I'm running Solaris 11.2 on a HP Proliant Microserver Gen8. Because of a limited number of hard drive slots, I have installed a SSD in the optical drive bay. Unfortunately, this SATA slot is not bootable (BIOS limitation).So, I have installed Solaris 11.2 on the SSD (where it should run). To make booting to the SSD possible, I have also a SD card in the server and have installed a second instance of Solaris there, just to create the GRUB2 boot menu. When I start the server, I can edit manually the GRUB2 boot menu with the e key, modify the UUID of the boot drive and the server starts from the SSD (instead of SD card) as I planned. The line I modify looks like this:search --no-floppy --fs-uuid --set-root 09bd12det2aag8abHowever, as I discovered, this has to be done every time when starting the server, which is not a good option. How can I modify the GRUB2 boot menu permanently to change the UUID, so that GRUB boots to the SSD drive instead of the SD card?
Permanently modify boot menu on another drive (Solaris 11.2)
boot;solaris;grub2
Boot the alternate SD Solaris instance and add the line to its /rpool/boot/grub/grub.cfg file.Beware that the file might be overwritten by Solaris should your change something in the boot configuration of this Solaris instance using bootadm or similar.
