VERITAS Volume Manager 3.5 Release Notes (August 2003)

VERITAS Volume Manager™ HP-UX 11i v2 Release Notes

Patches and Fixes in This Version

Chapter 140

# vxdisk online diskname

This command updates the status of the diskname disk.

# vxdctl enable

This command updates the status of all the VxVM disks.

NOTE The vxdctl enable command initiates an entire disk

device scan. Therefore the length of time VxVM takes

to scan all of the devices in the environment of that

particular host will increase as the number of devices

increases. If you know which disk’s state has been

changed, it is faster to use vxdisk online diskname to

update that disk only.

Run vxdctl enable to Show Status Changes for LVM Disks

• Problem: VxVM output will not reﬂect status changes for LVM disks

until vxdctl(1M) is run. For example, if you clear an LVM disk with

pvremove(1M), vxdiska_list will still list the status of that disk as

“LVM,” until you run vxdctl enable. This is also true for VEA output

and the output from other VxVM commands.

• Workaround: Run vxdctl enable after making any changes to LVM

disks to update VxVM’s database.

VEA Continues Running With No rootdg

• Problem: If rootdg is on an external device which must be shut down,

then VxVM commands cannot run.

• Workaround: None needed—VEA continues to run, although it

cannot complete operations (commands are not being executed).

VxVM and Older Quantum Disk Drives

• Problem: The VxVM makes use of the kernel-to-kernel passthrough

ioctl SCSI command feature in HP-UX. VxVM issues SCSI inquiry

commands to devices on the system to recognize individual disks and

sort out host to device connection pathways.
