Assuming that the disc cannot be recovered by restoring power or plugging a cable in.
First impression is that all you need is to quiesce any applications (i.e. stop the lot) then:
1) Swap the dead disc for a new blank HP-supplied disc which will not have any previous LVM information on it whatsover.
2) Run ioscan -fn and check that the disc has changed from NO_HW to CLAIMED.
If it doesn't recover then you need a hardware engineer to look at the computer in depth.
3) Check the size of the disc with diskinfo and compare with the output of the same command for the good disc (very important, must be equal to or fractionally greater than the size of the good disc). If the disc is small, get another one and do not proceed.
4) Run the vgcfgrestore to the new disc.
Then, make volume group active again:
vgchange -a y vg00
Wait for 5 mins.
5) If you don't find that vgsync is already running (check ps -ef) then issue vgsync vg00.
6) Keep an eye on /var/adm/syslog/syslog.log for progress (it only makes an entry when a sync has completed). This could take several hours.
7) Check periodically on the sync status of all partitions. (Others have posted the commands).
8) When all the partition syncs are complete, relax and start the applications.

QUOTA(2) System Calls Manual QUOTA(2)
NAME
quota - manipulate disk quotas
SYNOPSIS
#include <sys/quota.h>
quota(cmd, uid, arg, addr)
int cmd, uid, arg;
char *addr;
DESCRIPTION
The quota call manipulates disk quotas for file systems that have had quotas enabled with setquota(2). The cmd parameter indicates a com-
mand to be applied to the user ID uid. Arg is a command specific argument and addr is the address of an optional, command specific, data
structure that is copied in or out of the system. The interpretation of arg and addr is given with each command below.
Q_SETDLIM
Set disc quota limits and current usage for the user with ID uid. Arg is a major-minor device indicating a particular file system.
Addr is a pointer to a struct dqblk structure (defined in <sys/quota.h>). This call is restricted to the super-user.
Q_GETDLIM
Get disc quota limits and current usage for the user with ID uid. The remaining parameters are as for Q_SETDLIM.
Q_SETDUSE
Set disc usage limits for the user with ID uid. Arg is a major-minor device indicating a particular file system. Addr is a pointer
to a struct dqusage structure (defined in <sys/quota.h>). This call is restricted to the super-user.
Q_SYNC Update the on-disc copy of quota usages. Arg is a major-minor device indicating the file system to be sync'ed. If the arg parame-
ter is specified as NODEV, all file systems that have disc quotas will be sync'ed. The uid and addr parameters are ignored.
Q_SETUID
Change the calling process's quota limits to those of the user with ID uid. The arg and addr parameters are ignored. This call is
restricted to the super-user.
Q_SETWARN
Alter the disc usage warning limits for the user with ID uid. Arg is a major-minor device indicating a particular file system.
Addr is a pointer to a struct dqwarn structure (defined in <sys/quota.h>). This call is restricted to the super-user.
Q_DOWARN
Warn the user with user ID uid about excessive disc usage. This call causes the system to check its current disc usage information
and print a message on the terminal of the caller for each file system on which the user is over quota. If the user is under quota,
his warning count is reset to MAX_*_WARN (defined in <sys/quota.h>). If the arg parameter is specified as NODEV, all file systems
that have disc quotas will be checked. Otherwise, arg indicates a specific major-minor device to be checked. This call is
restricted to the super-user.
RETURN VALUE
A successful call returns 0, otherwise the value -1 is returned and the global variable errno indicates the reason for the failure.
ERRORS
A quota call will fail when one of the following occurs:
[EINVAL] The kernel has not been compiled with the QUOTA option.
[EINVAL] Cmd is invalid.
[ESRCH] No disc quota is found for the indicated user.
[EPERM] The call is priviledged and the caller was not the super-user.
[ENODEV] The arg parameter is being interpreted as a major-minor device and it indicates an unmounted file system.
[EFAULT] An invalid addr is supplied; the associated structure could not be copied in or out of the kernel.
[EUSERS] The quota table is full.
SEE ALSO
setquota(2), quotaon(8), quotacheck(8)
BUGS
There should be some way to integrate this call with the resource limit interface provided by setrlimit(2) and getrlimit(2).
The Australian spelling of disk is used throughout the quota facilities in honor of the implementors.
