I'm not sure I get you but if you want to know if you are able to utilize Online JFS to modify a filesystem then you can do a swlist and grep for Online JFS to see if it has been installed, if its not there then you can safely assume that you only have a "base" filesystem which basically means any increase in size as such, the file system will have to be unmounted. ...

If your application is controlled by the cluster then you won't be able to bring the cluster down without halting your application. The best practice is to stop the package from attempting to failover while the outage is occurring and you can also bring the secondary node out of the cluster while its being affected and do a failover and do like wise. that way the outage will occur only during the failover and won't cause any unnecessary outages. worst case scenario, your cluster panics and attempt to failover and can't and it shoots itself in the head... ...

so if you do a strings /etc/lvmtab it actually shows c2t0d0 belonging to vg00? you did vgreduce of c2t0d0 from vg00, correct? did you try doing vgreduce -f c2t0d0 from vg00? ... View more

lets start from the beginning.. what does vgdisplay -v vg00 shows? does it even show c2t0d0? ... View more

vgdisplay will give you the information you need in regards to if a volume group is active or not. just issue vgdisplay | more and this will list all active volume groups and will state if a volume group is not activated on that server. it lists all volume groups, even the ones controlled by Serviceguard. ...

When creating your pvg file you should use the second option: VG /dev/vg01 PVG PVG1 /dev/dsk/c5t0d0 /dev/dsk/c6t0d0 /dev/dsk/c5t1d0 /dev/dsk/c6t1d0 PVG PVG1m /dev/dsk/c5t2d0 /dev/dsk/c6t2d0 /dev/dsk/c5t3d0 /dev/dsk/c6t3d0 this will ensure the mirror is going to the right disks and you have your alternate links to the disks listed as well. ...

first place to find out any hardware logging errors is /var/adm/syslog/syslog.log also you may want to do ioscan -funC disk to check for any NO_HARDWARE errors and if that was the disk with that filesystem located and no mirror copies, then i hope you have a backup. ... View more

another thing you might want to check to expound on Peter's answer... you might want to get very database intrusive, which users are granted what rights, who are given write access to what tables, does everyone have read write access?? also who are permitted to add rows outside of the database admins, what procedures do you follow before making a change to database, do they have a change control policy in place? especially if this is a financial database, you want to get as intrusive as possible because the auditors will show no mercy. ...

even though most wouldn't agree to creating a secondary swap in vg00, but since you don't have many options and you have more then enough space to create additional swap space, then you can create additional swap space with the steps you listed. absolutely, positively do not put it on your shared voludme group, you're asking for trouble... ...

I would not use a shared filesystem to add swap to a server and I'm pretty sure its not recommended. Do you have another volume group on your sever outside of vg00 that is not apart of the cluster? I would use that voluome group to add more swap space. ... View more
