngeaix001 --> lsvg -l clonevg
0516-062 : Unable to read or write logical volume manager
        record. PV may be permanently corrupted. Run diagnostics

### Now vary off the VG.	
ngeaix001 --> varyoffvg clonevg
0516-062 lqueryvg: Unable to read or write logical volume manager
        record. PV may be permanently corrupted. Run diagnostics
0516-062 : Unable to read or write logical volume manager
        record. PV may be permanently corrupted. Run diagnostics

### Export this VG now
ngeaix001 --> exportvg clonevg

### Check out the disks available.
ngeaix001 --> lsdev -Cc disk

### remove the disk from server.
ngeaix001 --> rmdev -dl hdisk18
hdisk18 deleted

### re-scan the attached LUNs/disks
ngeaix001 --> cfgmgr

### Check out the disks again
ngeaix001 --> lsdev -Cc disk

### Now we can see which disk not assigned to any VG.
