Home -> Community -> Mailing Lists -> Oracle-L -> RE: ASM Startup Help!
So I'm more positive than Scott is. Wonder why that might be? ;)
The first thing I can think to check is if the permissions or access to the= devices has been changed on reboot. The order in which the disks are found= by the RH3 OS can sometimes change on reboot and the persistent binding do= ne between the raw/raw devices and the raw character devices can sometimes = get clobbered. The permissions will sometimes be set for certain devices b= ased on the device number. If the order gets changed and permissions are n= ot accurate, that too can cause a device to not be discovered. This might = be the cause and it might not be. One other question, as Scott mentioned, = is whether you are using ASMLIB or not? If so, the above problems are not = normally an issue. The second question is does this ASM disk group have AS=M redundancy or external redundancy?
Of course, you could always try calling support...
BTW, the PST stands for Partner Status Table and the error message suggest = to me that the disk group does not have the full complement of disks which = it needs to mount the disk group.

Mike, I hate to be the bearer of bad news but I have seen this before when using ASM libs. The case of the disappearing disks. I have had this happen to me on several occasions and now I just don't use the ASM libs anymore. =
The only way your are going to fix this problem is to dd over the device and try to add the disks back into the disk group.
I hope you don't have critical stuff on that diskgroup.
