Disk replacement with VxVM

Be aware, that with Solaris 10 and VxVM MP3 a correct disk replacement procedure now looks as described here: # vxdisk rm Offline and Unconfigure the Lun # luxadm -e offline /dev/rdsk/s2 # cfgadm -c unconfigure -o unusable_SCSI_LUN cX:: Cleanup/Recreate device Tree # devfsadm -Cv Recreate and Rescan VxVM devices. # vxddladm stop eventsource # […]

VxVM is watching after you

Couple of days ago my colleague told me about one neat feature of VxVM 5.x that could be quite helpful in the field. Imagine a situation when a customer complains about VxVM misconfiguration and blames your team for a slime work. To prove him wrong, you could sift through VxVMs’ command log files to get […]

Mending VxVM

Last night I was upgrading a domain on our SF6900 box to Solaris 10 and since we use VxVM to mirror our root disk there was no use in preparing dedicated backup neither on tape nor on separate disk because it’s much easier and accurate to split rootdg into two disk groups, e.g. rootdg and […]

Veritas romp

Just came across a really funny piece of code in OpenSolaris. /* * XXX – Don’t port this to new architectures * A 3rd party volume manager driver (vxdm) depends on the symbol romp. * ‘romp’ has no use with a prom with an IEEE 1275 client interface. * The driver doesn’t use the value, […]

Do vxinitrd after kernel upgrade

Just a quick reminder. If you have your root disk on a Linux box encapsulated then don’t forget to recreate initrd image after the kernel has been updated. /usr/lib/vxvm/bin/vxinitrd /boot/VxVM_initrd.img ‘uname -r’ Otherwise you’ll end up being welcomed by the following message once you reboot. Kernel panic – not syncing: Attempted to kill init! Have […]

MPxIO and DMP

It’s highly recommended to set dmp_fast_recovery to off if you use DMP over MPxIO. # vxdmpadm settune dmp_fast_recovery=off For more details refer to the official document

Netbackup’s error 96.

Actually this error is trivially easy to overcome. # bperror -S 96 unable to allocate new media for backup, storage unit has none available The tape manager (bptm) could not allocate a new volume for backups. This indicates that the storage unit has no more volumes available in the volume pool for this backup. Note […]

vxdmpadm path activate weirdness

Just stumbled upon a strange behavior of vxdmpadm which requires further investigation. The problem I’ve faced with during an attempt to set certain path “active” to loadbalance the data flow on HDS between its controllers. The built-in help clearly states that: # vxdmpadm setattr help vxdmpadm setattr path pathtype= pathtype can be either: active nomanual […]

Data restoration from tape

Recently I had to restore some data from a tape written by means of Netbackup, so solely for the reference purposes I decided to write this short post. First we need to mount the tape, I did this using robtest utility, and perfrom a robot’s inventory to make Netbackup aware about a new tape. Keep […]

Missing voolboot file

If executing ” vxdctl enable” you receive the following error: VxVM vxdctl ERROR V-5-1-1589 enable failed: Volboot file not loaded then this sequence could help you to resolve the problem: vxio set 10 vxconfigd -d vxdctl init vxdctl enable Good luck.
