Did you remove the disk physically from the server without administrative action an the AIX side? Whenever you are going to remove a disk permanently from an AIX server you need to remove certain pieces of information from the system. You start with the LVM level: stop access to the filesystems, unmount the filesystems, varyoff the VG. Export the VG if you are sure that it will never return (on this particular disk). (Check exportvg and reducevg commands to find out which one applies to you) Then go on by removing the information at the device level: remove the disk's entries from the ODM with rmdev -dl. Only then remove the disk itself. Stick to this sequence as the LVM level commands depend on the ODM entries.
As to the lspv: lspv shows the disks that where available during boot time. Hence it would be better to use lsdev -Ccdisk (or from AIX 5.2 on lsdev -cdisk) to find out which disks are available in the system and whether they are active or defined.

I did crontab -r to remove the crontab.
Is there a way to delete just one entry in the crontab??

mkqdisk
mkqdisk(8) Quorum Disk Management mkqdisk(8)
NAME
mkqdisk - Cluster Quorum Disk Utility
WARNING
Use of this command can cause the cluster to malfunction.
SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]]
DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node.
OPTIONS
-c device -l label
Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device
as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one
device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a
RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough
space to hold a UUID created with uuidgen(1).
-f label
Find the cluster quorum disk with the given label and display information about it.
-L Display information on all accessible cluster quorum disks.
-d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect.
